Dear sir,
I have signed uboot & using kernel 4.9.11 for secure boot running on i.MX6-based board.Reference https://community.nxp.com/docs/DOC-330622,I want to encrypt uboot ,but need to burn OTPMK by nxp factory. So, I change the cst file (ZMK from SNVS).but i do not know how to encrypt / decrypt by ZMK, can you provide assistance?
Best Regards,
Hello,
The OTPMK in i.MX devices, which are provided to the customers, is already burned.
The ZMK is not used for encrypted boot.
Regards,
Yuri.
