Description: We now default to i.MX 8X C0 SoC silicon as used on Apalis iMX8X V1.1B and Colibri iMX8X V1.0C and later. However, we also introduced new machines for backwards compatibility reason being called apalis-imx8x-v11a and colibri-imx8x-v10b. Colibri iMX8X V1.0C and later modules also have different RAM chips assembled requiring a different RAMID to be fused. Unfortunately, Colibri iMX8X V1.0B modules produced before 2020/02/04 may not have a proper RAMID fused and therefore won't work with later BSPs starting with BSP 4.0 from June 2020.

Workaround: Please contact Toradex support should you happen to have an early Colibri iMX8X V1.0B module with incorrect/missing RAMID fusing which does not run with BSP 4.0 from June 2020 or later.

Workaround: Just add Status = "disabled" to the toradex,evalspi device tree node and okay to the MCP2515 one.

ELB-1141FixedUpdate libgstnvegl and libgstomx-0.10 to L4T R21.7Apalis TK1MultimediaLowNo

Description: We still had some recipes labelled with 21.5. Going through all our TK1 recipes we identified libgstnvegl and libgstomx-0.10 never actually got updated to building off from R21.7 sources.

Workaround: Fix available on meta-toradex-tegra.git branch rocko-next.

ELB-1139New FeatureMove from CRDA to in-kernel for Wi-Fi Regulatory Domain DatabaseColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Wi-FiLowNo

Description: We switched from CRDA to direct loading of the Wi-Fi regulatory domain database in-kernel.

ELB-1137FixedColibri iMX6ULL/iMX7: Suspend/Resume Regression in 2.8b5Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6Power ManagementLowNo

Description: Resuming after suspend may not work.

ELB-1104FixedKernel Bug when Connecting to the ULLs Bluetooth from AndroidColibri iMX6ULLBluetoothLowNo

Description: If an Android phone is connected to the Colibri iMX6ULL, then an unexpected Linux kernel bug is shown and Bluetooth stops connecting. The only solution is to restart the module.

ELB-1099FixedUpdate Temperature Trip PointsColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6Temperature SensorLowNo

Description: The following temperature trip points are in effect now:
Throttling: 95°C

ELB-1047Fixediptables Not Supported by Default Linux Kernel ConfigurationColibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8EthernetLowNo

Description: iptables -L is not supported by our default Linux kernel configuration.

Workaround: A custom Linux Kernel compilation with correct configuration can solve the issue. The correct Linux kernel configuration is e.g. described here:
https://wiki.gentoo.org/wiki/Iptables

ELB-1031FixedUSB OTG High Speed Host Not Working CorrectlyApalis TK1USBLowNo

Description: Apalis TK1 running BSP 2.8b3 may experience issues connecting USB 2.0 devices to the OTG USB port.

Workaround: Modify the U-Boot defargs environmental variable from "usb_port_owner_info=3" to "usb_port_owner_info=2" to disable USB 3.0 for stable OTG operation. This is now the default as of BSP 2.8b6.

2.8b5 (Release date: 2018-12-28)
ELB-1123FixedLinux Kernel Freeze if M4 Firmware Previously Started From Within U-BootColibri iMX7BootloaderLowNo

Description: Kernel crashes after M4 firmware started. The only log message is "Starting Kernel ...".

Workaround: Enter the following commands in U-Boot: setenv fdt_high=0xffffffff saveenv

ELB-1084FixedEthernet PHY May be Stuck in an Unknown State Doing ifdown/ifupColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6Ethernet, Power ManagementLowNo

Description: Doing ifdown/ifup may leave Ethernet PHY in an unknown state just permanently blinking preventing any communication. This is caused by an Ethernet PHY power-down without physically powering down resp. rail leaving the PHY in an unknown state which later upon powering it back up fails locking PLL. We may just disable PHY power-down bit (already implemented on Colibri VF50/61) or where possible properly implement powering down resp. rail.

ELB-1082FixedCapacitive Touch Not Working ReliablyColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Capacitive TouchLowNo

Description: The touchscreen with 7" Capacitive Touch Display may not work well when used either on an Evaluation Board with the Capacitive Touch Adapter or on Aster or Ixora.

ELB-1067FixedBack Feeding on Ethernet PHY Rail When IP Link is Set DownColibri iMX8X, Colibri iMX7, Colibri iMX6ULLEthernetLowNo

Description: Back feeding on Ethernet rail when Ethernet is powered down.

ELB-996New FeatureUpdate The i.MX Userspace Components to NXP Release imx_4.9.123_2.3.0_gaColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6BuildsystemLowNo

Description: NXP released BSP 4.9.123_2.3.0_ga. Patches for the user space components are in the master branch on meta-freescale. We pulled those into the rocko branch of meta-toradex-nxp.

ELB-995New FeatureUpdate The i.MX Kernel to FSL Community Kernel Based on NXP Release imx_4.9.123_2.3.0_gaColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6KernelLowNo

Description: NXP released BSP 4.9.123_2.3.0_ga. Patches for the user space components are on the meta-freescale mailing list.

Description: Wake from suspend is not working on Colibri iMX6ULL 512MB Wi-Fi / Bluetooth IT.

2.8b4 (Release date: 2018-10-05)
ELB-1519New FeatureOptimize RAM Settings for Colibri iMX6Colibri iMX6BootloaderLowNo

Description: We optimised the RAM setting for Colibri iMX6, enabled dynamic DDR calibration in the SPL and fully validated & verified various modules in our temperature chambers.

ELB-1105FixedSupport Bluetooth 4.2Colibri iMX6ULLBluetoothLowNo

Description: Colibi imx6ull v1.0 supports BT 4.0 and BLE 4.1 Starting with imx6ull v1.1 we support BT\BLE 5.0

ELB-1081FixedCapacitive Touch not Working on AsterColibri T20, Colibri T30Capacitive TouchLowNo

Description: Touchscreen with 7" Capacitive Touch Display does not work when used on an Aster carrier board with a Colibri T20/T30 module.

ELB-1075FixedGpio Tool, IOMUXC SNVS AltFN Wrongly DisplayedColibri iMX6ULLGPIOLowNo

Description: The alternate function of the pins in the IOMUXC SNVS is wrongly displayed. These pins are always GPIO. (TAMPER[0-9], BOOT_MODE[0-1]. Fix this.

ELB-1074New FeatureAdd Device Tree Targeting AsterColibri iMX6ULLDevice TreeLowNo

Description: Add a device tree which targets the aster carrier board. This also enables an easier integration of the Capacitive Touch 7" Parallel display.

ELB-1066FixedUnify Pinmux Settings for flexcanColibri iMX7CANLowNo

Description: We have unused pinmuxings for flexcan1 and flexcan2. Unify the pad settings for the two.

ELB-1065FixedGpio Tool, Muxing of CAN on SODIMM 55/63Colibri iMX7CAN, GPIOLowNo

Description: The CAN muxing ALT2 (can1.RX, can1.TX) for these pins are labelled ftm1.RX, ftm1.TX. Fix this.

ELB-1061FixedCleanup flexcan Device Tree NodesColibri iMX7CANLowNo

Description: The Colibri iMX7 dts files define a flexcan1 node, but the developer webpage https://developer.toradex.com/knowledge-base/can-(linux) only describe how to enable a (non existing) flexcan2 node. Clean that up. Probably one should add in both places the missing node.

ELB-1051New FeatureUpdate Wi-Fi Backports to 4.18Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8Wi-FiLowNo

Description: Update Wi-Fi Backports to 4.18

ELB-1048FixedFirmware on the Cortex-M4 Core might Crash when Loading an elf FirmwareColibri iMX7Miscellaneous PeripheralsLowNo

Description: The firmware might behave erratic/crash when loading using U-Boot bootaux command with an elf firmware.

ELB-1044FixedMore Rare eMMC Communication ErrorsColibri iMX7Flash, SDIO/SD/MMCMediumNo

Description: When running with HS400 at 200 MHz the Kernel may report eMMC errors such as "mmcblk0: error -84 transferring data". Some systems also show "warning! HS400 strobe DLL status REF not lock!". We have not seen issues which lead the system to be completely stuck. However, when using HS200 at 200MHz it affects performance very little (~5%) but seems to run without any errors.

ELB-1042FixedWrong i.MX 6 SoC Version ReportedApalis iMX6, Colibri iMX6CPULowNo

Description: The Linux kernel 4.1.44-2.7.4 may report a wrong i.MX 6 SoC version upon boot:
[ 0.109969] CPU identified as i.MX6Q, silicon rev 0.6

Workaround: The later Linux kernel 4.9.87-2.8.3 does report it correctly:
[ 0.069884] CPU identified as i.MX6Q, silicon rev 1.6
You may find a fix on the toradex_4.1-2.0.x-imx-next branch.

ELB-1034FixedDual CAN Operation on Apalis TK1 May Cause CAN to Stop WorkingApalis TK1CANLowNo

Description: In dual CAN operation, Apalis TK1 CAN may stop working, when error or collision happens on one of the busses.

ELB-1030FixedMissing PullUp on Touch Controller I2CColibri iMX6ULLResistive TouchLowNo

Description: The Colibri iMX6ULL V1.0 and V1.1 HW has no discrete pull ups on the I2C bus to the touch controller. This may lead to unreliable communication with the internal 100k pull ups and the used 80kHz I2C clock.

ELB-1024FixedCAN frames with baud rate different then 1Mbps will be treated as invalid between driver probe and interface upApalis TK1CANLowNo

Description: In a period between driver initialisation and interface bring-up, packets send on the bus with baud rate different then 1Mbps will be treated as invalid.

ELB-1017FixedAdjusting Apalis TK1 LVDS Drive Strength SettingsApalis TK1LVDSLowNo

Description: Apalis TK1 LVDS drive strength settings are hard-coded. Idea is to move those to the device tree as well.

Workaround: For now, settings can be changes in drivers/video/tegra/dc/sor.c file. Function tegra_dc_sor_enable_lvds contains writes to NV_SOR_LANE_DRIVE_CURRENT and NV_SOR_LANE4_DRIVE_CURRENT registers. Registers definitions can be found in the "Tegra K1 Reference Manual".

ELB-1014New FeatureAdd support for new [01491101] CSI Camera Module 5MP OV5640 V1.1BApalis iMX6, Apalis TK1, Apalis T30, Apalis iMX8CSILowNo

Description: The only difference from [01491101] CSI Camera Module 5MP OV5640 V1.1B to the old version V1.1A is about pin 12 (Master clock). This signal isn't used on V1.1B anymore as an oscillator is assembled on the V1.1B version. This improves EMI behavior and also works with SoMs which don't provide a master clock.

ELB-1009New FeatureAssert nRESET_OUT on RebootColibri iMX6ULLPower Management, WatchdogLowNo

Description: The i.MX6 ULL's watchdog is used to reset the SoC on reboot. The watchdog is configured to use the SoC's internal reset signal which does not generate a reset pulse on nRESET_OUT. Change the watchdog configuration to use a SoC external HW signal. This will additionally change the 'Reset cause' message from U-Boot from WDOG to POR. Note that the bmode_usb application in Linux no longer works due to the reset cause change. The behaviour in U-Boot has not been changed, the U-Boot command 'bmode usb' works as before.

ELB-1006FixedFix SGTL5000 VDDA Supply SpecificationApalis iMX6, Colibri iMX6Analog AudioLowNo

Description: Currently, the device tree specifies 2.5V as SGTL5000 VDDA. This is wrong, in practice, the board uses 3.3V Audio voltage as VDDA.

ELB-1005FixedApalis TK1 PCIe Gigabit Bring-up Issue in MainlineApalis TK1Ethernet, PCIeLowNo

Description: Forward ported commit 7ad9771527d2 ("apalis-tk1: fix PCIe reset for reliable gigabit Ethernet operation") was never validated. Turns out it does not work and may lead to PCIe gigabit bring-up issues.

ELB-985New FeatureSupport Colibri iMX6ULL V1.1A SKUsColibri iMX6ULLBuildsystemLowNo

Description: Add support for the new V1.1A hardware revisions of the Colibri iMX6ULL products.

ELB-965FixedLegacy Update Procedure May Fail on Debian Stretch or Arch LinuxColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Generating a legacy update media using Debian Stretch and subsequently updating an Apalis TK1 failed during mounting the root file system.

Workaround: We recommend using the Toradex easy installer on platforms where it is supported. For the legacy update procedure, the easiest is to use one of the supported distributions:
https://developer.toradex.com/knowledge-base/board-support-package/openembedded-(core)#Prerequisites
Other distributions may have the option metadata_csum enabled per default for mkfs.ext4 (Debian Stretch, Arch, ...). This option is not supported on Linux kernels below 3.18 and generates a kernel panic during boot after the legacy update. As a workaround, one can disable this option in /etc/mke2fs.conf before executing the update.sh script. The ext4 man page also has a list of options with their corresponding supported kernels, which may be helpful to refer to in case of legacy update attempts on more exotic systems.

