How Can I set up DMA operation with my own PC software application?

Hello Hey Hey,

Can I use the chaining programming files (C:\altera\72\kits\ArriaGX_PCIe\Examples\PCIe_HighPerformanceDesign\Quartus\top_x4.sof) that are installed with the Arria GX dev kit, or do I have to do a complete build of the FPGA build files?

If that is OK, I am seeing some unexpected results. Everytime I try to write and read a BAR, I always read a 0xffff back. Do you have any idea what I might be doing wrong?
