I think you may be suffering from the latest LL_TEMAC packet loss problem. (NFS/UDP really does not like packet loss)
Let me guess. You are using a base system from "Base System Builder Wizard"? EDK 9.2i. Default syntheses/P&R options. I have seen a massive packet loss problems on my ML403 and two other boards I have with an FX60. This is probably a hardware problem. Xilinx has acknowledged an LL_TEMAC problem to me but has not provided a fix. I have heard that things are better with EDK/ISE-10.1 but I have not tested it. The vendor of one of my boards (Pico) has fixed the problem on the FX60 by highly constraining the timing of the LL_TEMAC in map/PR. On my ML403 I used similar constraints and it fixed the problem, but only if the device is plugged into a GigE switch. The problem is still there with the same .bit file on a 100-T switch. Are you on a GigE switch? Rob.