ELB-951FixedDo Not Enforce Building 32-Bit Host BinariesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Enforcing to build 32-bit binaries for native and portions thereof using -m32 in EXTRA_OEMAKE_class-native may lead to the following error when building e.g. u-boot-toradex:
cbootimage: Accessing a corrupted shared library

Workaround: The -m32 as specified in EXTRA_OEMAKE_class-native in recipes-bsp/cbootimage/cbootimage.bb of meta-toradex-tegra may be overridden to your liking. The same applies to the following as well:
meta-toradex-demos: recipes-devtools/mtd/mtd-utils_%.bbappend
meta-toradex-nxp: recipes-devtools/imx-loader/imx-loader_git.bb
meta-toradex-tegra: recipes-bsp/tegrarcm/tegrarcm.bb
meta-toradex-tegra: recipes-support/libcryptopp/libcryptopp_5.6.4.bb

ELB-932New FeatureImage Features do not Work with Toradex Console ImageColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Image features (e.g. tools-debug or others documented at https://www.yoctoproject.org/docs/2.2/ref-manual/ref-manual.html#ref-features-image) do currently not work with the console-tdx-image. The reason is that the image is inheriting from image as opposed to core-image.

Workaround: You may use core-image instead but it might have additional effects.

ELB-915New FeatureDisable Display Backlight before Starting LinuxColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8Bootloader, RGBLowNo

Description: U-Boot typically tears down the display controller before handing control over to Linux. On LCD displays disabling pixel clock leads to a fading out effect with vertical/horizontal lines. Make sure to disable back light before booting Linux.

ELB-871FixedRAM Timing Issues on Colibri VF50/VF61Colibri VF50, Colibri VF61RAMLowNo

Description: Modules with NANYA RAM chips assembled may rarely show timing issues leading to non-booting modules or otherwise unstable behaviour. We adjusted the on-die termination settings and fully validated & verified various modules in our temperature chambers.

ELB-493FixedSupport MXM/SODIMM Pin Numbers to Get/Set GPIOsColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30GPIOLowNo

Description: Allow using MXM or SODIMM pin numbers to get or set GPIOs. This also allows for easier code porting from one to another Toradex module.

ELB-258New FeatureDeploy Device Tree(s)Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, Device TreeLowNo

Description: In OE we build the device trees listed in conf/machine/xxx.conf (build-time variable KERNEL_DEVICETREE) and put them into the image. In the update.sh script we currently also have a variable KERNEL_DEVICETREE with a list of what to put on the update media. We could patch update.sh in OE during image creation time, so that update.sh contains the list from conf/machine/xxx.conf rather than having to maintain that list in both places.

2.8b3 (Release date: 2018-06-27)
ELB-1598New FeatureRS485 SupportColibri iMX6ULLUARTLowNo

Description: Add support for RS485

ELB-1004FixedAudio Codec not WorkingColibri iMX7Analog AudioLowNo

Description: With the toradex_4.9-1.0.x-imx kernel the sgtl5000 audio codec is bound to the I2S interface with the simple card driver but the driver is not part of the kernel config.

Workaround: Add CONFIG_SND_SIMPLE_CARD to the kernel config.

ELB-999FixedFails Poweroff/Shutdown Instead Reboots When Using Mainline LinuxApalis TK1Bootloader, KernelLowNo

Description: The apalis-tk1-mainline machine fails poweroff/shutdown and instead just reboots.

Workaround: The rocko-next branch of meta-toradex-tegra features a patch which disables the AMS AS3722 PMIC's auto power on when AC OK feature otherwise enabled by default and causing a reboot rather than full poweroff.

ELB-998New FeatureRare eMMC Communication ErrorsColibri iMX7FlashLowNo

Description: When running with HS400 at 100 MHz the Kernel may report eMMC errors such as "mmcblk0: error -84 transferring data" during boot-up. In some cases, it might cause the boot process to fail.

Workaround: Running HS400 at 200 MHz seems to work more stable.

ELB-991FixedFix SDK libGL.so, Currently it is a Dangling SymlinkApalis TK1BuildsystemLowNo

Description: In a SDK the symlink sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/lib/arm-linux-gnueabihf/tegra/libGL.so currently points to ./arm-linux-gnueabihf/tegra/libGL.so.1 which does not exist.

Workaround: Fix the symlink in the unpacked SDK: ln -fs libGL.so.1 .../sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/lib/arm-linux-gnueabihf/tegra/libGL.so

ELB-988New FeatureUpdate to NVIDIA's latest Linux for Tegra aka L4T R21.7Apalis TK1Buildsystem, KernelLowNo

Description: Update to NVIDIA's latest Linux for Tegra aka L4T R21.7 https://developer.nvidia.com/linux-tegra-r217.

Workaround: The Linux kernel changes are already available on the toradex_tk1_l4t_r21.7-next branch. The rest of the integration is already available in the rocko-next branch of our meta-toradex-tegra repository.

ELB-982FixedSD Card not Working in U-BootColibri iMX6ULLBootloader, SDIO/SD/MMCLowNo

Description: SD card is not detected in U-Boot even after using "mmc rescan".

Workaround: Fix already available in 2016.11-toradex-next U-Boot branch.

ELB-981FixedYocto Project Layer Readmes May Not be Up-to-dateColibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Our Yocto Project layer readmes may not be up-to-date.

Workaround: Make sure to use valid combinations e.g. as available as tagged repo meta data:
http://git.toradex.com/cgit/toradex-bsp-platform.git

ELB-979FixedOpenCV4Tegra Fails Building Due to Missing DependenciesApalis TK1CSI, GraphicsLowNo

Description: OpenCV4Tegra currently fails to build due to a missing dependency on libpng12.

Workaround: The libpng12 recipe has been re-added to the rocko-next branch of meta-toradex-tegra so OpenCV4Tegra is at least buildable again. However, for full OpenCV4Tegra support, we recommend using NVIDIA's JetPack resp. Linux for Tegra aka L4T as explained in the following article on our developer website:
https://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

ELB-966FixedLegacy Update Procedure Fails on Colibri T20 256MB With Regular LXDE Demo ImageColibri T20BuildsystemLowNo

Description: Unfortunately, starting with BSP 2.8b2 the regular LXDE based demo image root file system reached a size which does no longer easily fit into 256MB of RAM, therefore, failing the legacy update procedure (it may just hang or even crash but definitely fails updating the root file system).

Workaround: Doing the following before 'run setupdate; run update' helps:
setenv fdt_addr_r 0x01000000

ELB-960FixedBuilding on Ubuntu 18.04 FailsColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Building 2.8b2 and earlier fails on Ubuntu 18.04 LTS.

Workaround: It works on Ubuntu 16.04 LTS.

ELB-954FixedColibri iMX6ULL Crashing After Resuming from Suspend on IrisColibri iMX6ULLPower ManagementLowNo

Description: Colibri iMX6ULL Crashing After Resuming from Suspend on Iris

Workaround: A patch is available in toradex_4.9-1.0.x-imx-next "arm: imx: gpc: do not poweroff M/F mix in suspend"

ELB-944FixedRegression: PCI Express Failing to Enumerate on Apalis iMX6Apalis iMX6Kernel, PCIeLowNo

Description: While BSP 2.8b1 enumerated PCIe on the Apalis evaluation board just fine BSP 2.8b2 may fail with the following error message:
busn_res: can not insert [bus 02-01] under [bus 01] (conflicts with (null) [bus 01])

Workaround: As a workaround you may just revert the following offending commit for now:
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_4.9-1.0.x-imx&id=9a4bf05126f42c2632729ab0da503021d74ed454

ELB-943FixedLegacy Update is not Deploying V1.2 Device TreeApalis TK1BuildsystemLowNo

Description: Apalis TK1 legacy update is not deploying the v1.2 devicetree.

Workaround: Use Toradex Easy installer or u-boot ums mode.

ELB-937FixedRS485: Using RTS to Control the Transceiver is not WorkingColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6UARTLowNo

Description: RS485 with using RTS to control the transceiver is not working. The RTS signal is not asserted during transmission. This is a regression in 2.8 BSPs (Linux kernel 4.9).

Workaround: Use ioctl to configure RS-485 and set the flag SER_RS485_RX_DURING_TX and SER_RS485_RTS_AFTER_SEND.

ELB-936New FeatureAdd libsoc to Image RecipesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Apalis iMX8GPIOLowNo

Description: libsoc is a C library to interface with common peripherals found in System on Chips (SoC) through generic Linux Kernel interfaces. As libsoc supports more and more of our modules we add libsoc support to our regular images.

ELB-930FixedOverruns on UART Without DMA Lead to FIFO Out-Of-SyncColibri VF50, Colibri VF61UARTLowNo

Description: When the UART without DMA (fsl_lpuart.nodma=1) overruns, the FIFO can get out of sync. Once out of sync, characters appear delayed only after new characters have been received.

Workaround: Reopen UART in case overruns have been detected (see /proc/tty/driver/fsl-lpuart). Use UART in DMA mode makes overruns less likely to occur and seems not to suffer issues on overruns.

ELB-929FixedFraming Errors on UART With DMA Lead to FIFO Out-Of-SyncColibri VF50, Colibri VF61UARTLowNo

Description: When the UART with DMA (default) receives a character with framing errors (e.g. due to a break signal) the FIFO can get out of sync. Once out of sync, characters appear delayed only after new characters have been received.

Workaround: Reopen UART in case overruns have been detected (see /proc/tty/driver/fsl-lpuart). Use UART without DMA which handles Framing Errors correctly.

ELB-928FixedOnly Evaluation Board Device Trees Got Updated, Others May Have DivergedColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6Device TreeLowNo

Description: When migrating to the Linux kernel only the evaluation board device trees got updated, others may have diverged. This is especially the case with the Colibri camera device tree concerning e.g. RTC and new capacitive touch aka mxt.

ELB-927FixedColibri iMX7 Dual 1GB Aka eMMC SKU U-Boot Missing Fatwrite Command SupportColibri iMX7Bootloader, Flash, SDIO/SD/MMCMediumNo

Description: While all other eMMC based Toradex SoMs do support the fatwrite U-Boot command the Colibri iMX7 Dual 1GB currently does not. This is especially sad should anybody try using any legacy update procedure e.g. just for flashing the M4 firmware.

Workaround: For now just use UMS, do it from Embedded Linux user space or use the Toradex Easy Installer with a custom image JSON.

ELB-926FixedToradex Configuration Block Off by One IssueColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, ConfigBlockLowNo

Description: Currently the Toradex configuration block parser suffers an off by one issue potentially leading to spurious printout during boot e.g.
Model: Toradex V1.2A,
instead of
Model: Toradex UNKNOWN MODULE V1.2A.

Workaround: Fix available on 2016.11-toradex-next branch of git.toradex.com/u-boot-toradex.git.

ELB-925FixedCan Not Install Individual Backport Kernel ModuleColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Installing a single backport kernel module to an image at build time fails (e.g. by using IMAGE_INSTALL_append in local.conf).

Workaround: Install all backport kernel modules by using the "backports" package.

ELB-916FixedAdd Atmel mxt touch controller driver support for reset gpioColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8Capacitive TouchLowNo

Description: To get atmel mxt based touchscreens with GPIO connected reset line to work GPIO needs to be configured as an output with appropriate level separately.

ELB-906FixedMake Latest OE-Core, Morty Compatible With meta-toradex-bsp-commonColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: OE-Core layer did backport more package splits in the linux-firmware recipe. Due to this the HEAD of the morty branch clashes now with a similar split we did in meta-toradex-bsp-common resulting in a fatal QA error. (Compare with commit 0eaef98) ERROR: linux-firmware-1_0.0+gitAUTOINC+bf04291309-r0 do_package: QA Issue: linux-firmware-sd8887 is listed in PACKAGES multiple times, this leads to packaging errors.

ELB-859FixedSupport For AP Mode on Built-in Wi-FiColibri iMX6ULLWi-FiLowNo

Description: The built-in/on-module Wi-Fi of the Colibri iMX6ULL 512MB Wi-Fi / Bluetooth IT module currently does not support the access point aka ap mode.

Workaround: You may force the mwifiex driver to create two interfaces during initialization
echo "options mwifiex driver_mode=0x3" > /etc/modprobe.d/mwifiex.conf
The interface mlan0 is a regular station interface while the uap0 interface can be used as an access point.

ELB-514New FeatureSupport USB 3.0 SuperSpeed on USBO1Apalis TK1USBLowNo

Description: Support USB 3.0 SuperSpeed on USBO1.

Workaround: Use USB 3.0 SuperSpeed on USBH4 for now. Alternatively, the mainline Linux kernel already supports USB 3.0 SuperSpeed on USBO1 as well as USBH4. You may also use the latest mainline Linux based demo image Apalis-TK1-Mainline_LXDE-Image as can be found at http://developer.toradex.com/files/toradex-dev/uploads/media/Colibri/Linux/Images/.
Such fix/support may now be found in the 2016.11-toradex-next U-Boot and toradex_tk1_l4t_r21.6-next Linux kernel branches of our git repositories.
Please note that one may not switch back to USB device functionality once USB 3.0 SuperSpeed host functionality has previously been used.

