Known Issues#

  • The onboard USB hub on the BL i.MX8MM doesn't work in U-Boot.
  • Kirkstone misses support for hardware-accelerated Wayland on i.MX8MP although GPU support has been backported by upgrading Mesa for this platform.
  • 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.
  • USB host mode for USB OTG port on BL boards in u-boot is not supported.

Head of support/6.x branch#

Based on version: 6.3.3

Core/Distro Changes (all HW Platforms)#

i.MX Platforms#

i.MX8MM Platform#

i.MX8MP Platform#

i.MX93 Platform#

  • u-boot bootloader
  • Fix of USB Port assignment The assignment of the USB ports is wrong and needs to be swapped. The OTG (USB-C) port is on the first port and the host port with the onboard hub is on the second port.
  • Enable driver for USB hubs (CONFIG_USB_ONBOARD_HUB)

i.MX6UL/ULL Platform#

  • u-boot bootloader: i2c driver enabled in build configuration

Breaking Changes#

  1. Basic support doesn't include all features of the board. Especially advanced peripherals like display, graphics, hardware acceleration units, camera interfaces, etc. might not be supported or tested yet. ↩↩

  2. With additional KED backports and patches ↩↩↩↩↩↩↩↩
