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...

You don't need to regenerate the .jic when you change the JTAG frequency.

Fast & slow POR change the speed at which the device comes up. Doesn't come into play until the devices boot from FLASH.

How far from the FPGA is the EPSQ? Have you a source termination resistor on DCLK?

Cheers,

Alex

    The EPCQ is about 2 in. away from the FPGA. And there is no termination resistor on the DCLK. Should there be one? It didn't mention it in the handbook.
