BSP Layers and Reference Images for Yocto Project Issue Tracker

 

The following table contains known issues, scheduled bug fixes, and feature improvements for the Toradex BSP Layers and Reference Images for Yocto Project.

The tickets are split into two major states:

  • Submitted (open): new features and bug fixes for BSP versions that have not yet been released. They may be scheduled for a specific release version; not planned; or in our backlog. All of them have one of the following states:
    • Known Issue: a bug or unexpected behavior that has been reported and is pending a fix. Once fixed, the status will transition to Fixed.
    • Feature Request: a new feature that may be added to a future release. Once released, the status will transition to New Feature.
  • Released (closed): new features and bug fixes for BSP versions that have already been released. All of them have one of the following states:
    • Fixed: a bug that has been fixed and released.
    • New Feature: something that didn't exist before and was added to a new release.


Any schedules are not guaranteed but reflect the current planning. The planning could be shifted due to priority changes.

Issues that are scheduled for a specific version will be integrated into the mentioned version of the BSP.

We will update this table continuously in order to always provide the latest state of our development plan. Please see also the Linux Support Strategy to learn more about the different releases.

Description: Add device trees for all SKU variants and Carrier Boards of the Colibri family.

ELB-1419FixedParallel RGB Video Playback IssueColibri iMX8XRGB, VGA, Video CodecsLowNo

Description: Parallel RGB which is also what drives the RAM DAC towards the DVI-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 accelerated 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.

Description: An image for Apalis iMX8 contains in addition to the ones specific to Apalis iMX8 the specific ones for Apalis iM8X. While this does not hurt it might be confusing.

Workaround: -

ELB-3485New FeatureAdd EULA License Accept Window When Installing an Image Using the Toradex Easy InstallerApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemNo

Description: Show EULA license on tdx-reference images that has to be accepted when installed with the Toradex Easy Installer. Note that our tdx-reference images can no longer be installed unattended using the Toradex Easy Installer.

Description: Change OpenEmbedded recipes from Toradex to fetch from https instead of git where possible.
In an approach to make it more user-friendly, especially for big company customers that do not allow git-protocol in their networks we decided to use https as a fetching source.
We are aware that we cannot do this for each and every layer but at least for ours we decided to switch from git to https.

ELB-3401New Featurespidev Disabled by Default, Overlay to Enable itColibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8XDevice Tree, SPINo

Description: Add device tree overlay to disable mcp251x spi-to-can transceiver and enable spidev.

Description: Due to the class "classes/image_type_tezi.bbclass" in "meta-toradex-bsp-common" setting the label to all upper-case "BOOT", and WIC images using all lower-case "boot", the /boot mounting may actually not work at all (given that an image got actually installed to eMMC using the Toradex Easy Installer prior to distrobooting from SD card and/or USB memory stick). However, rather than having the eMMC's boot partition mounted to /boot it would make much more sense to mount the resp. boot media's boot partition there.

ELB-3327New FeatureUpdate Userspace to NXP L5.4.70-2.3.0 ReleaseApalis iMX6, Apalis iMX8, Apalis iMX8X, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemNo

Description: WIC images do not contain the device tree overlays. This affects users that boot from the SD card or USB sticks. See Boot From an SD Card / USB Stick / SATA drive for reference.

Workaround: Manually deploy them. See how-to on Deploying a Device Tree Overlay.

ELB-2710New FeatureDrop fdt_fixup and Clean-up DocumentationApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M MiniBootloaderNo

ELB-3322New FeatureWIC Images May Fail Mounting /bootApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusFlashNo

Description: WIC images fail mounting /boot. Looks like classes/image_type_tezi.bbclass in meta-toradex-bsp-common is setting the label to all upper-case BOOT while WIC images are using all lower-case boot. This is particularly bad on Verdin iMX8M Plus as due to no Toradex Easy Installer being available as of yet we are using WIC images with the bmap tool for production flashing.

ELB-3293New FeatureMake /etc/fw_env.config Unaware of Used Block Device InstanceApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBootloader, BuildsystemNo

Description: Use KBUILD_DEFCONFIG in OpenEmbedded to define the defconfig to build the kernel from. Toradex is now using the defconfigs from the kernel-repo instead of providing separate defconfigs in OpenEmbedded. However if you wish to provide your own defconfig in OpenEmbedded you can still do so.