ELB-462FixedSPDIF not WorkingApalis iMX6, Colibri iMX6Digital AudioLowNo

Description: SPDIF is not working in the V2.6 beta 2 release. This is a regression against older releases.

Workaround: Fixes found in the -next branches of our 3.14, 4.1 and 4.9 based Linux kernels.

2.8b2 (Release date: 2018-03-31)
In this release we switched to the generic compressed Kernel image type (zImage) instead of the legacy U-Boot specific uImage format. This could lead to non booting modules if a previously saved U-Boot environment is still set to uImage. Please see the following issue for more details: http://developer.toradex.com/software/linux/linux-software/release-details?view=all&issue=17925

ELB-897FixedBitbaking stress Reports Checksum MismatchColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: When building 2.8b1 building stress fails with "ERROR: stress-1.0.4-r0 do_fetch: Fetcher failure for URL: 'http://people.seas.harvard.edu/~apw/stress/stress-1.0.4.tar.gz'. Checksum mismatch!".

Workaround: Use 2.8b2 or remove the stress recipe under "meta-toradex-demos/recipes-support/stress/stress_1.0.4.bb" (this will use a fixed version of stress in openembedded-core/meta/recipes-extended/).

ELB-891FixedSwitching From USB Client to Host Not Working On BSP 2.8b1Colibri iMX6ULLUSBLowNo

Description: The USBC port does only work in device mode. Switching to host does not work. This is a regression introduced with the move to the 4.9 kernel version.

Workaround: Cherry-pick the following commit: 'ARM: dts: imx6ull-colibri: Specify cable detect as ID and VBUS pin' and recompile and deploy the device tree.

ELB-877FixedImage Viewer gpicview is no Longer in Demo ImageColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, GraphicsLowNo

Workaround: Remove adwaita-icon-theme from BAD_RECOMMENDATIONS when building the image with openembedded.

ELB-870FixedInternal RTC Not AvailableColibri iMX7Device Tree, RTCLowNo

Description: The internal aka on-module RTC is not available since we migrated to the Linux 4.9 kernel (2.8b1).

ELB-854FixedMissing Temperature Sensor on Colibri iMX7SColibri iMX7Temperature SensorLowNo

Description: The thermal sensor driver on i.MX 7Solo does not probe successfully. There is no thermal sensor data available.

ELB-853FixedSystem Freeze After MCP2515 Initialization on Colibri iMX7S in 2.8b1Colibri iMX7KernelLowNo

Description: The system freezes during boot shortly after initializing the MCP2515 CAN controller. The CAN controller triggers a (re)probe of the thermal driver which fails to probe during boot. This late probe causes the driver to access OTOCP registers which are not clocked anymore.

Workaround: Add clk_ignore_unused to defargs in the U-Boot command line (e.g. by using "setenv defargs ${defargs} clk_ignore_unused").

ELB-819New FeatureProvide LXQt Demo Image Similar to LXDE OneColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Remove snapd from standard images.

ELB-784FixedApalis TK1 Increase CAN SpeedApalis TK1CANLowNo

Description: Target is to achieve >2k msg/s (1Mbit/s) on both CAN channels.

ELB-773New FeatureAllow eDP/LVDS Graphics Configuration via Device TreeApalis TK1eDP, Graphics, LVDSLowNo

Description: Currently this is hard-coded in some board resp. panel platform files making it rather difficult to test various options around eDP/LVDS. NVIDIA's implementation has partial support for device tree which needs extending and testing.

ELB-742FixedBuild Failure When Building Image the Next Day Without ChangesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: After building an image completely successfully, building the same image the next day without any changes leads to an error "do_image_teziimg: Error executing a python function in exec_python_func()".

Workaround: Make an unrelated change in any recipe to force recreation of the rootfs.

ELB-667New FeatureAdd Option to Specify 24BPP LVDS Output FormatApalis TK1Graphics, LVDSLowNo

Description: Add an option to sepcify the 24bpp LVDS output format which is currently hard-coded to what NVIDIA calls 24.0 in their TRM. The alternate option would be called 24.1.

ELB-616FixedU-Boot: Allow to Use SODIMM 169 as a GPIOColibri iMX7BootloaderLowNo

Description: Pads not used in U-Boot are accessible via GPIO command. However, SODIMM 169 is currently not available and is driven high at the moment in U-Boot.

ELB-583FixedRecovery U-Boot for iMX6Apalis iMX6, Colibri iMX6BootloaderLowNo

Description: We moved a while ago to a SPL/u-boot.img approach. The SPL runs in SRAM and configures the DDR-RAM, then it loads U-Boot proper into DDR and passes control. In the legacy update procedure, the recovery mechanism however stayed with a monolithic u-boot.imx binary which had to be built separately. Change also the recovery procedure to a download chain of first loading SPL and then u-boot.img. Note that the Toradex Easy Installer works that way successfully for some time.

ELB-565New FeatureImprove angstrom-qt5-x11-Image by Using xinit to Start XColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Currently, we use an init script which starts X directly and then a Qt demo application. This has some drawbacks, e.g. when one wants to start a touch calibration or the likes. Use some readily available X startup system, e.g. xinit as a better base customers can build upon.

Workaround: Please find a suitable systemd service in the following recipe:
http://git.toradex.com/cgit/meta-toradex-demos.git/tree/recipes-images/images/angstrom-qt5-x11-image.bb?h=rocko#n4

ELB-414New FeatureSwitch to zImage Instead of uImageApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30KernelLowNo

Description: Switch to the generic compressed Kernel image type (zImage) instead of the legacy U-Boot specific uImage format.

Workaround: Please note that if one is updating from an earlier release one may have to manually fix the U-Boot environment to take this into account as mentioned on the community forum at https://www.toradex.com/community/questions/19860/bsp-28b2-fails-to-load-linux-kernel-due-to-uimage.html

2.8b1 (Release date: 2017-12-29)

Description: Include hostapd in demo builds. Note that this is only about the naked daemon without any configuration which depends on resp. requirements. So nothing of the hostapd will be automatically started by default.

ELB-827FixedDrop Support for Apalis iMX6 V1.0 HWApalis iMX6Device TreeLowNo

Description: The early sample hardware Apalis iMX6 V1.0A/B have a different UART pin-out which require a specific device tree. Starting with 2.8 Beta 1 we no longer provide these device trees.

Workaround: Use an older BSP or forward port the relevant changes between the device tree targeting the later HW vs. V1.0 HW.

ELB-826FixedBoth fchdir() And fstat() Fail With EBADF When File Was Previously Opened with O_PATH Flag on T20/T30Colibri T20, Colibri T30, Apalis T30KernelLowNo

Description: On Apalis/Colibri T20/T30 both fchdir() and fstat() fail with EBADF when the file was previously opened with the O_PATH flag.

Workaround: Required patches have been backported to our downstream Linux kernel: http://git.toradex.com/cgit/linux-toradex.git/log/?h=tegra-next

ELB-794New FeatureUpdate Bluetooth/Wi-Fi Backports to Latest Linux Kernel Mainline (LTS) ReleaseColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bluetooth, Buildsystem, Kernel, Wi-FiLowNo

Description: We are currently using 4.11 which is not really an LTS release however we opted to do that because we were relying on it for certain later features for certain Wi-Fi solutions we wanted to support. It may make sense to stabilise on an LTS release for the future.

Workaround: You may find our backports based on Linux kernel 4.14 here: http://git.toradex.com/cgit/backports-toradex.git/log/?h=toradex-4.14

ELB-792New FeatureUpdate to Latest Linux Kernel Mainline 4.14 LTS ReleaseApalis TK1KernelLowNo

Description: Update apalis-tk-mainline machine to latest Linux kernel mainline 4.14 LTS.

ELB-790FixedApalis/Colibri T30 PWM Capped at 12.45kHz.Colibri T30, Apalis T30PWMLowNo

Description: Apalis/Colibri T30 PWM was capped at 12.45kHz. We've increased it to 99.6kHz that can be further divided by integer divider.

Workaround: PWM peripheral input clock value can be increased to a maximum of 48MHz. Valid clock values can be calculated pwm_clk = 408MHz/N, where N=<1 , 128.5> in 0.5 increments

ELB-783FixedMissing DRI_PRIME=1 Environment Variable Required For OpenGL ESApalis TK1GraphicsLowNo

Description: While BSP 2.8b1 does no longer require any special handling older BSPs apalis-tk1-mainline Mesa needed DRI_PRIME=1 to be defined as environment variable in order for OpenGL ES applications like glmark2-es to work right.

Workaround: In older BSPs adding DRI_PRIME=1 environment variable is required for OpenGL ES.

ELB-779New FeatureUpdate the i.MX Kernel to FSL Community Kernel Based on NXP Release imx_4.9.11_1.0.0_gaColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6KernelLowNo

Description: Update to NVIDIA's latest Linux for Tegra aka L4T R21.6 https://developer.nvidia.com/linux-tegra-r216.

Workaround: The Linux kernel changes are already available on the toradex_tk1_l4t_r21.6-next branch. The rest of the integration is already available in the morty-next branch of our meta-toradex-tegra repository.

ELB-797New FeatureCreate NVIDIA JetPack Toradex Easy Installer ImageApalis TK1BuildsystemLowNo

Description: It would be very convenient to just be able to install NVIDIA's JetPack via Toradex Easy Installer once available for Apalis TK1.

Workaround: For now just stick to the rather cumbersome manual installation procedure: http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

ELB-795FixedDDC/EDID Detection Failing on IxoraApalis TK1Graphics, HDMI, I2CLowNo

2.7b4 (Release date: 2017-10-05)
In this release we changed to use Ext4 file system by default. This could lead to non booting modules if a previously saved U-Boot environment is set to non-ext4. Please see the following issue for more details: http://developer.toradex.com/software/linux/linux-software/release-details?view=all&issue=27678
ELB-1517New FeatureImprove RAM Settings for Colibri iMX7Colibri iMX7BootloaderLowNo

Description: Use optimized RAM timings as we found some issues on some modules and in our temperature testing.

ELB-817FixedMissing PWM Support Leaves Some Display Backlights OffColibri iMX6ULLPWMLowNo

Description: As PWM support is currently not available the PWM pin (SODIMM 59) is statically set to output with the value '0' in the regular U-Boot and to an input with pullup in the case of the Toradex Easy Installer. If a connected display has its backlight off in that case one ends up with a dark display. The VGA (RGB DAC) output is not affected.

Workaround: - On the Evaluation Board remove the PWM jumper and hard-wire the desired level. - For a regular image one can change the value from the U-Boot command line: 'gpio set 107'. E.g. add that as the first command to the bootcmd environment variable. - For the Toradex Easy Installer one can configure the pin to gpio and set a value from the U-Boot command line: 'mw.l 020e01a4 5 1; gpio clear 107'.

ELB-774New FeatureSupport Toradex Easy Installer Package Format for Apalis TK1 ModulesApalis TK1BuildsystemLowNo

Description: Provide the Apalis TK1 BSPs also in a Toradex Easy Installer package.

ELB-758FixedNo PWM Functionality on Apalis PWM3 PinApalis TK1PWMLowNo

Description: While the Apalis PWM3 pin is shared with the Apalis BKL1_PWM pin currently the former does not have the PWM pin muxing activated. Note that exporting PWM3 for raw sysfs access will therefore fail and one has to revert to using the pwm backlight.

Workaround: Change resp. pin muxing in the device tree. You may find a patch on our toradex_tk1_l4t_r21.5-next branch.

ELB-749FixedConfig Block Check During Update May Fail Depending on Hardware Area Boot Partition SizeColibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30Bootloader, BuildsystemLowNo

Description: The config block check aka check_configblock may fail during update depending on the size of the hardware area boot partition which may lead to the config block not getting properly migrated or updated if still using parts of the legacy update procedure.

Workaround: Use U-Boot's built-in 'cfgblock create' functionality or use the Toradex Easy Installer where applicable. Alternatively find fixed legacy U-Boot update scripts in the -next branch of our meta-toradex-demo repository.

ELB-748FixedEnable Second CAN ChannelApalis TK1CANLowNo

Description: Target is to achieve >2k msg/s on both CAN channels.

ELB-740FixedPotential Gigabit Ethernet resp. PCIe InstabilityApalis TK1Bootloader, Ethernet, Kernel, PCIeLowNo

Description: So far in U-Boot we violated the PCIe reset timing specification and in Linux we did not do anything about doing the PCIe reset unisono with the separately switchable voltage rail of the gigabit Ethernet chip.

Workaround: A solution to the U-Boot side of things may be found on our -next branch now.

ELB-736FixedDefine Standard Rootfs Mount Behaviour and OptionsColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, FlashMediumNo

Description: The kernel does not know about rw,noatime. The string rw by itself is valid, and to pass additional arguments rootflags=noatime can be used. The kernel mounts ext3/ext4 file systems by default ro, hence so far the kernel mounted the rootfs read-only. The init manager systemd then remounts the rootfs after file system checking. This makes sense and does not add measurable boot time. Let the kernel explicitly mount ro on block device based rootfs. The root mount flag noatime is only relevant when re-mounting read-write, hence it needs to be present in /etc/fstab. UBIFS used on raw NAND devices has no user space file checking, hence there is no value to mount it in read-only first. Also mount time for UBIFS is larger, and mounting first read-only and then read-write has higher boot time (300ms, likely due to missing block cache). Let the kernel explicitly mount rw on raw NAND based rootfs. UBIFS has no atime support, hence no root mount flags needed.

