To format with ext4 filesystem you can use ums. Run on target: ums 0 mmc 0 and on host: sudo mkfs.ext4 /dev/sdx1 Signed-off-by: Fabio Berton Signed-off-by: Otavio Salvador --- diff --git a/include/configs/pico-imx6ul.h b/include/configs/pico-imx6ul.h index c775c32690..6a19861da7 100644 --- a/include/configs/pico-imx6ul.h +++ b/include/configs/pico-imx6ul.h @@ -48,7 +48,11 @@ #define DFU_DEFAULT_POLL_TIMEOUT 300 #define CONFIG_DFU_ENV_SETTINGS \ - "dfu_alt_info=boot raw 0x2 0x400 mmcpart 1\0" \ + "dfu_alt_info=uboot raw 0x2 0x400 mmcpart 1;" \ + "boot part 0 1;" \ + "/zImage ext4 0 1;" \ + "/imx6ul-pico-hobbit.dtb ext4 0 1;" \ + "rootfs part 0 2\0" \ #define CONFIG_SYS_MMC_IMG_LOAD_PART 1
