  1 +How to use U-Boot on MX6Q/DL Udoo boards
  2 +----------------------------------------
  3 +
  4 +- Build U-Boot for MX6Q/DL Udoo boards:
  5 +
  6 +$ make mrproper
  7 +$ make udoo_defconfig
  8 +$ make
  9 +
  10 +This will generate the SPL image called SPL and the u-boot.img.
  11 +
  12 +- Flash the SPL image into the SD card:
  13 +
  14 +sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
  15 +
  16 +- Flash the u-boot.img image into the SD card:
  17 +
  18 +sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
  19 +
  20 +- Insert the SD card in the board, power it up and U-Boot messages should
  21 +come up.
