Cyclone IV GX FPGA Development board not recognised by PC when in PCIe slot

Just received a Cyclone IV GX FPGA Development kit and downloaded the demo c4gx_PCIe_gen1_x1.sof to it but when the PC boots up id does not recognise the board. I am unable to install a driver for it...

Hi Dave,

I downloaded a BTS test file into the development board and tried the BTS software in stand alone mode. That worked OK.

I then downloaded the demo sof file into the board in stand alone mode and that works, well I assume it does as the board behaves differently and a user LED blinks. The same happens when I put the board into the PC and program it in situ. The PC I am using is Windows 7 and not XP but I would assume that it would see the board regardless of operating system.

The sof file I am using is the one from the demo directory in the kit (c4gx_PCIe_gen1_x1.sof) which I assume works. I just need a starting point that works.

Cheers

Hugh
