How to use U-Boot on Grinn's chiliBoard |
||||
-------------------------------------- |
||||
|
||||
- Build U-Boot for chiliBoard: |
||||
|
||||
$ make mrproper |
||||
$ make chiliboard_defconfig |
||||
$ make |
||||
|
||||
This will generate the SPL image called MLO and the u-boot.img. |
||||
|
||||
- Flash the SPL image into the micro SD card: |
||||
|
||||
sudo dd if=MLO of=/dev/mmcblk0 bs=128k; sync |
||||
|
||||
- Flash the u-boot.img image into the micro SD card: |
||||
|
||||
sudo dd if=u-boot.img of=/dev/mmcblk0 bs=128k seek=3; sync |
||||
|
||||
- Jumper settings: |
||||
|
||||
S2: 1 1 1 0 1 0 |
||||
|
||||
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 chiliBoard and the PC for the power and console. |
||||
|
||||
- U-Boot messages should come up. |
