Known Issues and Limitations in Scarthgap (5.0.16)

Upstream

• See https://git.yoctoproject.org/poky/tree/documentation/migration-guides/release-notes-5.0.16.rst?h=scarthgap#n20 CVE patches are applied by the YP community.

• Scarthgap 5.0.16 tag commit id is https://git.yoctoproject.org/poky/commit/?h=yocto-5.0.16&id=1d54d1c4736a114e1cecbe85a0306e3814d5ce70 which matches Xilinx/poky at xlnx-rel-v2026.1 tag commit id but the DISTRO_VERSION is still pointing to 5.0.15 poky/meta-poky/conf/distro/poky.conf at xlnx-rel-v2026.1 · Xilinx/poky The observed mismatch between the yocto-5.0.16 tag and DISTRO_VERSION (still 5.0.15) is a known upstream Yocto issue in scarthgap 5.0.16. The release tag was created without updating the DISTRO_VERSION field. This is cosmetic and does not impact build outputs. A fix exists upstream and can be cherry-picked https://git.yoctoproject.org/poky/commit/meta-poky/conf/distro/poky.conf?h=scarthgap&id=06210079b2e10d6d3fb943afe87864267e329821 if required.

Known Issues and Limitations in Scarthgap (5.0.12)

Upstream

• See https://git.yoctoproject.org/poky/tree/documentation/migration-guides/release-notes-5.0.12.rst?h=scarthgap#n6 CVE patches are applied by the YP community.

• meta-ros2-jazzy hardware-interface fails to build with Scarthgap, See https://github.com/ros/meta-ros/issues/1219

AMD

• See Downloads and Release Notes

• In 5.0.12/2025.2/v25.11 a change was made so that the kernel finds and mounts the root filesystem via a known UUID. The same UUID is used for both the regular *.wic image as well as the *.wic.ufs image. Therefore if a stystem has a filesystem on both a UFS device and some other boot media (SDcard, flash, etc) it is not determinant which image will be mounted and used. The same is true for non-UFS systems in the case where the image might be found on, say, an SDcard and a USB stick.
