Hi,
Please verify with lspci -n that the Product ID of the FPGA card is 0xebeb. Just a way to make sure that the right thing is running on the card.
Also, please verify that the driver is loaded into the kernel with lsmod. You should see "xillybus" listed (possibly xillybus_core and xillybus_pcie if you have a recent driver). If they're not listed, please insmod the driver manually.
And last, look for Xillybus-related messages in the system log (/var/log/messages or /var/log/syslog, depending on your system's flavor).
Hope this helps,
Eli
