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.
