| How to use U-Boot on Engicam i.CoreM6 DualLite/Solo and Quad/Dual Starter Kit: |
| ----------------------------------------------------------------------------- |
| |
| - Build U-Boot for Engicam i.CoreM6 QDL: |
| |
| $ make mrproper |
| $ make icorem6qdl_mmc_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: |
| |
| MMC Boot: JM3 Closed |
| |
| - Connect the Serial cable between the Starter Kit and the PC for the console. |
| (J28 is the Linux Serial console connector) |
| |
| - Insert the micro SD card in the board, power it up and U-Boot messages should |
| come up. |
| |
| - Note: For loading Linux on Quad/Dual modules set the dtb as |
| icorem6qdl> setenv fdt_file imx6q-icore.dtb |
