Changelog

BSP version history

REV.0124

BSP

  • Update to Yocto Kirkstone
  • Update documentation
    • Add issues
    • Add infos for boot sources and update
  • Allow configuration of boot VFAT size. This enables smaller sizes if the kernel image will be installed into /boot which is the default now.
  • Do not install kernel and dtb into boot VFAT image. The images are already found and used from /boot
  • Add ubi to MACHINE_FEATURES since we have an optionally assembled SPI-NOR, ubi should be added to have the ability to install MTD utils in rootfs based on MACHINE_FEATURES
  • Installation of MLO for SPI NOR Flash in Yocto recipe
  • SPI NOR boot support

U-Boot

  • Fixed incorrect MAC addresses in environment
  • SPDX license header for TQMa335x[L] sources and DT
  • Backport fixes for environment for multiple environment location support
  • Cleanup update scripts and variables

Linux

  • Change compression to speed up booting
  • Disable debug options to speed up booting
  • Rewrite recipe to support config fragments
  • Port some config fragments from TQMa6
  • Use same e-MMC pad configs in DT as in U-Boot

REV.0123

U-Boot

  • Fixed incorrect MAC addresses in environment

REV.0122
