Changes from 6.3.2 to 7.0#

Integrated Components#

  • Yocto 5.0 LTS "Scarthgap"
  • Linux 6.12 LTS with KED backports and patches
  • U-Boot 2024.01 with KED backports and patches (KED Bootloader 1.2.0-dev)

Core/Distro Changes (all HW Platforms)#

  • Upgrade from Yocto v4.0 "Kirkstone" to Yocto v5.0 "Scarthgap"
  • Update kas to v5.2
  • Use kernel 6.12-ktn for all platforms
  • Integrate the meta-ked-bootloader layer into the meta-ked-bsp repo
  • Remove Qt framework from reference BSP and images
  • Remove SWUpdate framework from reference BSP and images
  • Remove deprecated backports for several recipes/packages
  • Remove NFS server from image-ked-minimal
  • Switch to systemd as init manager
  • Switch to Debian package format
  • Remove userfs partition from fstab
  • CI: Implement automated layer updates
  • CI: Rework release artifacts packaging
  • CI: Create self-contained BSP release package
  • Testing: Add automated tests on real hardware via Labgrid
  • Simplify handling of linux-ktn configuration fragments

i.MX Platforms#

  • Various small fixes and improvements for the hardware support of Kontron boards and modules.

STM32MP1 Platform#

  • Add initial support for the platform

Breaking Changes#

  • Major release, expect breaking changes

Known Issues#

  • All platforms: USB OTG interface host mode is not supported in U-Boot.
  • i.MX6UL and STM32MP1: USB OTG interface automatic role switching not supported in Linux.
  • STM32MP1: Display not supported.
  • STM32MP1: QSPI flash memory drivers cannot probe NOR/NAND devices as a built-in kernel drivers. As a workaround, they are built as modules. therefore, booting from NAND is not supported.
  • i.MX8MM: The watchdog timer does not start automatically in U-Boot.
  • i.MX8MP: There are issues with reading EDID data from some HDMI monitors. This can result in wrong display mode settings.
  • i.MX8MP: The EERAM on the BL board does not work reliably.
