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
