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.