Workaround: The change to initially read-only mounted root file system on Apalis TK1 requires the U-Boot emmcargs environment variable to be adjusted to run NVIDIA's JetPack resp. L4T as documented here: http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1#Flashing_Latest_Boot_Loader

ELB-730FixedOnly 256MiB of Memory Available When Running Cortex-M4 Core on Colibri iMX7DColibri iMX7Kernel, RAMLowNo

Description: The Colibri iMX7D has 512MiB of memory. However, when running the Cortex-M4 core only half of the memory is available in Linux.

ELB-725Fixed'run update' Fails if the Rootfs is Exactly a Multiple of 64MApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30BootloaderLowNo

Description: If an image creates a rootfs which is exactly a multiple of 64 MByte and then if one executes in U-Boot 'run update' the detection that all 64 MByte chunks have been flashed fails and the update never completes. Note that the Toradex Easy Installer is not affected.

Workaround: Check the last rootfs chunk on the update media and create a zero length chunk with incremented number, e.g.: $ ls -l //colibri-imx6/ ... -rw-r--r--. 1 root root 67108864 Jul 12 15:13 root.ext3-106 -rw-r--r--. 1 root root 67108864 Jul 12 15:13 root.ext3-107 -rw-r--r--. 1 root root 48128 Jul 12 15:13 SPL ... $ touch //colibri-imx6/root.ext3-108

ELB-722New FeatureDeploy a bmode CLI Equivalent for LinuxApalis iMX6, Colibri iMX6Miscellaneous PeripheralsLowNo

Description: While we developed the bmode_usb utility we missed actually deploying it in any of our images.

Workaround: However the recipe http://git.toradex.com/cgit/meta-toradex-nxp.git/tree/recipes-support/bmode-usb?h=morty does exist and may be built and deployed manually.

ELB-721FixedDeploy Apalis iMX 6 Device Tree Tailored to Ixora V1.1Apalis iMX6KernelLowNo

Description: We forgot to actually deploy the new device tree: imx6q-apalis-ixora-v1.1.dtb.

Workaround: Just checkout the Linux kernel sources, build the device trees and copy imx6q-apalis-ixora-v1.1.dtb to the update SD card into the apalis_imx6 folder. Then in U-Boot first 'setenv fdt_file imx6q-apalis-ixora-v1.1.dtb; saveenv' and do a 'run setudpate; run update_fdt'.

ELB-720FixedParallel RGB Display and/or SD Card May Not Work Reliably on Latest ModulesColibri iMX7CAN, Device Tree, GPIO, Graphics, RGB, SDIO/SD/MMCLowNo

Description: Note: This is only an issue for Colibri iMX7S 256MB V1.1C and Colibri iMX7D 512MB V1.1D and later modules.
As it turns out not using LDO2 anywhere at all in the regular case is a bad idea leading to the following:
[ 2.317688] LDO2: disabling
Of course display and SD card still worked on the EvalBoard due to back feeding through some pull-ups however on Viola with just one pull-up it failed once both display and SD card were active...
Currently without an SD card inserted the regulator framework actually powers the LDO2 off however e.g. the BL_ON pin is also on that same rail!

Workaround: The following fixes were integrated:
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_4.1-2.0.x-imx&id=0284f779bba00b930bd9bb12703e2092478531c7
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_4.1-2.0.x-imx&id=ac8dcd0d7b7d17ad8ac42b42cb1f51d4417f4950
Fix this by specifying LDO2 to be always on and use the regular 3.3V supply from the carrier board as the vmmc-supply.
Specify that carrier board 3.3V supply to be always on as well to avoid the following misleading message during boot:
[ 2.299654] 3.3V: disabling
One remaining issue is that now in suspend LDO2 is still powered and even adding the following did not help:
regulator-state-mem {
    regulator-off-in-suspend;
};
Further investigation pending.

ELB-719FixedPower I2C Bus Communication Speed Should be Reduced to 100 KHzColibri T20, Colibri T30, Apalis T30I2C, Power ManagementLowNo

Description: Power I2C bus communication speed should be reduced to 100 KHz as our temperature sensor chip LM95245 is not rated for higher speeds.

ELB-716FixedInclude Gstreamer 0.10Apalis TK1MultimediaLowNo

Description: Unfortunately our current Angstrom/OpenEmbedded/Yocto BSP exclusively uses gstreamer 1.0 which we learned from multiple sources is not really production ready for TK1. We may consider switching to or at least including gstreamer 0.10 in the future as well.

Workaround: Use JetPack for now which allows installing both gstreamer 0.10 as well as 1.0. http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

ELB-715New FeatureMCC Integration to Run eCos or MQX on Latest BSPsColibri VF61Miscellaneous PeripheralsLowNo

Description: When migrating from older stable Colibri VF61 BSPs to later BSPs the MCC functionality got replaced by rpmsg. In order to be able to continue running existing eCos or MQX implementations on the M4 core the MCC functionality would be needed. A fix is pushed to the mcc kernel module: https://github.com/toradex/mcc-kmod/commit/083388fa5cce79c239988d61543322d91996aa8d

Description: Support forcing U-Boot's 'cfgblock create' command to overwrite an existing config block e.g. using a -y parameter and therefore not prompting the user for easier scripting.

ELB-704New FeatureUse Ext4 File System by DefaultApalis iMX6, Colibri iMX6, Apalis TK1FlashLowNo

Description: Use the ext4 file system by default.

Workaround: Please note that if one is updating from an earlier release one may have to manually fix the U-Boot environment to take this into account as mentioned on the community forum at https://www.toradex.com/community/questions/16464/image-27b4-fails-to-mount-rootfs.html

Description: Currently various things may fail or behave strangely on certain modules if the config block is missing. Unify that behaviour by e.g. rather not allowing use of any features (e.g. Ethernet, RNDIS) at all in this case.

Workaround: Use the 'cfgblock create' U-Boot command to restore the config block. Alternatively we implemented similar functionality into our Toradex Easy Installer.

ELB-681New FeatureAdd support for LM816 (RTL8188EU)Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Wi-FiLowNo

ELB-896New FeatureSGTL5000 Audio Multi Instance Codec DriverColibri iMX7, Apalis iMX6, Colibri iMX6Analog AudioLowNo

Description: The SGTL5000 driver in the Linux Kernel currently only supports one codec. The driver would need amending so that multiple codecs can be used. The issue is the statically created VDDD_LDO regulator.

Workaround: For i.MX based modules update to BSP 2.7b3 or later. With the backport of 'ASoC: sgtl5000: Fix regulator support' into the toradex_4.1-2.0.x-imx this driver limitation has been removed.

ELB-709FixedCPU Frequency on Colibri iMX7 Solo Scales up to 1GHz Outside of SpecColibri iMX7CPULowNo

Description: The i.MX 7Solo is only rated up to 800MHz, hence operating it at 1GHz is outside of the official specification. There have been no negative effects observed.

Description: There is now an experimental meta-snappy which allows regular Yocto project BSPs to support running Ubuntu Core snaps. Integrate this in our regular demo images.

ELB-695FixedSupport RS485 Enabled at Boot Time Device Tree PropertyColibri iMX7, Apalis iMX6, Colibri iMX6UARTLowNo

Description: In the 3.14 based kernels the device tree property "linux,rs485-enabled-at-boot-time" allowed to enable RS485 at boot time. This device tree property so far had no effect on 4.1 based releases.

Workaround: This is now implemented in our toradex_4.1-2.0.x-imx-next branch.

ELB-673FixedSometimes the RTC Driver Recovers Invalid Date/Time from the External RTCColibri VF50, Colibri VF61RTCLowNo

Description: After the RTC has been under-powered, some RTC deliver invalid date/time. The external RTC currently shipped on Toradex evaluation boards has a oscillator fail bit which indicates when RTC does not contain a valid date/time.

ELB-663FixedLVDS Device Tree Timings May Lead to Kernel CrashApalis iMX6LVDSLowNo

Description: Specifying display timings in device tree and only using minimal boot arguments (e.g. video=mxcfb3:dev=ldb,bpp=32) leads to a kernel crash.

ELB-661Fixedsdboot Using ext4 Rootfs FailsApalis TK1BootloaderLowNo

Description: Trying to sdboot from an ext4 rootfs fails due to us defaulting to ext3. While the downstream T20/T30 L4T kernel has issues with ext4 later TK1 L4T should work just fine with it.

Workaround: Just change the sdargs to ext4 as follows: setenv sdargs 'ip=off root=/dev/mmcblk1p2 rw rootfstype=ext4 rootwait'

ELB-657FixedImages: Configure systemd Without ACL SupportColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Using ACL with ubifs seems to increase the likelihood of filesystem corruption. Since ACL is an optional features and unlikely necessary on an embedded system switch ACL off.

ELB-654FixedImplement/fix wake up on CAN for modules with FlexCANColibri iMX7, Apalis iMX6, Colibri iMX6CANLowNo

Description: Wakeup on CAN does not work in suspend mode with FlexCAN with 4.1.39 kernel.

ELB-633New FeatureDevelop a bmode CLI Equivalent for LinuxApalis iMX6, Colibri iMX6Miscellaneous PeripheralsLowNo

Description: Add a Linux accessible way to set the boot mode for the next warm start to be 'serial download mode' aka. 'recovery mode' to ease updating the module. Binary is called 'bmode_usb'.

ELB-629FixedModule May Hang During Boot Upon Hardware ResetColibri T30, Apalis T30Bootloader, Kernel, Power ManagementLowNo

Description: Depending on its DVFS state right before hardware reset the Apalis/Colibri T30 module may hang during a subsequent boot. Software reset seems not affected.

Workaround: Either power-cycle or make sure you are running at a higher DVFS state upon hardware reset. A fix for this called 'apalis/colibri_t30: improve vdd core pmic handling' may be found on our U-Boot 2016.11-toradex-next branch.

ELB-599New FeatureUpdate to Yocto Project Jethro Release 2.0.3Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

ELB-652FixedGPIO Tool: Fix Pinmuxing for NANDF_D4 (Apalis iMX6) and Apalis GPIOs (Apalis TK1)Apalis iMX6, Apalis TK1GPIOLowNo

Description: Apalis iMX6: The gpio-tool can not read or change the current pinmuxing of the NANDF_DATA4 pin but rather the SD4_DAT6 pin got changed instead. Apalis TK1: Some of the Apalis GPIOs were not accessible with the gpio-tool.

Workaround: Don't use the gpio-tool for pin NANDF_DATA4 on Apalis iMX6.

ELB-650New FeatureNew Versioning SchemeColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: We changed our versioning scheme. Our BSP demo image packages are now e.g. called Apalis-iMX6_LXDE-Image_2.7b2-20170410.tar.bz2. The Linux kernel will report e.g. the version number 4.1.39-2.7.2+gba2f75f and U-Boot will report e.g. 2016.11-2.7.2+g60021a4. Details about the versioning can be found here: https://developer.toradex.com/knowledge-base/toradex-software-versioning-convention

ELB-648FixedRegression: Poweroff when PoweroffApalis iMX6, Colibri iMX6Kernel, Power ManagementLowNo

Description: Since the move to the toradex_4.1-2.0.x-imx kernel poweroff fails powering off the PMIC once Linux reached halt.

Workaround: One could poweroff the carrier board by using a GPIO. http://developer.toradex.com/knowledge-base/gpio-(linux)#GPIO_PowerOff

ELB-639FixedPotential Systemd Hang on First BootColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Systemd may hang upon first boot due to certain services like run-postinsts and opkg-configure triggering a configuration reload later causing dynamic device services like the dev-ttyS0 one to hang.

Workaround: A fix has been implemented in our -next branch.

ELB-637FixedModules May Hang During RAM InitialisationColibri VF50, Colibri VF61Bootloader, RAMLowNo

Description: A few Colibri VF50/VF61 (IT) modules flashed with our latest beta BSP release V2.7Beta1_20170112 may hang during DRAM initialization (e.g. right after printing DRAM:). Attempting recovery with that same beta release will likewise fail.

Workaround: This is a software regression in U-Boot. Either compile U-Boot from our -next branch or use our latest stable BSP release V2.5_20151216 which has been fully validated & verified and does not exhibit this issue.

ELB-635FixedModule May Draw More PowerColibri T20Graphics, KernelLowNo

Description: Colibri T20 modules may draw more power be it during regular operation or in suspend.

Workaround: This issue is related to the 'Module May Hang During Boot if HDMI is not Connected' one whose fix can be found on the tegra-next branch of our linux-toradex Linux kernel repository: http://git.toradex.com/cgit/linux-toradex.git/log/?h=tegra-next

ELB-627FixedHDMI Hot-Plugging Fails Configuring Desktop OutputApalis TK1, Colibri T20, Colibri T30, Apalis T30HDMILowNo

Description: The udev rule /etc/udev/rules.d/hdmi.rules which should take care of this now fails with exit code 1. It looks like the RUN part of that rule should be reworked into its separate unit file to be spawned using SYSTEMD_WANTS.

