Frequent ContributorHi WShih8,
May I know how do you read your original pof checksum? (Is it from Quartus Programmer?)
And how do you readback checksum after power cycle?
FYI, Quartus programmer checksum different than general checksum calculations of the .pof.
For more details, please refer to following link:
