How to use U-Boot on MX6Q/DL Udoo boards |
||||||
|
---------------------------------------- |
||||||
|
|
||||||
|
- Build U-Boot for MX6Q/DL Udoo boards: |
||||||
|
|
||||||
|
$ make mrproper |
||||||
|
$ make udoo_defconfig |
||||||
|
$ make |
||||||
|
|
||||||
|
This will generate the SPL image called SPL and the u-boot.img. |
||||||
|
|
||||||
|
- Flash the SPL image into the SD card: |
||||||
|
|
||||||
|
sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync |
||||||
|
|
||||||
|
- Flash the u-boot.img image into the SD card: |
||||||
|
|
||||||
|
sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync |
||||||
|
|
||||||
|
- Insert the SD card in the board, power it up and U-Boot messages should |
||||||
|
come up. |