ELB-3026New FeatureMake Thermal Sensors Work WellColibri iMX8XTemperature SensorNo

Description: Add back the support for thermal sensors on new 5.4.x-2.1.0 kernel.

ELB-2949New FeatureChange *_defconfig and ${board} Names in U-BootApalis iMX8, Apalis iMX8X, Colibri iMX8X, Verdin iMX8M MiniBootloaderNo

Description: Some defconfig and board names have changed with the move the later 2020.04 U-Boot as we did not mainline it the same way as it was in the downstream U-Boot. Let us clean this up and only use proper Toradex product names e.g. apalis-imx8, apalis-imx8x and colibri-imx8x.

ELB-2891New FeatureDrop BackportsApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M MiniKernelNo

Description: With the move to the NXP L5.4.24-2.1.0 BSP we will have all our downstream and mainline/upstream Linux kernels based on 5.4. Using 5.4 based backports with this does not make any sense so drop it.

ELB-2875New FeatureChange U-Boot Splashscreen to Default to DisabledApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M MiniGraphicsNo

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.

Description: When using the “fsl,imx6sx-lcdif” (ADMA LCDIF DPI Interface) driver and playing a video, using the GPU, or having some high memory load some display artifacts can happen because of bandwidth issues. This is not happening with 800x600 resolutions or lower.

Workaround: Use DPU ( "fsl,imx-lcdif-mux-display" driver, display_lcdif) as a display controller or Use a 16-bit frame buffer (e.g. `gbm-format=rgb565` in weston.

ELB-5123Known IssueKernel Error: `phy-xxx.dphy.x: Invalid CM/CN/CO values` while using MIPI-DSI to HDMI bridgeColibri iMX8XDSILowNo

Description: We get these error because some HDMI modelines have a target clock that lead to invalid DSI clock configuration. These modelines are not usable and they are not shown using modetest tool.

Description: `fdtfile` variable always takes precedence over `fdt_board`

Workaround: From U-Boot, use the following commands to properly use the `fdt_board` variable: ``` setenv fdtfile setenv fdt_board ${carrier_board} # e.g. setenv fdt_board dahlia saveenv reset ``` replacing `${carrier_board}` with the actual carrier board name according to the dtb filename.

ELB-4802Known IssueXDG Base Directory Specification Not Implemented Over SSH LoginsApalis iMX6, Apalis iMX8, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemLowNo

Description: With some external hardware combinations, the user could experience significant boot delays that are connected to the systemd-udev-settle.service being selected as a dependency for the rngd.service startup. One example of a hardware that could present this behavior is 3G modems.

Workaround: Masking the systemd-udev-settle.service should be enough to get boot times back to normal. Keep an eye on failures to start up the rngd.service as it depends on devices to be present when initialized.

ELB-4606Known IssueLVDS Display Not Working Out-Of-The-Box on IrisColibri iMX8XLVDSMediumNo

Description: Provide proper vidargs for mainline 5.4 in BSP 4.0.0

ELB-2645Known IssueSoftware Reset does not do a full System ResetApalis iMX8, Apalis iMX8X, Colibri iMX8XSCFWLowNo

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-2600Feature Request[U-Boot][mainline] Sync U-Boot DTS with the Linux mainlineApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis T30, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Colibri T20, Colibri T30, Colibri VF50, Colibri VF61Bootloader, Device TreeNo

Description: Adjust ADV7280 driver so it works with parallel camera interface as found on Apalis/Colibri iMX8X as well.

Workaround: Use MIPI-CSI instead of parallel CSI

ELB-1397Known IssueRS485 RTS line gets pulled low on ioctlApalis iMX8X, Colibri iMX8X, Apalis iMX8UARTLowNo

Description: When using RS485 feature, the RTS line gets pulled low about 100us when acessing ioctl(). That means also that RTS gets pulled low for 100us when opening the respective tty.

Workaround: During initialization of RS485 the PADs could be muxed to GPIO and afterwards be muxed back in order to prevent interference with other bus participants.
