Right, I did find a way to reproduce it locally. It's indeed the change in fdtdec_setup() that break this platform. Specifically board_fdt_blob_setup() in board/xilinx/common/board.c will return -ENXIO if the DTB is not found. Apparently that's ok for this platform so returning 0 there fixes the boot. It's also another reason why we need the errno instead of just checking the pointer .... Want me to send a v4 of the OF_HOSTFILE version? Cheers /Ilias
