We have one board that has multiple migration devices. Up until now we have been using EP4CE55 with an eeprom (mode=2) and EP4CE115 with software download (mode=0).
We recently recieved an order for the board with EP4CE75. Mode 0 works on all of the boards, however the eeproms aren't working.
EP4CE55 -- EPCQ16 <-- works OK!!
EP4CE75 -- EPCQ32 will program with Quartus programmer but will not load on power up until I disable the ID check while converting the programming file. (This ID IS 16).
EP4CE75 -- EPCQ32A will not program. "Device 1 has wrong silicon ID" (This ID IS 16).
I'm using Quartus 15 thru 19.
We would like to be able to program the parts with the A in the future.
Thank you for contacting Intel community.
Please be noted that EPCQ-A device only support Quarus 17.1 and above.
Please refer to below link for further information:
This is Quartus 19 with a "A" device and a working board.
Per my original question. "I'm using Quartus 15 thru 19".