Workaround: Manually call xrandr to get the desired effect.

ELB-620FixedAdapt Wrap-up Script for Colibri iMX6Colibri iMX6BuildsystemLowNo

Description: The wrap-up script in the Toradex Easy Installer Colibri iMX6 V2.7 Beta 1 image does not allow to flash Colibri iMX6 modules.

Description: After the RTC has been under-powered, some RTC deliver invalid date/time. The external RTC currently shipped on Toradex evaluation boards has a oscillator fail bit which indicates when RTC does not contain a valid date/time.

ELB-595New FeatureU-Boot SPL Version HandlingApalis iMX6BootloaderLowNo

Description: With our unified (Linux/WEC) SPL in place we need a way to tell what version of SPL thereof is installed.

ELB-590FixedNo Longer Spawn getty on USB Serial GadgetColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61UARTLowNo

Description: On modules with newer kernels we set up a composite USB gadget with an RNDIS and a ACM USB endpoint providing a virtual Ethernet and serial link on the USB client port. Currently for Colibri VF a getty is spawned on the serial link giving you a login console on that connection. All other modules do not spawn a getty. We no longer spawn a getty on any module since some host platforms do have issues with composite USB gadgets.

Workaround: Please have a look at the following article on our developer website for more information: http://developer.toradex.com/knowledge-base/usb-device-mode-(linux)

ELB-586New FeatureRemove Unneeded RDEPENDS From Our RecipesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Bitbake for some time checks what other packages a package depends on by e.g. examining the output of ldd of a binary or examining used interpreters in scripts. So RDEPENDS are only needed for non obvious packages, e.g. such which get dynamically linked in code or packages providing data. Cleanup our layers.

ELB-572FixedUBI/UBIFS Issues on Colibri VF50/VF61: Crash During Filesystem Recovery After an Unexpected Power CutColibri VF50, Colibri VF61FlashMediumNo

Description: On Colibri VF50/VF61 in situations with frequent unexpected power-cuts there is a possibility of filesystem getting corrupted.

Workaround: Use a Read-Only Root Filesystem.

ELB-561New FeatureU-Boot SPL, Do Not Output Anything on the Debug UARTApalis iMX6, Colibri iMX6BootloaderLowNo

Description: Don't output anything on the debug console unless there is a fatal error. This has been implemented by two defines. The following disables console output in the regular program flow and is enabled in all our configurations: CONFIG_SPL_SILENT_CONSOLE=y The following disables all output on the console and may be enabled by the customer requiring a custom built U-Boot CONFIG_SPL_DISABLE_CONSOLE

ELB-545FixedKernel Boot-up Issue Using PREEMPT_RT with Linux 4.4.21 on Colibri VF61Colibri VF61KernelLowNo

Description: Using PREEMPT_RT patch with Linux 4.4.21 on Colibri VF61 results in a freeze at boot time.

Workaround: Use PMIC integrated RTC for now. Alternatively the mainline Linux kernel already supports the board-level I2C RTC.

ELB-511FixedPCIe Clock and Reset May not Conform to SpecificationApalis T30PCIeLowNo

Description: Our current PEX 8605 errata workaround violates the PCIe clock and reset specification should no PCIe switch be present as e.g. the case on Ixora.

ELB-509FixedeMMC Partition Limited to 4GBApalis T30FlashMediumNo

Description: Currently our update.sh script limits the partition size to around 4GB by default so even after our automatic resizing only 4GB of the 8GB of available eMMC space on the Apalis T30 2GB can be used.

Workaround: Manually modify the EMMC_SIZE calculation for apalis-t30 in our update.sh script. Our upcoming Toradex Easy Installer will no longer suffer from this limitation.

ELB-508FixedUpdate Scripts Limits rootfs Size to around 5GB when using TFTPApalis iMX6, Apalis TK1, Colibri T30, Apalis T30FlashMediumNo

Description: Our current update procedure reads the rootfs payload in pre split files of 64 MB size. The number of chunks is limited to 89 resulting in a maximum size of 5.5 GB.

Workaround: - use the ums command in U-Boot to export the modules eMMC as a mass storage device. - deploy a minimum rootfs and install the 'big' payload after booting into Linux

ELB-507FixedUpdate Scripts Limits rootfs Size to 4GBApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30FlashMediumNo

Description: Our current update procedure requires the rootfs payload to fit in one file on a FAT filesystem. This limits its usable size to 4GB.

Workaround: - use the ums command in U-Boot to export the module's eMMC as a mass storage device - deploy a minimum rootfs and install the 'big' payload after booting into Linux - update over tftp, but see http://developer.toradex.com/software/linux/linux-software/release-details?view=release-roadmap&&issue=21229

ELB-506New FeatureUpdate U-Boot for all Modules to be Based on U-Boot 2016.11 ReleaseColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: Updates our downstream U-Boot to 2016.11. This also includes a newer UBI/UBIFS stack which fixes issues such as "Error reading superblock on volume 'ubi0:rootfs' errno=-22" when using UBI fastmap in U-Boot.

ELB-504New FeatureSODIMM 45 Wake-up uses Pull-up while carrier boards and other modules use Pull-downColibri iMX7GPIOLowNo

Description: The Colibri iMX7 SODIMM 45 wake-up configures an internal pull-up while other modules use pull-down. Also some carrier boards use a external pull-down resistor. Configure an internal pull-down resistor on the pin do be consistent with carrier boards and other modules.

ELB-502FixedUsing Rpmsg Leads to Kernel CrashesColibri iMX7Miscellaneous PeripheralsLowNo

Description: Using rpmsg and exercising the memory subsystem leads to unrecoverable kernel crashes.

Workaround: Use "linux,usable-memory = <0x80000000 0xff00000>;" for iMX 7Solo or "linux,usable-memory = <0x80000000 0x1ff00000>;" for i.MX 7Dual in the device tree memory node.

ELB-497FixedeMMC Partition Limited to 8GBApalis TK1FlashMediumNo

Description: Currently our update.sh script limits the partition size to around 8GB by default so even after our automatic resizing only 8GB of the 16GB of available eMMC space can be used.

Workaround: Manually modify the EMMC_SIZE calculation for apalis-tk1 in our update.sh script. Our upcoming Toradex Easy Installer will no longer suffer from this limitation.

ELB-481New FeatureSupport Basic GPIO Feature on K20 MCUApalis TK1GPIOLowNo

Description: Add support to use signals from the K20 companion MCU connected to the MXM connector as GPIOs. Basic support will be non-interrupt safe (may sleep) and the latency will be similar to regular SPI GPIO expanders.

ELB-475New FeatureRegression: Poweroff when PoweroffColibri VF50, Colibri VF61Kernel, Power ManagementLowNo

Description: The kernel currently does not know a power-off mode which makes the system switch into halt mode. In this mode, the module draws even more power compared to regular power on mode. Implement a power-off mode which switches the SoC into its deepest sleep state.

Workaround: Instead of shutdown (poweroff), use standby or suspend mode.

ELB-467New FeatureMigrate i.MX 6 Products to FSL Community KernelApalis iMX6, Colibri iMX6KernelLowNo

Description: Migrate the kernel used on our i.MX 6 based products to be based on the 4.1-2.0.x-imx branch of the FSL community kernel aka linux-fslc-imx which does already include NXP's latest 4.1.15 2.0.0 GA release changes.

Description: When connecting the module using USB device connection, the module provides an IP address via it's own DHCP server. The DHCP server uses DHCP Option 3 (Router) to announce itself as router which can lead to internet connection interruption on the host.

ELB-434FixedOE Build on Distro with GCC 6 Host ToolchainColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Newer distros like e.g. Fedora 24 use GCC version 6 as the host (native) toolchain. Our jethro based Yocto project build is not able to build the needed native tools, among them the cross compiler on such distros.

Workaround: Use a lightweight container with an older distro as documented on our developer website.

ELB-420FixedMove to GTK+ 3 in Demo ImageColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, GraphicsLowNo

Description: OE migrated the sato image to GTK+ 3. This includes pcman-fm with its libfm. As lxpanel is using libfm we have to follow here or provide our own pcman-fm/libfm recipes. If we move to GTK+ 3 I guess we should do it with all GTK+ based software. e.g all of lxde/lxdm (which may have some issues), the GPIOconfig tool and tegrastats-gtk.

ELB-417New FeatureDistro Boot IntegrationColibri iMX7, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, SDIO/SD/MMC, USBLowNo

Description: U-Boot SPL will greatly improve overall system boot flexibility.

ELB-380New FeatureConsider Using Udisks2Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Udisks development has stalled in 2014, udisks2 seems to be the successor. According to the OE recipes udisks2 also has less dependencies (notable lvm2, which adds almost 3.2MiB to the image and is not commonly used in embedded systems as well as sg3-utils, another 1.1MiB). Udisks2 also has a command line utility see: https://zeth.net/2014/05/28/modern_mounting_with_udisks2.html.

ELB-369New FeatureUpdate BCB to Support Bad Block Markers and Complete PagesColibri iMX7, Colibri VF50, Colibri VF61Bootloader, ConfigBlockLowNo

Description: So far U-Boot writes a BCB (Boot Configuration Block) crafted in a way to work around errata e9609. This also requires the U-Boot to be written in a way which only uses 3/4 of a page (implemented by the writeboot command). This mode has a drawback in practice: It cannot detect bad blocks marked with the usual bad block marker. Colibri iMX7 V1.1B and later do not suffer errata e9609. In order to overcome the limitations of the work-around, new U-Boot version will write the BCB in a new format which allows detecting bad block markers and use complete pages. This also allows to write the boot loader using standard nand write commands.

V2.6.1 Beta 2 (Release date: 2016-11-22)
This is a release for Apalis TK1 2GB V1.1A only. The January 2017 release supporting all platforms (iMX6, iMX7, VFxx, T20, T30, TK1) will follow later as V2.7 Beta 1.

ELB-569FixedUpdate Source MirrorApalis TK1BuildsystemLowNo

Description: As that whole source mirror stuff has been introduced rather haphazardly whoever did that also failed maintaining/updating it since V2.5 e.g. http://sources.toradex.com/V2.5/. The wohle process around this is currently unclear.

Workaround: http://git.toradex.com/cgit/meta-toradex-demos.git/commit/?h=jethro&id=a6c6fa422e9cf9586e0eb8aba40e0460513edf58

ELB-568New FeatureConfigure IPv6-in-IPv4 Tunnel (SIT Driver) as ModuleApalis TK1EthernetLowNo

Description: The IPv6-in-IPv4 tunnel driver creates an additional network interface (sit0). To avoid confusion around that interface and since the sit interface is only used seldom the driver should be made available as a module.

Workaround: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=1cb425d3e668e3d2b77872d5440fffd87ac9cf21

ELB-513New FeatureSupport Apalis UART4Apalis TK1UARTLowNo

Description: Support Apalis UART4.

Workaround: You may find the following commit from our older Linux kernel 3.10.17 as deployed in our embedded Linux BSP V2.4 Beta 1 (May 18, 2015) useful: http://git.toradex.com/cgit/linux-toradex.git/commit?h=toradex_imx_3.10.17_1.0.0_ga&id=82cf64948ddab0360fab876ee321b6191ed7258a

ELB-443New FeatureGCC-6 Usable as the CrosstoolchainApalis TK1, Colibri T20, Colibri T30, Apalis T30KernelLowNo

Description: As OE moves to GCC-6 we should provide our NVIDIA Kernel sources in a way that they can be built with gcc 6. This would allow customers taking our BSP and using it with a later Yocto project release.

ELB-442New FeatureEnable USB OTG Device/Host Detection on USBCColibri iMX7USBLowNo

Description: Automatic USB Device/Host Detection will allow to use the USB port as either Device or Host (OTG). Note: The current default on the USB client port (USBC, OTG) is to be USB host. The reason for this default is that the Colibri iMX7S modules only provide this USB port, and USB host is typically used more often than client.

Workaround: If USB device is preferred as default set the device tree "dr_mode" property of the "usbotg1" node to "peripheral".

ELB-438New FeatureEDID Causing Kernel Panic on T30Colibri T30, Apalis T30HDMI, KernelLowNo

ELB-1431Feature RequestAssess and Generalize Recovery Mode HandlingColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1BootloaderLowNo

Description: Assess and generalize recovery mode handling. Make sure upon recovery mode detection the default U-Boot environment is used rather than the one stored in flash to avoid any bad side-effects. Once U-Boot proper is running automatically start USB fastboot to allow for downloading further parts like e.g. the Toradex Easy Installer ITB.

Workaround: The downstream bring-up i.MX 8/8X/8MM U-Boot already behaves like that and maybe consulted for guidance.

ELB-1419Known IssueParallel RGB Video Playback IssueColibri iMX8XRGB, VGA, Video CodecsLowNo

Description: Parallel RGB which is also what drives the RAM DAC towards the DSI-A or VGA ports on the Colibri Evaluation Board or Iris is using mxsfb-drm which currently fails g2d with the following error:
dpuv1/dpu_lib.c:197 open file error.
g2d_open: Init Dpu Handle fail !
It's currently unknown how one could play hardware accellerated videos without using g2d.

