How to use U-Boot on MX6Q/DL Udoo boards
----------------------------------------
- Build U-Boot for MX6Q/DL Udoo boards:
$ make mrproper
$ make udoo_defconfig
$ make
This will generate the SPL image called SPL and the u-boot.img.
- Flash the SPL image into the SD card:
sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
- Flash the u-boot.img image into the SD card:
sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
- Insert the SD card in the board, power it up and U-Boot messages should
come up.
