BSP Version History

0006

u-boot: Do not set ethXaddr variables in environment for MAC addresses that are not actually assigned to the module

This affects the TQMa6411L variant, which does not support PRU Ethernet, so only a total of 2 instead of 5 MAC addresses are assigned per module.

0005

Added support for TQMa6411L variant
Changed default sysfw variant to HS-FS

All series variants of the AM64x are HS-FS, the GP variants only exist as prototypes. Change the default sysfw variant for future BSP releases, so our images will work on series modules without changes. For prototype modules with AM64x SR1.0 or SR2.0 GP, the following options are available:

Use the old BSP release kirkstone.TQMa64xxL.BSP.SW.0004
Replace tiboot3.bin with tiboot3-am64x-gp-evm.bin in the boot partition
Change SYSFW_DEFAULT_VARIANT in the machine configuration or local.conf

0004

U-Boot

Added support for booting in USB host mode (from USB mass storage) and device mode (using dfu-util on a connected host)

0003

* Enable SDHC controller quirk to fix SD card access on TQMa64xxL REV.010x SoMs.

0002

BSP

Update to Yocto Kirkstone
Update U-Boot and kernel for hardware revision 0200. The obsolete revision 0100 is not supported anymore.
Update Known Issues

U-Boot

Update to include latest ti-u-boot-2021.01 changes. This fixes a license issue in U-Boot (inclusion of GPL-incompatible code).
Updated for compatiblity with latest meta-ti (commit 2a5a0339d5bd)
Updated build to generate tiboot3.bin for all 3 SYSFW variants (GP, HS-FS, HS-SE). Only boot on GP variants has been actually tested, as no TQMa64xxL with a HS CPU variant exists at this point.
Fix QSPI data corruption in U-Boot when accessing UBIFS volumes

Linux

Fix periodic rescan for SD cards with warning message when no SD card is inserted
Make OSPI working
