Seems like SPL (sdc4) at 4th partition and U-Boot proper at first partition which seems an unconventional way to create partition layouts based on the booting stage hierarchy. I did send the changes on top of our changes [1] which indeed follow the conventional partition layout. So feel free to incorporate your series while sending the next version. So from next version, you can drop CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION and write images as, $ sudo dd if=u-boot.itb of=/dev/sda seek=4096 $ sudo dd if=spl/u-boot-spl.bin of=/dev/sda seek=2048 [1] https://patchwork.ozlabs.org/project/uboot/list/?series=168967 Jagan.