Workaround: Using LVDS or MIPI DSI as available via FFC connector on the back side of the module (e.g. also with the Colibri iMX8X DSI to HDMI Adapter) is using imx-drm which works fine.

ELB-1403Feature RequestAllow I2C Communication in Atomic ContextColibri iMX7Power ManagementLowNo

Description: Kernel warnings can be seen right before the system reboots. This is due to I2C transfers calling the scheduler which is not allowed at this point.

Workaround: So far the warnings have not shown negative effects.

ELB-976Known IssueYear 2038 IssueColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Kernel, Miscellaneous Peripherals, RTCLowNo

Description: On 32-bit systems, Linux uses a 32-bit signed integer type 'time_t' to represent the time at various locations. It gives the time as seconds relative to 1970. The time_t type wraps at "2038-01-19 03:14:07", so all users of time_t likely fail when a type_t instance is set to a timer after that date. This issue is applicable to all 32-bit systems and will be fixed in the mainline eventually.

ELB-496Known IssueTemperature Test on Colibri T20 Uncovered UBI Error When Using bonnie++ With Latest ImageColibri T20FlashMediumNo

ELB-2876Known IssueApalis TK1 V1.2A.003 with Micron eMMC may experience Timeout Errors due to Non-Conformant RPMB AccessesApalis TK1FlashLowNo

Description: Many eMMC devices have a special partition called RPMB (replay protected memory block). Any access to this partition is protected by a OTP key (our modules are shipped with no key, customer can upload one if they choose to use this partition). Access to this partition can only be done using special commands. Our BSP images provide a utility (mmc-utils-cos) which handles read/write/fuse operations for the RPMB. However, due to the way Linux operates we also need to create a device node in devfs. This creates a special file called /dev/mmcblk0rpmb. Since this is a valid device file it may be opened/read/written by any OS utility and such calls will be translated into requests to the eMMC chip. Unfortunately, those would be invalid eMMC requests. And here is where the difference between Micron and Toshiba eMMC parts shows. Toshiba parts answer invalid data reads with zeros while Micron parts ignore them triggering the kernel timeout mechanism. Since the request is invalid both behaviours may be considered valid. However, modules with Micron eMMC parts may experience lengthy delays due to such timeout processing. When accessed correctly (via the mmc utility) the RPMB works correctly in exactly the same way on both vendor's eMMC parts.

Workaround: Applying the following patch avoids experiencing lengthy delays due to such timeout processing: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4e93b9a6abc0d028daf3c8a00cb77b679d8a4df4

Description: Add support for USB Host

ELB-2645Known IssueSoftware Reset does not do a full System ResetApalis iMX8X, Colibri iMX8X, Apalis iMX8SCFWLowNo

Description: A major feature of NXP's BSP L4.14.98_2.3.1_patch was to add support for partition reset. This will reset only a part of the SoC. It does not rerun the ROM so code will not be reloaded. This is the most common way i.MX 8/8X customers do reset as they don’t want the M4 to reset if the AP needs to reset. So software reset will not reboot the whole system anymore, only the AP partition. You can revert this by following below workaround.

Workaround: A complete system reset is still supported. However, the default ATF does a partition reset, not a board reset. It will have to be modified to do a board reset. It will need to call sc_pm_reset() rather than sc_pm_reboot() or sc_pm_reboot_partition(). So from the customer's perspective, this was a change in ATF that they will have to revert. They should be porting ATF for their use case anyway.

ELB-1382Known IssueUHS-I SD Cards May Fail Due to NXP PMIC Errata ER021: VSELECT incorrect set pointApalis iMX8SDIO/SD/MMCLowNo

Description: Note: Apalis iMX8 V1.1A and later do have C silicon or later PMICs which do no longer exhibit this issue and have successfully been validated with various vendor's UHS-I cards to perform at reasonable 85MB/s.

Certain vendors higher-speed UHS-I SD cards may fail due to NXP PMIC Errata ER021: VSELECT incorrect set point. E.g. on SanDisk Ultra or Extreme cards the following may be observed:
[ 290.252408] mmc2: host does not support reading read-only switch, assuming write-enable
[ 290.420738] mmc2: Tuning failed, falling back to fixed sampling clock
[ 290.427228] mmc2: new ultra high speed SDR104 SDHC card at address aaaa

[ 291.095778] FAT-fs (mmcblk2p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

Workaround: Disable UHS-I modes by adding the property no-1-8-v to the affected usdhcX node. - or - Try slower or other vendors SD cards. Eventually, this issue will get fixed in a later NXP PMIC die revision.

ELB-1375Known IssueSlow SATA write operation on larger HDDsApalis iMX6SATALowNo

Description: Some kinds of HDDs can run into a timeout during write operations. The result of the write operation is successful anyway, but it takes a long time to finish. This only occurs when the HDD is connected with SATA and if the particular HDD is one of the affected models.

Workaround: Use another HDD, a USB-to-SATA converter or Torizon. Problem is solved in mainline.

ELB-1351Known IssuePCIe fails randomlyApalis iMX8PCIeLowNo

Description: Currently, PCIe fails. Often with a kernel OOPS backtrace.

Workaround: On the Apalis Evaluation Board, remove the jumper for GPIO7 keeping the PCIe switch in reset.

ELB-1184Known IssueVideo Playback on Parallel RGB Display not Possible Under Certain CircumstancesColibri T30, Apalis T30Multimedia, RGB, USBLowNo

Description: Video playback with nvgstplayer is not working when booted with a plugged-in USB webcam.

Workaround: Plugging-in the webcam after the system booted up may alleviate the issue.

ELB-1183Known IssueBoot Error "commit machine-id"Colibri T20, Colibri T30, Apalis T30KernelLowNo

Description: There may be a boot error reported concerning "commit machine-id". This is caused by an incompatibility between later systemd version and the downstream NVIDIA L4T R16.5 based Linux kernel 3.1.10. However, no further adverse effect has been discovered.

Workaround: Running a mainline based Linux kernel does not exhibit this issue.

ELB-1181Known IssueApalis iMX6 HDMI EDID Not Following SpecificationApalis iMX6HDMILowNo

Description: Apalis iMX6 is not reading the full content of EDID but rather only parts of it. Exact behaviour also depends on the U-Boot environment variable vidargs.

ELB-1180Known IssueApalis iMX6 HDMI EDID Frequency Exceeds 100 kHzApalis iMX6HDMILowNo

Description: The Apalis iMX6 HDMI EDID frequency exceeds the 100 kHz as per specification.

ELB-1176Known IssueWatchdog on iMX7 not Disabled when Pressing the Reset Button (Hard Reset)Colibri iMX7WatchdogLowNo

Description: If the watchdog on Colibri iMX7 gets triggered and the module is reset without power-cycling, then the watchdog does not get disabled. This is due to the errata #e10574 described in Errata NXP Document (https://www.nxp.com/docs/en/errata/IMX7D_2N09P.pdf), which described that the internal watchdog of the i.MX 7 SoC is not working properly. Therefore, the hardware watchdog as integrated in the PIMIC is used on our module to provide the watchdog functionality. Unfortunately, this hardware watchdog can only be reset by a full power-cycle of the module.

ELB-1174Feature RequestBoot Logo not Shown on HDMI OutputApalis iMX6, Colibri iMX6HDMILowNo

Description: When the kernel boots the display shows a boot logo (by default Tux) along with kernel messages.
If one uses the HDMI output that logo is not shown due to the initialization sequence the IPU driver goes through.

Workaround: See: http://www.toradex.com/community/answers/34554/view.html

ELB-1173Known IssueColibri VF50 128MB IT V1.2B May Not Wake-up From Software SuspendColibri VF50Power ManagementLowNo

Description: While the CAN transceiver regulator is properly powered-down on non-use such functionality during suspend is currently missing in flexcan.c.

Workaround: A custom power-down GPIO may be implemented.

ELB-1162Known IssueRegression on Resume With rootfs on NFSApalis iMX6EthernetLowNo

Description: On resuming from a sleep state systemd-journal may hang and print dump messages due to potential slow re-connection to the Ethernet PHY.

Workaround: After resuming the Ethernet PHY may need up to 15 seconds to re-connect its link. After this time, Linux will recover and the module is back to full functionality.

ELB-1161Known IssueSpurious Errors Shown During Legacy Update ProcedureApalis TK1, Colibri T30, Apalis T30BootloaderLowNo

Description: During the legacy update procedure running e.g.:
run setupdate
run update
May show the following spurious errors which can usually be ignored:
MMC read: dev # 0, block # 16383, count 1 ... MMC: block number 0x4000 exceeds max(0x2000)
0 blocks read: ERROR
This has to do with various eMMC parts featuring different eMMC hardware boot area partition sizes which get probed by the legacy U-Boot update scripts potentially showing missleading error messages.

Workaround: Just ignore such error messages during the legacy update procedure.

ELB-1159Known IssueUSB devices fail to initialize through a USB HubColibri iMX7USBLowNo

Description: USB devices don't get properly initialized when connected at boot through a USB Hub (usb usb1-port1: cannot reset (err = -32)).

Workaround: There are several workarounds: 1. Adding 900 ms on the init2 of hub_activate function (drivers/usb/core). 2. Using a direct USB connection (instead of using a USB Hub connection). 3. Wait for Linux to finish booting to connect the USB.

ELB-1157Known IssueSoftware Reset Doesn't Always Work CorrectlyColibri T20Bootloader, KernelLowNo

Description: Some modules sometimes do not boot after a software reset.

Workaround: Triggering a reset via PMIC reliably initiates a hard reset e.g. doing the following from within U-Boot:
i2c dev 0
i2c mw 0x34 0x14 1 0x01

ELB-1040Known IssueAdding Locale and Language to Linux Image Build has no EffectApalis iMX6BuildsystemLowNo

Description: During an Open-Embedded Build, the added locale and language for the system are not included in the final image.

Workaround: Since the value of the variable IMAGE_LINGUAS=“pl-pl en-us” in local.conf is overruled by the value coming from the image recipe, it is not possible to set the needed value from the local.conf. However one can append the language by adding IMAGE_LINGUAS_append = ” pl-pl” in local.conf.

ELB-1025Known IssueNative compilation using arm-angstrom-linux-gnueabi-gcc not working with GCC 7.2 and aboveColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Apalis T30BuildsystemLowNo

Description: Currently native Compilation is not working in the regular Bsp (version > 2.8) due to a mismatch of GCC libraries.

Description: HDMI HDA resp. I2S audio may not work with certain screens depending on available display modes and pixel clock frequencies. HDMI HDA resp. I2S audio may also not work after hot-plugging.

Workaround: Make sure to use vidargs selecting a HDMI audio capable pixel clock frequency. Do not hot-plug resp. power-cycle after plugging in HDMI. If you keep having issues try another brand/model screen.

ELB-1002Known IssueU-Boot Splash Screen Not WorkingApalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: On Colibri T20 and Apalis/Colibri T30 the famebuffer console output is shown rather than an image splash screen due to differences in graphics stacks. On Apalis TK1 there is currently no framebuffer support.

Workaround: You may use a Linux kernel or user space splash screen.

ELB-1001Known IssueOpenCV4Tegra Has Missing Run-Time DependenciesApalis TK1CSI, GraphicsLowNo

Description: OpenCV4Tegra currently may fail due to "run-time" dependencies:
cd /usr/lib/; find . -name 'libopencv*so*' -exec ldd {} + | grep 'not found' | sort | uniq

ELB-990Known IssuePaths in a SDK's qmake Project Include Files are not RelocatedApalis TK1BuildsystemLowNo

Description: If one builds an SDK for Qt5 one gets qmake project include files (*.pri) which contain paths valid for the build host used to compile the SDK rather than paths relocated to where one extracted the SDK to.

Workaround: Fix the paths, e.g. have a look at this community thread: https://www.toradex.com/community/questions/24918/strange-paths-when-installing-angstrom-sdk-for-teg.html

ELB-978Known IssueLegacy Update Procedure May Fail With Bigger ImagesColibri iMX7, Colibri VF50, Colibri T20FlashMediumNo

Description: On NAND flash based modules like the Colibri T20, the legacy update procedure depends on first loading the entire root file system image into RAM. If your custom image is significantly larger than our regular demo images it may no longer easily fit into 256MB of RAM, therefore, failing the legacy update procedure (it may just hang or even crash but definitely fails to update the root file system).

Workaround: Doing the following before 'run setupdate; run update' may help to a certain extend:
setenv fdt_addr_r 0x01000000
However, even bigger images may still fail requiring a different flashing strategy altogether (e.g. initially booting from an initrd or via NFS subsequently updating the root file system from within Linux on-the-fly.

ELB-977Known IssueConcurrent Dual CSI-2 Camera FailingApalis T30CSILowNo

Description: Concurrent dual CSI-2 camera is currently failing on Apalis T30. It is working fine on Apalis TK1.

