Hi Guys,

Can anyone help in this issue? We still have it:(

Now I am testing the card in a nice Asus P6T7WS Supercomputer motherboard but it does not work in any of the 7 PCIe slots, although it still works well in the old Asus. The software can see it, read and write the internal registers but the data stops in the SGDMA. Maybe some configuration is missing but where? In the software? In the HW/SOPC Builder?

Or what's going on?

Any idea?
