Change dfu_alt_info variable to use the following altsetting:
uboot: To flash raw U-Boot /zImage: boot: To copy kernel image /imx6ul-pico-hobbit.dtb: To copy dtb file rootfs: To copy rootfs
List the currently attached DFU capable USB devices running: sudo dfu-util -l
Flash U-Boot: sudo dfu-util -D u-boot.imx -a uboot
Copy boot files: sudo dfu-util -D zImage -a /zImage sudo dfu-util -D imx6ul-pico-hobbit.dtb -a /imx6ul-pico-hobbit.dtb
Flash rootfs: sudo dfu-util -D rootfs.ext4 -a rootfs
To copy boot files you need to have a formated mmc 0:1 partition. To format with ext4 filesystem you can use ums.
Run on target: ums 0 mmc 0
and on host: sudo mkfs.ext4 /dev/sdx1
