We can see U-Boot boot from USB SDP on minicom
2. eMMC boot via DFU:

Once booted from USB SDP, program the eMMC as below(make sure to connect USB OTG)
- Change eMMC partition config
=> mmc partconf 2 1 0 0
- Partition eMMC on host
=> ums 0 mmc 2
Host will able to detect the eMMC disk as UMS, partition the same.
- Program SPL
=> setenv dfu_alt_info $dfu_alt_info_spl
=> dfu 0 mmc 2
At Host
# dfu-util -D SPL -a spl
- Program u-boot-dtb.img
=> setenv dfu_alt_info $dfu_alt_info_uboot
=> dfu 0 mmc 2
At Host
# dfu-util -D u-boot-dtb.img -a u-boot
Poweroff and Poweron the board and see U-Boot booting from eMMC.
