I’m working on fast boot of Colibri i.MX7 and the best way how to do it is to use SPL and falcon mode. Is there any documentation about this for Colibri i.MX7 eMMC version? SPL support for i.MX7 was already added to the U-boot so it should be possible.
What I already tried so far was to patch the Toradex U-boot to add SPL support, made SPL image and write it to the mmcblk0boot0 with
dd if=SPL of=/dev/mmcblk0boot0 bs=512 seek=2 , but that didn’t work and nothing happened after boot.
I would appreciate any help with this.
