Hi folks,
Just curious if you ever faced any issues with HABv4 based secure boot on iMX7 SoC-based boards + NAND + mainline U-Boot (although it works perfectly when booting from eMMC).
I'm currently playing with it on Colibri iMX7 NAND version, following all steps from [1], (colibri_imx7_defconfig, where CONFIG_SECURE_BOOT=y and CONFIG_FSL_CAAM=y, without these two options enabled it's booting ok) and facing the same issue as explained in one of NXP forum threads [2]. Taking into account that default BootROM doesn't provide any output at all to the serial console it is like looking for a needle in a haystack.
Do you have any ideas about possible pitfalls/what could be missing in this puzzle? Or at least some hints where to look into?
Thanks in advance!
