For instructions on installing and using the BMD reference demonstration design refer to xapp1052.pdf Known Issues Item 1: On some Windows based systems it has been observed that if the driver is already loaded when the system boots up, Windows may appear to hang. The problem appears to be a conflict between the driver and some USB drivers. The problem is that the USB drivers stop working and if you have the mouse or keyboard plugged into these USB ports they become unresponsive. This makes it appear the system is hung, but in reality its just the USB port that is not working. Recommendation is to try a different USB port. We found this would solve the issue. This has been seen on an x58 and P55 machine. Item 2: The x8 implementation for the Block Plus core On ML555 has difficulty meeting timing. It may be Necessary to use SmartXplorer to close timing. If using The v1.12 or v1.11 core see Answer Record 33709 for new wrapper file that will help in timing closure. http://www.xilinx.com/support/answers/33709.htm Item 3: The Linux driver is only proven to work on Fedora Core 10. It has not been tested on other Linux versions.
