Unable to program EPCQ16A on custom cyclone IV board - error during jic flashing.

Hello, I  have created a custom FPGA PCB board with cyclone IV EP4CE6E22C8N FPGA. For flash I have a EPCQ16A. When I try to configure my FPGA in jtag mode MSEL (2:0) = "011", and use the .sof file. ...

Hi Varshasri,

Can you confirm that you are using Cyclone IV GX FPGA Development Kit?

    I am using the cyclone IV EP4CE6E22C8N FPGA chip (not the development board). I have customised my own PCB with this FPGA chip using EPCQ16A for flashing. I found out where the issue is - I have made connection error while connecting my flash to the FPGA. The data0 pin was connected wrongly and hence it was not able to switch to Active Serial mode. Now that I have modified the connections, I am able to flash successfully. Thanks anyway
