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.

5.2.0 (Release date: 2021-04-08)
Embedded Linux BSP Q1 2021 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-2-0-quarterly
ELB-3499New FeatureApalis iMX8 Images Additionally Contain Apalis iMX8X OverlaysApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusDevice TreeNo

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.

Workaround: Remove the "license" line in the image.json file.

ELB-3475New FeatureChange recipes to fetch from https instead of gitApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemNo

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-3337New FeatureConsistent /boot Mounting if Booting From SD Card or USB Memory StickApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusFlashNo

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: Update all components of userspace according to the release notes of the new NXP L5.4.70-2.3.0 release.

Description: Add missing display device tree overlays.

ELB-3197New FeatureWIC Images do NOT Contain Device Tree OverlaysApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusDevice TreeNo

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

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 unified /dev/apalis-emmc symlinks for fw_env.config so we only need one config for all modules.

ELB-3250New FeatureMount Separate FAT Boot Partition to /bootApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusFlashNo

Description: Make sure the boot partition on eMMC-based modules is mounted consistently across all modules to /boot.

ELB-3195FixedDrop ptest From DISTRO_FEATURESApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemLowNo

Description: Drop ptest from DISTRO_FEATURES. This should reduce total packages that have to be built.

ELB-3188FixedCorrupted Build Info in U-BootApalis iMX8, Apalis iMX8X, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBootloaderLowNo

Description: NXP i.MX 8QXP/8QM-based modules the buildinfo shows some garbage instead of IMX-MKIMAGE version used.

ELB-3181FixedLPSPI Occasionally Receives Wrong DataApalis iMX8, Apalis iMX8X, Colibri iMX8XSPILowNo

Description: LPSPI occasionally receives wrong data.

Workaround: NXP’s L5.4.47-2.2.0 release seems to have this fixed on their i.MX 8QuadXPlus Multisensory Enablement Kit (MEK).

ELB-3082New FeatureUpdate Knowledge Base ADC ArticleVerdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8Analog InputsNo

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-3003FixedMwifiex: Invalid Sched_Scan ParametersApalis iMX8, Apalis iMX8X, Colibri iMX6ULL, Colibri iMX8X, Verdin iMX8M MiniWi-FiLowNo

Description: When using the on-module Wi-Fi "Invalid Sched_scan" message appears. This error message has no meaning in our use-case so we removed it.

ELB-2975New FeatureDistroboot DHCP Boot Requires New Format of Scripts to Make it FunctionalApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBootloaderNo

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

ELB-2606Feature RequestAdd Support for Apalis iMX8X V1.1B and Colibri iMX8X V1.0C with i.MX8QXP C0 and PF8X00 C1Apalis iMX8X, Colibri iMX8XBuildsystemNo

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.

ELB-2528Feature RequestAdd MXM3 Names to the Module-Level Device Tree for Apalis iMX8XApalis iMX8XNo

Description: Add MXM3 names to the module-level device tree.

Description: The fw_setenv config file uses a hardcoded device file for where the U-Boot environment can be found. (mostly /dev/mmcblk0boot0. Depending on the kernel version the device number might change. Generalize this so that fw_printenv/fw_setenv finds the U-Boot environment independent on how mmc gets enumerated.

ELB-1278Known IssueSPI CS When Using DMAApalis iMX8X, Colibri iMX8X, Apalis iMX8SPILowNo

Description: It’s a limitation that one cannot use native SPI CS & DMA and have a continuous CS for the whole transfer. The CS is deasserted after each word sent.

Workaround: Either use the driver in PIO mode or use GPIO CS if using DMA. To use the driver in PIO mode, in the device-tree override the dma-names property, i.e. with 'dma-names = "no","no";'

ELB-4083Known IssueStop PCIe Endpoint Results in WarningApalis iMX6, Apalis iMX8, Apalis iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusPCIeLowNo

Description: After an endpoint is started through configfs, if 0 is written to the configfs entry 'start', the controller stops but the epc_group->start value remains 1.

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.
