Inconsistent Performance of Ethernet DM648EVM

Hello all

I am using Hello World Application DM648EVM board from Lyrtech in ALE Bypass mode with NDKv2.0.

The scenario is that TCP/IP packets are exchanged b/w PC's using Ethernet ports. But after 2 hrs or so of communication the board suddenly stops communication, and I am unable to send packets in/out of the board and even ping messages are not received/transmitted. When i stop the code the program counter points to the function local_call_stub or C$L7: or C$L3: and if i re-run the program the progem runs but stil no-communication the communication can only be-resumed if i reload the compiled code's .out file and run.

Please help what going wrong or possible problem?

 

Regards

Mark
