DATA TRANSFER USING SRIO IN 6670 EVM BOARDS USING loopbackDioIsr example project.

NITHIN BOJJA

Hi,

     I want to do simple data transmit and receive using srio interface between two evm 6670 boards using breakout card. I have bought two 6670 evms and breakout card from TI. I have run the loopbackDioIsr code with no changes and data transfer was successful (internal loopback). Then I wanted to do data transfer between two evm boards with necessary changes but i was unable to do data transfer. Also I could not get portok. I have run the SRIO_TputBenchmarkingTestProject using the same setup and i have got latency and throughput results. But I am finding it difficult to understand the code especially how data transfer is happening. I want to do simple data transfer and I feel loopbackDioIsr is apt for my requirement. Can you send me the loopbackDioIsr code with necessary changes with the requirement that I have to do data transfer between two boards. I have made the necessary changes following the forum http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/p/170264/675812.aspx#675812 but could not be successful, I need this work urgent because I want to test my algorithm on the evm board and then on my custom board.  

                                              Please help me out.            

                                                                                              Thanks and Regards,

                                                                                                          Nithin B

    Hi Nithin,

    Simple board to board communication SRIO example is available in MCSDK package. Please take a look at this example.

    MCSDK Path: \ti\pdk_C6678_1_1_2_6\packages\ti\transport\ipc\examples\srioIpcChipToChipExample\producer

    \ti\pdk_C6678_1_1_2_6\packages\ti\transport\ipc\examples\srioIpcChipToChipExample\consumer

    Refer \ti\pdk_C6678_1_1_2_6\packages\ti\transport\ipc\examples\srioIpcChipToChipExample\Readme.txt file for more information.

    Thanks,
