Yes, I think we should be able to adapt dfu_nand to support raw (current) and UBI (which will need a little further handling so you can update per UBI container). In MMC (and there's examples in trats and am335x_evm) we say <name> ext4/fat/part/raw device#/start_blk part#/end_blk. I would imagine, but testing and implementation might show a better way, we do UBI as <name> ubi ubiN volume-name, ie: rootfs ubi ubi0 rootfs user ubi ubi0 user-data and so forth, and augment dfu_nand.c with UBI knowledge, ala dfu_mmc and fat/ext knowledge. -- Tom
