Trouble with programming EPCQ via JTAG interface, cannot find flash loader.

Hello, I am trying to program an EPCQ4A through an FPGA (10CL006ZE144). When I go to create the .jic file, the flash loader for my FPGA is not listed. The closest I can find is 10CL006Z, and when I...

That's the correct device to select when creating your jic file.

What hardware are you using? Given the device you specify I guess it's your own custom hardware.

Can you program the FPGA directly, using the sof, via JTAG? I think this is more likely to be a signal integrity issue.

Cheers,

Alex

    Hi Alex,

    I'm using the USB Blaster II, and I can program the FPGA with a .sof without any issues.

    Thanks,

    After taking another look at my board schematic, I noticed that the 3 MSEL pins are grounded. Could this be the problem? I remember reading somewhere that the FPGA must be set to active serial to program an EPCQ device, but I'm not sure where.
