I sent a v2. The order is: Use the default environment variables: => env default -f -a => saveenv To ensure we are using the proper eMMC partition for boot, please run: => mmc partconf 0 0 0 0 Next, run the DFU agent so we can flash the new images using dfu-util tool: => dfu 0 mmc 0 Flash SPL and u-boot-dtb.img into the eMMC running the following commands on a PC: $ sudo dfu-util -D SPL -a spl $ sudo dfu-util -D u-boot-dtb.img -a u-boot The environment setup but be run using the current U-Boot as it has the dfu_alt_info which needs to be used. Please try this sequence and see if it works for you. -- Otavio Salvador O.S.
