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 in 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 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.

Issue #StatusSubjectModuleSubsystemSeveritySubmitted for Mainline

5.4.0 (Release date: 2021-09-30)
Embedded Linux BSP Q3 2021 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-4-0-quarterly
ELB-4043FixedLatest CMA Configuration MAX(256MB, 25% of MEM) Not Working on 8GB SKU 0066Verdin iMX8M PlusKernelLowNo

Description: Unfortunately, CMA needs to be in low memory and to be consecutive is not allowed to cross any other reserved sections. This severely limits its maximum available size and it looks like there is no consecutive 2GB block available that would meet all these conditions.

Workaround: Luckily, one may simply override the amount of CMA via Linux kernel command line parameter. E.g. for the BSP:
setenv setup 'setenv setupargs console=${console},${baudrate} console=tty1 consoleblank=0 earlycon cma=1376MB'
saveenv; boot
Or in the Toradex Easy Installer case:
setenv teziargs cma=1376MB; saveenv; boot

ELB-4006New FeatureUpdate Downstream Kernel To L5.4.70_2.3.3 Patch ReleaseVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis iMX8KernelLowNo

Description: Update to latest kernel.org patch release and pull in latest patches from linux-imx 5.4.70_2.3.3 patch release.

5.3.0 (Release date: 2021-07-08)
Embedded Linux BSP Q2 2021 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-3-0-quarterly
ELB-4019New FeatureCMA Memory Too Large on Certain SKUsVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Apalis iMX8KernelLowNo

Description: CMA memory allocation is a fixed value and takes up too much space on certain SKUs. Drop the configuration of the CMA in the device tree in favour of specifying it in the kernel config with a size of 256MB or 12% of total memory which ever is less.

ELB-3958New FeatureUpdate Linux Kernel to NXP BSP Patch L5.4.70_2.3.2Verdin iMX8M PlusBuildsystem, KernelLowNo

Description: Integrate all the changes into linux-toradex kernel which were released in NXP L5.4.70_2.3.2 patch release.

ELB-3957New FeatureUpdate Meta-Toradex-NXP to NXP BSP Patch L5.4.70_2.3.2Verdin iMX8M PlusBuildsystem, KernelLowNo

Description: Integrate all the changes into our buildsystem/userspace which were released in NXP L5.4.70_2.3.2 patch release.

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-3505New FeatureBring-Up Verdin iMX8M Plus V1.0BVerdin iMX8M PlusBootloader, KernelLowNo

Description: Add support for the new Verdin iMX8M Plus V1.0B in a way that it at least boots and is on the same level of support as before the V1.0A module

ELB-3326New FeatureRebase Downstream Kernel on NXP L5.4.70-2.3.0 ReleaseVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis iMX8KernelLowNo

Description: Update Linux kernel to new NXP L5.4.70-2.3.0 release.

5.1.0 (Release date: 2020-12-30)
Dunfell Q4 2020 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-1-0-quarterly
ELB-3209New FeatureMust Have: Linux KernelVerdin iMX8M PlusKernelLowNo

Description: Add initial support for Linux kernel.

ELB-3035New FeatureDrop defconfigs in OE Meta-DataVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8Buildsystem, KernelLowNo

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.

Not Planned
ELB-3848Known IssuePWM Instance Number Depend on Device Tree OverlaysVerdin iMX8M Plus, Verdin iMX8M MiniKernelLowNo

Description: PWM_1 and PWM_2 gets its pwmchip instance number changed when turning on or off the HDMI overlay.

Workaround: Use a fixed Device Tree for production images according to https://developer.toradex.com/device-tree-customization. This way the issue will not appear.
