I'm trying to create a jic file for the CycloneV SOC dev kit. The 'Convert Programming File' doesn't have the correct device available.

Fixed. The Flash Loader gives 5csxfc6d6. This is good enough for the Cyclone V SOC dev kit which has a 5csxfc6d6f31c6n. My issue was with the inverted logic of the switches used to set the MSEL settings. I'm currently using a JIC file to program the EPCQ256 in ASx4 mode. Runs great.
