PCIe Driver

Hi,

I'm trying to reuse the older design which uses PCIe x1 in Arria II GX. In new design, I will be using x8 with same part(Arria II GX). We used jungo driver for x1 lane. If I go with x8, is there significant code change? Or is this simple task?

Thanks,

K.

    You might need to change the device ID for the new card and this change will be reflected in your inf file. I guess there should not be any change in the driver source code. The jungo driver does not know if the card is a PCIe x1 or PCIe x8 or PCI card.
