Code:

Hey @zener, did you ever get this working?  I was looking at this board specifically to use with an Xtra, so hoping someone has blazed the trail Smile

Sorry about the late reply.

No I could not get it working. The recent PCIe driver will load, the low level test application will not crash:

But when I run the test application it will crash:

In the kernel log I observe:
