Are you connected to PB using KITL?
In this case check that the BSP_NOSHAREETH environment variable is not
set and that you followed the directions of the article entitled
"Ethernet Debug Sharing Procedures" in PB help.

If your system is working in release mode, without KITL, and the frames
are received only at the ethernet level and not by the TCP/IP stack,
check that the registry settings that link TCP/IP and your network
adapter are correct. Try to build a debug image without KITL and enable
the debug zones related to TCP/IP and network drivers (you should put
the correct entries under HKEY_LOCAL_MACHINE\DebugZones on the target
device).
