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 Hugh,

I did as the instructions said and downloaded the file whilst the PC was in the bios and then quit the bios. PC started OK but board was not recognised. I did a reboot and still the same.

Ok, are you sure that the particular design you are downloading "works"? Eg., is there an LED that starts blinking or something? And does this particular design example include a PCIe end-point?

The development kits usually come with a Board-Test-System (BTS) design. Did you confirm your hardware works by running that example in stand-alone mode? The BTS design probably does not have a PCIe core in it.

Cheers,

Dave
