Second, did you make sure that the COM port was the correct one?
Thirdly, did you select the right board from FPGAconf.exe's menu? It needs to be the Pluto-IIx, of course.
Fourthly, be sure you're using the right .bit file. It needs to be the file named gcvideo-dvi-p2xh-gc-2.3.bit.
Finally, make sure all your wires are still connected and not grounding out or shorting.
Yes, I'm certain that FPGAconf says the programming was successful. It went through all the steps (erasing, programming, verifying) and I watched the LED flash as it did so. The COM port is correct and I know I've selected the right board. I followed the instructions exactly. I'm definitely using the right bit file, and I've tried an older version only to see the same result. My wiring is fine, as it worked before I reprogrammed the FPGA. It's not inside any case and I'm just using the motherboard right now.
The board shows no sign of working at all. It really looks like the FPGA isn't being configured from the PROM when I power it on. I'm suspicious of the version of FPGAconf.exe that I have. You said yours has worked, so could you send me the exact copy you used?
EDIT: I didn't have the right .bit file. Somehow I got a 34 KB file from github with the same name, but that didn't contain the firmware. I got the 147 KB version and it's working now.
