Arria 10 PCIe Avalon-MM DMA Reference Design: Read/Write Timeout

Still struggling to understand what's going on here. Same error on both Windows 10 and CentOS. I have a dual boot setup on the same PC where the card is installed. Extension cable is not used here. I've also attempted to change the memory maps for RD/WR master and the device ID, still the same result. I never have an issue with seeing the device nor is the BARs disabled, I just can't read/write to the on chip RAM. I'm at a loss here as to what the issue would be.
