Building U-Boot for Wandboard
-----------------------------
To build U-Boot for the Wandboard:
$ make wandboard_config
$ make
Flashing U-Boot into the SD card
--------------------------------
- After the 'make' command completes, the generated 'SPL' binary must be
flashed into the SD card;
$ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
(Note - the SD card node may vary, so adjust this as needed).
- Flash the u-boot.img image into the SD card:
sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
- Insert the SD card into the slot located in the bottom of the board (same side
as the mx6 processor)
- Connect the serial cable to the host PC
- Power up the board and U-Boot messages will appear in the serial console.
