RTOS/TDA2PXEVM: Using A15 instead of IPU

Part Number: TDA2PXEVM

Tool/software: TI-RTOS

Hello,

I wrote new algo link and it is working well in IPU0_1.

But, when I change the processor for new algo link to A15, a link creation was failed like below:

The only difference is a processor configureation.

I modified a chains_issIspSimcop_Display.txt (Alg_newalgolink (IPU0_1) to Alg_newalgolink (A15)),

and regenerated usecase.

Could you give me some advice why this situation happend?

    Hi Jeon,

    In addition to this, you also require to add this algorithm for A15. Please include this algo in A15, register it for A15, include alg id for A15 etc..
    Without this, since algo is not registered for A15, it will fail.

    Hi Brijesh,

    At first, I modified ~/vision_sdk/apps/src/common/app_init/app_init_a15.c file.

    I put some code like below:
    #ifdef ALG_NewAlgo
    Int32 AlgorithmLink_NewAlgo_initPlugin(void);
    #endif

    and.. call AlgorithmLink_NewAlgo_initPlugin(); functions at App_init()
    #ifdef ALG_NewAlgo
    AlgorithmLink_NewAlgo_initPlugin();
    #endif

    Next, I modifed ~/vision_sdk/apps/src/rtos/usecases/iss_capture_isp_simcop_display/chains_issIspSimcop_Display.c
    I put some code in chains_issIspSimcop_Display_SetNewAlgoAlgPrms()
    if (chainsCfg->algProcId == SYSTEM_PROC_A15_0)
    {
    pPrm->baseClassCreate.algId = ALGORITHM_LINK_A15_ALG_NEWALGO;
    }

    and add some code in chains_issIspSimcop_Display_SetAppPrms()
    pUcObj->IPCIn_A15_0_IPU1_0_0LinkID =
    SYSTEM_MAKE_LINK_ID(pObj->chainsCfg->algProcId, pUcObj->IPCIn_A15_0_IPU1_0_0LinkID);
    pUcObj->Alg_NewAlgoLinkID =
    SYSTEM_MAKE_LINK_ID(pObj->chainsCfg->algProcId, pUcObj->Alg_NewAlgoLinkID );
    pUcObj->IPCOut_A15_0_IPU1_0_0LinkID =
    SYSTEM_MAKE_LINK_ID(pObj->chainsCfg->algProcId, pUcObj->IPCOut_A15_0_IPU1_0_0LinkID );


    What should I do next?

    Thank you.

    Regards,
    Jeon
