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.
