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 bug? Used to work fine with your downstream U-Boot some years ago. Just updated an SD card, only replacing the bootloader artifacts, and that card now no longer boots.
