How to use U-Boot on Engicam i.CoreM6 DualLite/Solo and Quad/Dual Starter Kit:
-----------------------------------------------------------------------------
- Configure U-Boot for Engicam i.CoreM6 QDL:
$ make mrproper
$ make imx6qdl_icore_mmc_defconfig
- Build for i.CoreM6 DualLite/Solo
$ make
- Build for i.CoreM6 Quad/Dual
$ make DEVICE_TREE=imx6q-icore
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
- Flash the u-boot-dtb.img image into the micro SD card:
sudo dd if=u-boot-dtb.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
