Hi,
Is there a way I can program a EPCQ4ASI8N to work with Cyclone I?
I have to keep some products which still use Cyclone I FPGA with EPCS4SI8N.
Due to EPCS4SI8N discontinuation, the EPCQ4ASI8N might be a possible alternative, as advised in PDN1708.
My problem is that the Cyclone 1 was supported until the Quartus 10.1 version, and the support for the EPCQ4ASI8N begins from Quartus 17.1.
I thought that the solution would be just to take de .pof file, generated by Quartus 10.1, and just program the new device EPCQ4ASI8N with the Quartus 17.1 programer, but I got the following message from Quartus 17.1 programer when I tried to change de device to EPCQ4A:
"Device EPCQ4A selected for replacement is incompatible with target device EPCS4 associated with programming file..."
So I don´t know how to generate the .pof in the old Quartus 10.1 since it does not support EPCQ4A yet.
Is there a better way to do that?

If you still have Quartus 10.1, you can try two things with the Quartus 10.1:
1. Use your existing .pof file and program the EPCQ4A using the 10.1 programmer
2. Generate a new .pof file in the 10.1 programmer for the EPCQ4 flash (without A) and try programming the EPCQ4A device