Workaround: Apalis TK1 would support this.

Description: NXP doesn't provide any support for FreeRTOS and is not writing peripheral drivers for ADC and SPI on Vybrid.

Workaround: FreeRTOS on i.MX 7 provides support for ADC and SPI. It might be taken as a base for a port to Vybrid modules. This has not been verified by Toradex.

ELB-911Known IssuePlaying Wavefile on Apalis T30 using Java makes the Kernel freezeColibri T30, Apalis T30Analog AudioLowNo

Description: This has initially been observed using JDK 1.8.0_121 on our stable BSP 2.6 but the system still does freeze as of JDK 1.8.0_152 on BSP 2.8b3. There seems to be a race condition within the clocking and/or DMA subsystems caused by Java's rather special way of doing ALSA.

Workaround: Playing MIDI files instead seems to work. Alternatively, using the mainline Linux kernel playing a wavefile using the same Java versions also works just fine.

ELB-888Known IssueUnable to control CPUquiet settings on Apalis TK1Apalis TK1KernelLowNo

Description: On Apalis TK1 running 3.10 kernel it's impossible to control CPUquiet using sysfs. CPU on/off schedulesr provided in kernel always operates in automatic mode. CPUquit can be disabled by disabling CONFIG_CPUQUIET_FRAMEWORK and CONFIG_TEGRA_AUTO_HOTPLUG in kernel config (all 4 cores will be permanently active, and low power core will be disabled)

Description: LM816 Wi-Fi speed is limited to 1 Mbit/s rx/tx.

Workaround: Updating to a later Wi-Fi backports may help but only marginally.

ELB-851Known IssueRESET_MOCI is Kept in Reset Until Linux Probes PCIe DriverApalis iMX6, Apalis TK1Bootloader, RGB, USBLowNo

Description: U-Boot does not de-assert the RESET_MOCI signal. RESET_MOCI needs to be pulled during PCIe driver initialization sequence. In order to not reset again during Linux boot we do not de-assert RESET_MOCI in the bootloader. Due to this all components on the carrier board connected to RESET_MOCI are kept in their reset state too. On the Evaluation Board that is notably the USB Hub and a display connected to the Unified Interface Display Connector.

Workaround: One may release RESET_MOCI in the bootloader code if needed. During Kernel boot RESET_MOCI will be asserted again for 100ms during PCIe initialization.

ELB-845Known IssueDisconnecting MIPI CSI-2 Camera May Lead to System FreezeApalis TK1CSILowNo

Description: Disconnecting MIPI CSI-2 camera may lead to system freeze.

Workaround: Make sure your camera sensor provides a continuous data stream or stop the capturing first and then allow unplugging.

ELB-843Known Issue32-bit Deployment Tools Interferes with OpenEmbedded UBIFS Image TypeColibri iMX7, Colibri iMX6ULL, Colibri VF50, Colibri VF61BuildsystemLowNo

Description: When using UBIFS image type the resulting image is not bootable. Systemd fails to mount file systems and ultimately drops into an emergency shell. The reason is that the resulting image has wrong user/group ids assigned to directories and files.

Workaround: The utility mkfs.ubifs is compiled as a 32-bit binary for the legacy image format. Make sure to remove the 32-bit flag by removing meta-toradex-(demos|bsp-common)/recipes-devtools/mtd/mtd-utils_%.bbappend.

ELB-825Known IssueExternal HDA Audio Codec not AvailableApalis TK1Digital AudioLowNo

Description: HDA is currently not supported on the digital audio interface DAP1. Therefore the Realtek ALC898 HD audio codec as assembled on the Apalis Evaluation Board won't work.

Workaround: You may use any Linux supported I2S codec like e.g. the SGTL5000 from NXP (formerly Freescale). Please note that custom software adoptions will be required.

Workaround: Just keep waiting.

ELB-706Known IssueFew Colibri iMX7S Were Delivered With a Constant MAC AddressColibri iMX7EthernetLowNo

Description: In the testing of Colibri iMX7S the U-Boot environment variable 'ethaddr' was set to the value '00:14:2d:12:34:56' and thus cloaking the value set in the configblock. Our test procedure has been updated in order for a regular MAC address being used.

Workaround: Deleting the U-Boot environment variable ethaddr fixes the issue. This can be done by any of the following: 1) flashing an image 2) setenv ethaddr; saveenv 3) env default -a; saveenv

ELB-702Known IssueNTSC Decoding With ACA (ADV7280 Resp. ADV7280-M)Apalis TK1, Colibri T20, Colibri T30, Apalis T30Camera Parallel Interface, CSILowNo

Description: While the ADV7280 as found on our new Analogue Camera Adapter should allow for NTSC decoding it currently seems not to work properly. The same issue has been observed using the CSI version ADV7280-M on Apalis T30/TK1.

Description: The current Ethernet switch implementation does not allow monitoring the external Ethernet ports. Further Linux switchdev subsystem integration would be needed.

ELB-643Known IssueADV7280 Driver Reports Wrong Framerate Due To DeinterlacerApalis iMX6, Colibri iMX6Camera Parallel InterfaceLowNo

Description: The ADV7280 Video ADC used on the Analog Camera Module ACA is capabable of deinterlacing video. In doing so it creates a full frame for each half frame and thus doubles the framerate. When feeding the video stream into gstreamer the original framerate is assumed to still be valid. That will not be noticed if the stream is immediately displayed, however when the stream is recorded in a file the framerate gets wrongly coded and thus the resulting stream runs at 50% of its original speed.

Workaround: Disable the deinterlacer in the driver, recompile and deploy the kernel module. Comment the HW_DEINT macro: http://git.toradex.com/cgit/linux-toradex.git/tree/drivers/media/platform/mxc/capture/adv7280.c?h=toradex_4.1-2.0.x-imx#n118 The following gstreamer pipeline also works as a solution without disabling hardware deinterlace: gst-launch-1.0 -e -v \ imxv4l2videosrc do-timestamp=true crop-meta-x=16 crop-meta-y=16 crop-meta-width=660 crop-meta-height=522 ! \ textoverlay text="Hello_World" shaded-background=1 font-desc="Arial 22px" ! \ tee name=tx \ tx. ! \ vpuenc_mpeg4 bitrate=1000 ! queue ! mux. \ tx. ! \ imxeglvivsink \ alsasrc do-timestamp=true ! audio/x-raw, format=S16LE, rate=44100, channels=2 ! \ imxmp3audioenc bitrate=96 ! queue ! mux. \ avimux name=mux ! \ filesink sync=true location=video.avi

ELB-638Known IssueU-Boot: Certain USB Memory Sticks May Not Work Reliably Behind a USB HubColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: Certain USB memory sticks may not work reliably behind a USB hub. Please note that some (Apalis) if not all (Colibri) USB sockets on our evaluation boards are always behind an on-carrier USB hub.

Workaround: Switch to a different carrier board without an on-carrier USB hub like Iris or Ixora, try a different brand USB memory stick or revert to a completely different update media like an SD card.

ELB-624Known IssueHDMI Hot-Plugging May FailApalis TK1Graphics, HDMI, I2C, KernelLowNo

Description: While HDMI hot-plugging works just fine on the Apalis Evaluation board it currently fails with EDID errors on Ixora. It's related to a voltage level incompatibility on Ixora with Apalis TK1 modules.

ELB-621Known IssueSPI clock not monotonic across two transfersColibri VF50, Colibri VF61SPILowNo

Description: The SPI clock frequency seems not to be monotonic across transfers (e.g. there is a short clock pulse between two subsequent transfers).

Workaround: Set device tree properties fsl,spi-cs-sck-delay and fsl,spi-sck-cs-delay to 100ns and 50ns respectively in dspi device tree node.

ELB-611Known IssueDistro Boot IntegrationApalis iMX6, Colibri iMX6Bootloader, SDIO/SD/MMC, USBLowNo

Description: At least Fedora 25 for ARM currently just hangs upon booting the kernel without any further messages being printed.

ELB-602Known IssueColibri T30 May Freeze on Concurrent SD Card and Multiple USB Devices Stress TestingColibri T20, Colibri T30, Apalis T30SDIO/SD/MMC, USBLowNo

Description: In use cases involving all 3 USB host controllers with USB hubs connected to the OTG as well as the regular host port with USB keyboard/mouse resp. USB-to-serial-adapter connected plus an SD card the Colibri T30 may freeze upon stress testing.

Workaround: Only use two USB host controllers. Ethernet already uses one of them. Use an external USB hub for further USB ports.
Alternatively if you don't use Ethernet you may disable it as follows: 'echo 0 > /sys/class/gpio/gpio232/value'.
We didn't see these issues when using mainline.

ELB-587Feature RequestSupport SD UHS mode (new feature of Colibri iMX6 V1.1)Colibri iMX6SDIO/SD/MMCLowNo

Description: Add support for SD UHS (1.8V) which is possible with V1.1 of the Colibri iMX6.

Workaround: The following commit for BSP 2.6 introduces an optional SD_1_8 define for enabling UHS-I support:
http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_imx_3.14.52_1.1.0_ga&id=7659fe414d37861050ec909bb2d27c4bfca87d27
Please note that all Toradex carrier boards by default use 3.3 volt pull-up resistors on resp. signal pins which would need removing as well.

ELB-575Known IssueLX Panel, CPU Usage Monitor & Confusing Display Due to Dynamic Full ScaleApalis TK1, Colibri T30, Apalis T30CPULowNo

Description: The LX Panel gives an overview of the current CPU Usage by providing a rolling chart of the last minute. Full Scale of the chart is what all the CPU cores which are currently on could compute at the current CPU speed. Since the CPU speed adapts to the current workload full scale is not a constant. On top of that on some modules CPU cores are dynamically switched on or off depending on the current computing load. This can lead to the confusing effect that increasing the load by a little can lead to a decreased load displayed in the 'CPU Usage Monitor' because on additional core is switched on.

ELB-571Known IssueMemory Corruption with ext4 FilesystemColibri T20, Colibri T30, Apalis T30Flash, Kernel, SATA, SDIO/SD/MMC, USBMediumNo

Description: NVIDIA's downstream L4T kernel our BSPs are based on has issues with the ext4 file system.

Workaround: Use the ext3 file system instead.

ELB-566Known IssueGPIO interrupts do not work on Cortex-M4 after Linux bootColibri iMX7GPIOLowNo

Description: If a GPIO bank is assigned to Linux (defined in the device tree), the driver masks and clears all GPIO interrupts on startup. If a GPIO of the same bank is used as a interrupt source on the Cortex-M4 core, the interrupts will not work after Linux started. If the M4 enables an interrupt after Linux started, Linux will receive that interrupt too and mask the interrupt again (since from a Linux perspective, the interrupt is not enabled).

Workaround: Disable a GPIO bank in the device tree to assign it exclusively to the Cortex-M4 core.

ELB-560Feature RequestU-Boot SPL Does Not Go to Recovery Mode If No Bootloader Is FoundApalis iMX6, Colibri iMX6BootloaderLowNo

Description: If the SPL can't load the bootloader it currently prints a message and hangs. Change that to print a message and start in Recovery Mode, aka. Serial Download Mode.

Workaround: Go manually into Recovery Mode. Refer to the modules data sheet for possible procedures.

ELB-557Known IssueImplement workaround for unstable 500MHz clock errata (e6235)Colibri VF61CPULowNo

Description: Due to a chip errata the main CPU clock may be unstable. During our extensive testing We have not observed issues with our design so far. We never saw any problem and also don't have any negative customer feedback.

ELB-554Known IssueExar PCIe UART driver does not work on Apalis T30Apalis TK1, Apalis T30PCIe, UARTLowNo

Description: Exar PCIe UART driver backport (or official Exar driver) does not work on Apalis T30

ELB-550Known IssueI2C6 on Apalis TK1Apalis TK1I2CLowNo

Description: I2C6 as available on Apalis TK1 MXM3 pins 71/73 aka DP_AUX_CH0_N/P is currently not supported.

ELB-542Feature RequestARM DS MDK Linux Kernel DebuggingColibri iMX7Buildsystem, Miscellaneous PeripheralsLowNo

Description: ARM DS MDK requires a special set of Linux kernel configuration options in order to allow for debugging the Linux kernel (incl. modules) and FreeRTOS side by side. Unfortunately some of those required configurations are unsuitable for our regular BSP plus one anyway needs the full debug symbol for any real debugging.

Workaround: Please enable the following Linux kernel configuration options: CONFIG_DEVKMEM, CONFIG_DEBUG_INFO, CONFIG_PROFILING, CONFIG_FTRACE and CONFIG_ENABLE_DEFAULT_TRACERS. Then disable this option: CONFIG_CPU_IDLE. Now re-compile as explained in the following article on our developer website: http://developer.toradex.com/knowledge-base/build-u-boot-and-linux-kernel-from-source-code

ELB-540Known IssueSome USB Thumb Drives don't Work Well in U-BootApalis iMX6, Colibri iMX6Bootloader, USBLowNo

Description: Use these results in load errors when copying large files, e.g. once used for image update.

Workaround: Find one that works for you. All USB SD card readers we tried so far worked.

