How to use U-Boot on Freescale MX6UL 14x14 EVK
- Build U-Boot for MX6UL 14x14 EVK:
$ make mrproper
$ make mx6ul_14x14_evk_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:
SW601: 0 0 1 0
Sw602: 1 0
where 0 means bottom position and 1 means top position (from the
switch label numbers reference).
- Connect the USB cable between the EVK and the PC for the console.
(The USB console connector is the one close the push buttons)
- Insert the micro SD card in the board, power it up and U-Boot messages should
come up.
