Linux/PROCESSOR-SDK-AM335X: U-Boot in EXT2/3/4 partition

Part Number: PROCESSOR-SDK-AM335X

Tool/software: Linux

Good Afternoon,

for my current project requirements we need to implement a single partition(Ext2/3/4) with both U-boot and ROOTFS.

I read that u-boot should only execute from FAT format partition. Is there a way to make it work under Ext partition as well?

Regards and many thanks in advance,

Pedro

    I confirm Biser's answer. This has not been tested.
