1. USB SDP boot
+2. eMMC boot (via DFU)
+
1. USB SDP boot:
---------------
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.
