I have a BF518F evaluation board and be able to run project: C:\Program Files (x86)\Analog Devices\VisualDSP 5.0\Blackfin\Examples\OTPProgrammer to enter secure mode.


I tried to program my BF512F device with same customer ID read out from BF518F on the evaluation board from address 0x10-0x12 of OTP area.

However, running project OTPProgrammer on my device BF512F still failed to pass authantication. I am using exact same key pair as the eval board, why it still fail firmware authantication? Is there anything else ROM firmware need to check for authentication? Thanks
