This question is related to the below one
I got below error code in the CSE_ECR right after writing master key
I found the reason of the error in the "AN4234_Using the Cryptographic Service Engine(CSE)MPC564XBC.pdf" document, but I still didn't understant the real reason.
But after checking the RCHW in the below question, I got to know the my RCHW has no problem
Then, is there any other reason that generating 0x0C in ECR register?
