XDMA allow multiple FPGA baords to be seen on a motherboard.

I have 1 motherboard running Ubuntu. 18.04.2

I am using latest XDMA drivers from GIThub.

I can only seen one FPGA even though I have 2 on seperate PCI slots.

One is visible and the driver works as expeceted. I just can get them both to show up.

Each one on their own will load if alone and I can see and program them each. Just gets messed up when 2 are present.

I am using an X570-P motherboard.

 

Any adive appreciated.
