cl-som-imx6/MX6D boot issue (pre-compiled image only)

Symptom

IMX6D configuration did not have a correct boot script handling. As a result the boot script tries to load a device tree with the imx6-wrong-sbc-imx6-hdmi.dtb name. The file does not exist and the boot script can't get the device booted.

Fix

• Stop in U-Boot and create a fake cpu_type environment variable. Make the device boot up with. Issue:

setenv cpu_type MX6Q; boot

• Let the device boot up
• Mount the boot partition.

$: umount /dev/mmcblk2p1 ; mkdir /tmp/boot ; mount /dev/mmcblk2p1 /tmp/boot

• Create a copy of the imx6q-sbc-imx6-hdmi.dtb file with the name imx6-wrong-sbc-imx6-hdmi.dtb. Issue:

$: cd /tmp/boot; cp imx6q-sbc-imx6-hdmi.dtb imx6-wrong-sbc-imx6-hdmi.dtb; cd -

• Reboot the machine. Make sure that the device boots up correctly.
