about : UDP by the Ethernet communication

I have a question.

We do a PC and a board using C6745,  communication by the UDP.

  We use NDK 2.20.0426( DSP/ BIOS 5.41.1636).
However, this UDP communication is not possible at all after ARP was published by C6745.
Please let me know, how should it be settled?

    RYUICHI MORITA,

    Are you able to ping the board?

    Can you please elaborate on this more?  Did you modify the ARP table on your PC?  What does the ARP table show on your PC if you run the command "arp -a" in a DOS shell? Are the IP address and MAC address for the 6745 board shown correctly?

    Thank you for your suggestion.

    As for (around one hour), a board using C6745 and the PC comminucation  by UDP communication in 10ms period at a certain time.
    However, ARP is published suddenly by C6745 board, and the PC replies to ARP afterwards.

    The PC publishes a command on C6745 board by UDP, but the C6745 board does not recognize the packet afterwards.

    Please let me know where I investigation.

    Can you ping the board at this point?

    Do you have the NDK client example?  The client example has a UDP server running on it.  It works with the Windows side app "testUdp.exe".  Can you try running the client example and the corresponding "testUdp.exe" program for 1 hour?  Do you experience the same problem with the client example?
