6678DSP_SRIO

Hi,

I am working on 6678 SRIO_LoopbackDioISRexampleproject. I created my own custom project as a new empty RTSC project and added a new RTSC Configuration file. I was going through SRIO_LoopbackDioISRexampleproject and it generates  linker file(.cmd file) in the Debug folder of  SRIO_LoopbackDioISRexampleproject. How that .cmd file is generated, as that cmd file has references to "loopbackDioIsr_pe66.oe66". Is it through .MAK file with makefile?. Please clarify me.

Thank You,

VSagar

    HI,

    Both(loopbackDioIsr.cmd and loopbackDioIsr_pe66.oe66) are indepentent. Please take a look at below wiki link.

    http://processors.wiki.ti.com/index.php/Files_in_CCS_Projects#Linker_command_files

    Yes, the .MAK file is a makefile.

    Thanks,

    Hi Ganapathi,

    Thanks for the reply. The "ti.drv.srio.ae66" file which was refenced in .cmd file generated from .cfg file was in C:\ti\pdk_C6678_1_1_2_6\packages\ti\drv\srio\lib. If I want to modify the ti.drv.srio.ae66 how I can do?  Is there any reference project for four dsp's connected through SRIO switch? LoopbackDIOIsr and TputBenchmarking are not working for DSP's on the same board.

    Thank You,

    VSagar

    Hi,

    MCSDK SRIO Throughput test code support SRIO switch. Better to try this SRIO example for your testing.

    MCSDK Path: C:\ti\pdk_C6678_1_1_2_6\packages\ti\drv\exampleProjects\SRIO_TputBenchmarkingTestProject

    Refer section "5.4 Single EVM looped back externally using an external SRIO switch" and "9.3 Setting up C-S-C connection mode (core to core, with a SRIO switch)" on SRIO_Benchmarking_Example_Code_Guide document.

    Doc Path: \ti\pdk_C6678_1_1_2_6\packages\ti\drv\srio\test\tput_benchmarking\docs\SRIO_Benchmarking_Example_Code_Guide.

    Please take a look at below thread for SRIO lib rebuild.

    Hi Ganapathi,

    Thanks for the reply. I am trying to communicate between two DSP's that are connected through SRIO switch. I have created my own custom project by taking LoopbackDioISRexample project as reference. I am able to do the Initializations(enable srio, systeminit, sriodeviceinit) and port is OK. I am struck at Srio_start function. I went step by step and found out that Qmssprogramaccumulator is not happening. I compared with Tputbenchmarking example and it is poll based and also Appmanagedcfg. LoopbackDioISRexample is Drvmanagedcfg. Why Qmssaccumulator is not configuring? Can you please help

    Thank You,

    The result I am getting from Qmssprogramaccumulator is 6 which is defined as QMSS_ACC_INVALID_QUEUE_NUMBER. Where I am going wrong?

    Thanks

    Hi,

    I went inside programAccumulator and it is writing channel and command in word0  and that is 81 for Acc_cmd for channel enable and FF for cor number (81FF writing in cmd.word0). But in register(reg) all the other three words are same as cmd.word 1 to3 but word0 only it is showing 6000FF. I am not getting how 81FF is becoming 6000ff in register(reg)?

    Thanks
