Description
Due to a known issue with the Programmer in Quartus® Prime software version 15.1 and earlier, you may fail to program the non-volatile key when Active Serial (AS) configuration mode is being used in Arria® V, Cyclone® V and Stratix® V devices.
Resolution
This issue has been fixed in the Quartus Prime software version 15.1.1 and later. The fix can be used to generate a JAM, JBC or SVF file to program the non-volatile key as well.
For stand-alone Programmer users, only Quartus Prime Programmer version 16.0 and above may be used.
