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
