Verify USM pass

Verify CFM Fail

Message :

209012 Operation failed

--------------------

to check the behavior i bought a brand new DK-DEV-5M570ZN Development Kit

connection all fine.

Erase performed success

Blank Check success

now examine the erased blank Chip - save the File and now verify of the examined erased/blank chip

........ Failed

So this is not a Hardware or Security Bit Problem -- seem to be a Bug in Quartus
