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