I forgot to connect the nCS pin of EPCQ-A and the nCSO of FPGA (Cyclone Ⅲ) and created a board.
Currently the FPGA nCSO pin is open.
Since it is a BGA package, it is not possible to add wiring.
Doesn't the nCS pin of EPCQ-A work with "Low" fixed?
Is there any good way?
Please help me.
Thank you very much.
