Hello,
I'm currently working on the i.Mx6.
I'm looking to modify the "master key".
It seems that the OTPMK key has already been fused on my board. By reading bit 0 of the SNVS_HP register, the OTPMK_ZERO bit is at 0.
However, the SSM_ST bit content is equal to 1011 (0xb), which means that my device is in Non-secure mode.
In this specific case, I can no longer modify the OTPMK key, is this correct?
Can I use the ZMK key instead of the OTPMK ?
What is the correct procedure to do that ?
Do I have to put the device in secure mode for the ZMK key to be taken into account?
Best Regards
