Hi Lokesh,

seems like all boards including include/environment/ti/mmc.h will only search for ${boot_scripts} in the root of the target fs, not in ${boot_prefixes}. Known

It searches in boot partitions of SD cards and this was always the case from a long time.

There is no boot partition in our case. So your open-code approach does not find a /boot/boot.scr on the root partition. It does not evaluate boot_prefixes for the script because it does not use scan_dev_for_boot & friends.

bug? Used to work fine with your downstream U-Boot some years ago. Just updated

Any chance you re collect which U-Boot version?

Oh, I found the reason: I fixed up that BSP with an own environment back then, to emulate what proper distro boot would have found.

an SD card, only replacing the bootloader artifacts, and that card now no longer boots.

We are planning to move to distro boot completely. It should clean all the env variables.

That will likely help. Anything that complicates this because of backward compatibility? Otherwise, it should just be about removing own defines. I just cleaned up our k3-based board this way, simply dropping all the stuff that piled up during early development.