ELB-539Known IssueFirst Boot, Rootfs Expansion Affects System PerformanceApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30FlashMediumNo

Description: On first boot the rootfs partition gets expanded to the full size of the partition it lives in. This resizing process adversely affects system performance for the first few minutes until completed. Compare with: http://git.toradex.com/cgit/meta-toradex-bsp-common.git/tree/recipes-core/fs-init

ELB-538Known IssueUSB Hub on Evaluation Board not Enabled in U-BootApalis iMX6Bootloader, USBLowNo

Description: USB hub on Evaluation Board not enabled in U-Boot.

Workaround: Use USBH3 or USBH4 if you need a USB host in U-Boot.

ELB-536Known IssueNo Backlight PWM on V1.0 HWApalis iMX6PWMLowNo

Description: There is no backlight PWM on V1.0 HW. The pin can be used as a backlight GPIO to switch between off and on.

ELB-535Known IssueX11 can only use one ScreenApalis iMX6, Colibri iMX6DSI, Graphics, HDMI, LVDS, RGB, VGALowNo

Description: The Vivante X driver can only make use of the first framebuffer /dev/fb0 while the others can be used through the fbdev framebuffer interface.

ELB-534Known IssueOn some Monitors HDMI EDID is ProblematicApalis iMX6, Colibri iMX6Graphics, HDMILowNo

Description: On some monitors HDMI EDID does not negotiate correct timings.

Workaround: Adding/removing mxc_hdmi.only_cea=1 to the kernel command line may help.

ELB-533Known IssueMic Input not Hot-PluggableApalis iMX6, Colibri iMX6Analog AudioLowNo

Description: Hot-plugging a microphone can reset the audio codec. The driver is not able to bring up the codec again after such an event. This is fixed in Apalis iMX6 V1.1 and will be fixed in Colibri iMX6 V1.2.

Workaround: Not hot-plug the microphone or rebooting fixes the issue. Having a 100 Ohm resistor in series to the microphone on a carrier board makes the module mic hot-pluggable.

ELB-532Known IssueHDA Audio not AvailableApalis iMX6Digital AudioLowNo

Description: The i.MX 6 SoC does not feature HDA audio functionality. Thus the HDA codec on the Apalis Evaluation Board can not be used.

Workaround: If a audio codec needs to be connected you could use I2S and AC97. Refer also to: http://developer.toradex.com/software/linux/linux-software/release-details?view=release-roadmap&&issue=21313

ELB-531Known IssueUART Control Signals DCD/DSR/DTR/RI not workingApalis iMX6, Colibri iMX6UARTLowNo

Description: The UART DCD/DSR/DTR/RI signals are not integrated into the driver.

Workaround: Configure them to be GPIO and read/set them from userspace.

ELB-530Known IssueIrDA not ImplementedColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30IrDALowNo

Description: IrDA requires specially modulated UART signals. While at least some of the UART drivers can be compiled or configured to use IrDA we didn't test if this would actually work.

ELB-529Known IssueU-Boot: USB OTG Port is Always ClientApalis iMX6, Colibri iMX6Bootloader, USBLowNo

Description: In U-Boot the USBO1 and USBC ports for Colibri and Apalis respectively are configured to be client only.

ELB-526Feature RequestSGTL5000 Audio Multi Instance Codec DriverApalis TK1, Colibri T30, Apalis T30Analog AudioLowNo

Description: The SGTL5000 driver in the Linux Kernel currently only supports one codec. The driver would need amending so that multiple codecs can be used. The issue is the statically created VDDD_LDO regulator.

ELB-525Feature RequestAdd support for DSI DisplayApalis iMX6DSI, GraphicsLowNo

Description: The i.MX 6 MIPI DSI interface is available on type specific pins. Setup HW on those pins and bring up the DSI interface.

Workaround: The DSI interface is expected to work, however it has not yet been tested.

ELB-510Known IssueGstreamer Video Playback Segmentation FaultApalis TK1Video CodecsLowNo

Description: While gstreamer video playback works fine it segmentation faults at the very end as follows: Caught SIGSEGV exec gdb failed: No such file or directory Spinning. Please run 'gdb gst-launch-1.0 889' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.

Workaround: Just Ctrl-C the gstreamer process as indicated.

ELB-503Known IssueColibri Evaluation Board: USB 3.0 Devices Plugged in at Boot Time is not AccessibleColibri iMX7USBLowNo

Description: On the Colibri Evaluation Board V3, a USB 3.0 device plugged in at boot time is not accessible after boot. Furthermore, the device seems to influence the on-board USB hub in a way that any USB port 1-4 won't work anymore.

Workaround: Using a regulator in the device tree to toggle the reset of the external USB hub might help avoiding the issue, see https://community.nxp.com/thread/335298.

ELB-487Feature RequestImplementing Linux Serial Driver using K20 UARTsApalis TK1UARTLowNo

Description: K20 MCU has multiple UART peripherals. Special driver integration would allow to use them as serial ports from Linux running on TK1.

ELB-463Known IssueSPDIF not WorkingColibri T20, Colibri T30, Apalis T30Digital AudioLowNo

Description: SPDIF is not working in the V2.6 beta 2 release. This is a regression against older releases.

ELB-458Known IssueConnected SDCard Prevents U-Boot from entering Recovery ModeColibri iMX7, Colibri iMX6Bootloader, SDIO/SD/MMCLowNo

Description: When one wants to enter recovery mode, aka serial download mode, that mode is not correctly working when a SD/MMC card is connected on the SD1 interface, e.g. the SD slot on the Evaluation Board. Symptoms: If the SD card is flashed with an U-Boot the module does not enter recovery mode at all but tries to load said U-Boot. On i.MX6, even if the SD card is not flashed with U-Boot the module does fail when downloading DCD data over USB.

Workaround: Remove any SD card from your system during power cycle / reset when you intend to enter recovery mode.

ELB-452Known IssueUSB OTG on Aster, Orchid, Viola Need USB_P_EN# for Host RoleColibri iMX7, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30USBLowNo

Description: On Aster, Orchid and Viola the USB power enable pin (SODIMM 129) is used for both USB ports USBC and USBH. For all modules but the Colibri iMX7S the Linux kernel controls the USB Power Enable only from the USBH port driver. Thus USBC will be non functional if used as a USB Host when the USBH port is disabled in the kernel (i.e. in the device tree for newer or in the platform data for older kernels). Note that on the Evaluation Board and on Iris the USB Power gets enabled when a USB OTG kabel gets connected.

Workaround: Do not disable the USBH port or change the kernel in a way that the USB Power Enable is controlled by the USBC port as well.

ELB-433Known IssueSuspend/Resume does not Work with PCIeApalis iMX6PCIe, Power ManagementLowNo

Description: Suspend/Resume does not work if a PCIe device has been found. e.g. if 'lspci' returns at least one device. Symptom is that resume blocks after all CPUs have been brought up.

ELB-419Feature RequestLVDS Channel ConfigurationApalis iMX6LVDSLowNo

Description: Starting with Apalis_iMX6_LinuxImageV2.6Beta2 the display timings and resolution can be set from the kernel command line or from the device tree. However the LVDS channel configuration can only be set from the device tree. Implement a command line parameter to bring back this functionality similar to the ldb=xxx parameter from the 3.10.17 kernel. Single/Dual channel. Colour Depth and mapping.

Workaround: Change the device tree according to the needed LVDS configuration.

ELB-408Known IssueUART Overruns When Using DMAApalis iMX6, Colibri iMX6UARTLowNo

Description: The UART may overrun when using DMA. We were not able to reproduce this issue which was reported by a customer.

ELB-407Known IssueBusybox and UTF-8 Chars in FilenamesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: For many utils (e.g. ls) we use busybox in our image. These utils in the used busybox version display chars outside of the 7 bit ASCII range as a '?' even if the locale is set correctly and the system uses e.g. UTF-8.

Workaround: Just enable UNICODE in the BusyBox configuration and re-compile.

ELB-399Known IssueGstreamer/Nvgstplayer Memory LeakColibri T30, Apalis T30Multimedia, Video CodecsLowNo

Description: Each iteration of a movie H264 playback using gstreamer/nvgstplayer allocates a queue via NvMMQueueCreate(phQueue=0x4225f318, max_entries=32, entry-size=224, thread_safe=1) inside NVIDIA's binary only libnvmm_utils.so library which is never freed (such a function creates three pointers of total size 7392 + 28 + 32). Most probably there is a missing NvMMQueueDestroy() somewhere in the decoder handling.

Workaround: The easiest workaround would be to spawn a new gstreamer process for every movie being played as destroying that process after the playback will explicitly free any memory even if not previously implicitly having been freed. Alternatively our partner Antmicro hacked up a custom libnvmm_utils.so wrapper library to be loaded by LD_PRELOAD which may intercept NvMMQueueCreate() calls and adaptively revert to a static queue in order to prevent any memory leaks. While such a solution will of course be highly use-case dependant it should fully fix any leaking. Further investigation on NVIDIA's side is pending.

ELB-392Feature Requesti.MX 6 Thermal ThrottlingApalis iMX6, Colibri iMX6CPU, Temperature SensorLowNo

Description: When the measured SOC temperature reaches /sys/devices/virtual/thermal/thermal_zone0/trip_point_0_temp (currently set to 85°C) the GPU frequency is reduced to 1/64 of its normal value. Once the SOC cooled down to 75°C the clock is set back to 64/64. Should the temperature reach trip_point_1_temp (105°C) the OS is shut down. - Implement a gradual reduction of GPU performance when trip_point_0_temp is reached. - Increase trip_point_0_temp for Industrial Graded products.

Workaround: Set the GPU clock for higher temperatures to something higher than 1/64 in /sys/bus/platform/drivers/galcore/gpu3DMinClock for a trade off of higher performance vs. lower power dissipation.

ELB-386Feature RequestUse Ethernet PHY Power Down Mode for Suspend ModeColibri VF50, Colibri VF61EthernetLowNo

Description: With #16470 the Ethernet PHY power down mode has been disabled. This increased the power consumption during suspend. Since Ethernet is often not used on power constrained devices, we prefer lower power consumption over working Ethernet. Therefor we should reenable the PHY power down mode when using suspend.

Workaround: Use U-Boot's MII capability to put the PHY into sleep mode at boot time (use "mii write 0 0 0x3800" to set PHY's PDOWN mode).

ELB-367Known IssueRare Kernel Panic While Using RNDIS USB GadgetColibri VF50, Colibri VF61USBLowNo

Description: In USB device mode using RNDIS on Vybrid with Windows as host might result in a kernel crash during continuous bi-directional data transfer.

ELB-338Feature RequestLinux Kernel Splash Screen Doesn't Work on HDMI OutputApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T20, Colibri T30, Apalis T30HDMILowNo

Description: Using a Linux logo be it the penguins or a custom one as e.g. explained at http://developer.toradex.com/knowledge-base/splash-screen-linux does not work on the HDMI output. When the kernel sets up the display driver it first sets up VGA resolution subsequently doing DDC/EDID and then sets the final resolution. While the Logo is drawn during the VGA resolution setting it is lost later on.

Workaround: On Apalis/Colibri iMX6 one may use the U-Boot splash screen on HDMI output as well.

ELB-328Known IssueHDMI Violation on 720x480p 16:9Apalis iMX6, Colibri iMX6HDMILowNo

Description: At 720x480p resolution the 'AVI Information Frame' might inadvertently report an aspect ratio of 4:3 even though 16:9 is in effect.

ELB-314Feature RequesteCos Freeze/MCC LockupColibri VF61CPU, KernelLowNo

ELB-313Known IssueIncompatibility Between L4T Linux Kernel and iproute2-ss140804Colibri T20, Colibri T30, Apalis T30CANLowNo

Description: There exists an incompatibility of sorts between the older L4T Linux kernel version our Tegra BSPs are based on and the newer iproute2-ss140804 from our V2.4 BSPs leading to errors as follows:
root@apalis-t30:~# ip -details link show can0
RTNETLINK answers: Invalid argument
Cannot send link get request: Invalid argument

Workaround: Either downgrade to iproute2-ss131122 from our V2.3 BSPs or simply drop specifying a particular interface (e.g. use 'ip -details link show' instead).

ELB-311Feature RequestSupport Cryptographic Acceleration and Assurance Module (CAAM)Colibri VF50, Colibri VF61Miscellaneous PeripheralsLowNo

Description: The CAAM module offers features such as cryptographic authentication (hashing/MACs), symmetric key block ciphers such as AES, DES and 3DES, and random number generation.

Workaround: Use cryptography libraries which implement the algorithms in pure software (such as OpenSSL).

ELB-298Known IssueAudio Capture Stereo IssueColibri T20Analog AudioLowNo

Description: Xinput-calibrator may fail when axis are swapped. Usually a single axis swapped works however when there are multiple ones swapped the algorithm may fail getting any useful calibration coefficients.

Workaround: Avoid swapped axis e.g. by fixing the hardware wiring or pre-configure them via e.g. /etc/X11/xorg.conf as follows:
Section "InputClass"
    Identifier    "ResistiveTouch"
    MatchProduct  "stmpe-ts"
