  • kas: Use new commit/branch syntax
  • kas: Update config version to 15
  • Update all meta layers

i.MX Platforms

  • Remove Kernel 5.10 recipe
  • Update to Linux 6.1.97
  • Common usb serial drivers enabled in linux kernel config (FTDI, CH341, CP2102, PL2303, CDC/ACM)
  • The automatic execution of scripts via a USB storage device is disabled by default
  • The attachment of partion label by removable media is disabled by default
  • Kernel has been migrated to use linux-yocto class and configuration fragments
  • Migrate to use meta-ked-bootloader layer with U-Boot 2024.01
  • Enable storage modules- and USB onboard support in Linux kernel config
  • Enable audio drivers in Linux kernel config
  • SWUpdate is no more supported

i.MX8 Platform

  • Upgrade Mesa to v24.0.5 for i.MX8MP hardware to gain OpenGL support for this platform
  • Enable SMARC devicetree for i.MX8MP hardware
  • Enable i.MX8MP USB drivers

i.MX6 Platform

  • Fix an issue with RS485 communication

Breaking Changes

  • Remove Dunfell support and Kernel 5.10

Known Issues

  • The onboard USB hub on the BL i.MX8MM doesn't work in U-Boot.
  • Devices connected to the USB-C connector of the BL i.MX8MP before booting up the board are not detected and need to be reconnected after booting.
  • The touch controller on the DL/DK i.MX8MP devices doesn't work.
  • The SD card on the SMARC i.MX8MP Eval Carrier doesn't work.
  • Kirkstone misses support for hardware-accelerated Wayland on i.MX8MP although GPU support has been backported by upgrading Mesa for this platform.
  • On i.MX8MP there are issues with reading EDID data from some HDMI monitors. This can result in wrong display mode settings.
  • The package python3-pyqt5 fails to build (see https://github.com/meta-qt5/meta-qt5/issues/585). A workaround is to use the kirkstone branch for meta-qt5 with an older patch release of Qt5.15.
