sendto failed in udp data streaming

GOPISH R K

Hi,

    I'm trying to send data from one OMAPL 138 evm to another OMAPL 138 evm through udp protocol.

In my application receiver side is working fine,but I'm getting fdError() as 55 in the transmitter side after sendto() function.

While looking into 'serrno.h' it is found to be error code corresponding to 'ENOBUFS' but I don't know in detail why it happens even though there is enough heap space 

anyone do know what might be the real cause.

any suggestion will be appreciated

-Thanks

    Hi Gopish,

    What is the OS version? Whether the application code is working b/w two systems or two other boards? whether the code is proven one?

    Whether the ethernet device is working fine in each board?

    -Thanks

    Hi Balaji,

                    Thanks for your reply,here is the answers for your queries,

    The bios version using is bios_5_41_02_14 (I'm using only DSP core in OMAPL 138 EVM)

    Balaji Nagarajan said:

    The application is an audio encoding decoding system with real time capture and play, in which one EVM is used as transmitter which transmits the encoded data and another EVM as receiver which receives the encoded data and decodes it and they are connected through Ethernet cable.  For capturing and playing audio, I'm using McASP driver in BIOS PSP.

    I tested the encoder and decoder both running on one evm without ethernet communication and it worked fine.

    And I think ethernet device on both the boards are working fine,because both are responding to ping request

    I am using following tools:

    -CCS v4.1

    -XDS100v2 emulator

    -NSP 1.00.00.09

    -NDK 2.20.00.19

    -pspdrivers_01_30_01

    -edma3_lld_01_11_03_01

    -Thanks
