Failed to Enumerate Stratix IV GX FPGA Development PCIe Board on PCIe 3.0 Bus

Ritesh,

This is where I would start.

http://www.altera.com/products/devkits/altera/kit-siv-gx.html

That URL contains everything but still says it supports PCIe Gen2 X8 ... I didn't see any mention of Gen3 speed.

Were you able to determine where the .sof came from ?

Best Regards, Bob.
