Regular ContributorWhat is the difference between the working PC and non working PC? Does the PCIe refclk stable?
Occasional ContributorThe issue turned out to be the PCIe slot. I had the adapter cable in a x4 slot. I moved it to a x16 slot and it was ok atleast for Gen2. The PC is PCIe Gen3 but the PC does not load the card under device manager for any Gen3 setting in the IP design example. Also, as you mentioned I had to restart the PC after programming to make the PC scan for the PCIe device. But my colleague is able to scan the device without restarting the PC. Both of us are using Windows 10 just different motherboards. Is there a BIOS setting for this? I couldn't find one but read there is a ACPI setting for hot plug. Do you know? Also, why is Gen3 not working? The other issue is the PCIe test is not passing (Altera_PCIe_Interop_Test from the IP core directory in Quartus folder). The test is able to get all the PCIe details like Hardware ID properly.
