解决方案

There is a chance that TLP requests will be received, typically Vendor Defined Messages and Read Requests, when only stage-1 bitstream is programmed and before stage-2 is loaded.

The core returns unsupported requests (URs) for such requests.

If a Memory Write TLP is received with only stage-1 bitstream programmed, it will set the UR bit in the device status register. 

Note: In some systems it has been observed that ERR_NONFATAL is being sent.
