  1. How to use U-Boot on Grinn's liteBoard
  2. --------------------------------------
  3. - Build U-Boot for liteBoard:
  4. $ make mrproper
  5. $ make liteboard_defconfig
  6. $ make
  7. This will generate the SPL image called SPL and the u-boot.img.
  8. - Flash the SPL image into the micro SD card:
  9. sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
  10. - Flash the u-boot.img image into the micro SD card:
  11. sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
  12. - Jumper settings:
  13. S1: 0 1 0 1 1 1
  14. where 0 means bottom position and 1 means top position (from the
  15. switch label numbers reference).
  16. - Insert the micro SD card in the board.
  17. - Connect USB cable between liteBoard and the PC for the power and console.
  18. - U-Boot messages should come up.
