ML505 NOT RECOGNIZED BY THE PC THROUGH PCI EXPRESS

[ouadrani]

I encounted a problem with my PCI-E design with ML505 in the xapp 859 o
xilinx.
The host PC couldn't detect the ML505 and OS can not recognize the card.
My Ise tools' version is 12.1 .
If the ML505 is powered , the Pc hangs and does not start.
The board use the PC power. When I power up PC the OS was still hang ther

I remember having a problem with that. The solution was configuring
device class and BARs (base address registers).
