Hsow to use U-Boot on Engicam i.CoreM6 (RQS) Solo/DualLite/Quad/Dual Starter Kit:

This will generate the SPL image called SPL and the u-boot-dtb.img.
- Flash the SPL image into the micro SD card:
sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync

sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
- Jumper settings:

(J28 is the Linux Serial console connector)
- Insert the micro SD card in the board, power it up and U-Boot messages should
