AWR1642: how to reconfiguration the register "FrameCfg" in the dss side

hi 

i have some problem when i used the mmwave_demo code. I wanna reconfiguration the register "FrameCfg"  every frame in the dss side.

i trying to insert the code segment into the function "MmwDemo_dssFrameStartIntHandler"("C:\ti\mmwave_sdk_01_00_00_05\packages\ti\demo\xwr16xx\mmw\dss\dss_main.c").but it  got error.

would you please tell me what the error means and how to deal with it?

if this method is wrong , have some advice for the other ways?

code segment:

static void MmwDemo_dssFrameStartIntHandler(uintptr_t arg)
{
    int32_t errCode = 0;

    if(gMmwDssMCB.state == MmwDemo_DSS_STATE_STOPPED)
    {
        gMmwDssMCB.stats.frameIntSkipCounter++;
        return;
    }

    if(gMmwDssMCB.state == MmwDemo_DSS_STATE_STOP_PENDING)
    {
        /* stop the clock as the DSP will be stopped at the end of this active frame */
        Clock_stop(gMmwDssMCB.frameClkHandle);
    }

    if (errCode != RL_RET_CODE_OK)
    {
        /* Error: Setting the chirp configuration failed */
        System_printf ("Error: frame configuration error [Error code %d]\n", errCode);
    }

    /* Check if previous chirp processing has completed */
    DebugP_assert(gMmwDssMCB.dataPathObj.interFrameProcToken == 0);

    gMmwDssMCB.dataPathObj.interFrameProcToken++;

    /* Increment interrupt counter for debugging purpose */
    gMmwDssMCB.stats.frameStartIntCounter++;

    /* reconfiguration the frame */
    errCode = rlSensorStop (RL_DEVICE_MAP_INTERNAL_BSS);

    if (errCode != RL_RET_CODE_OK)
    {
        System_printf ("Debug : sensor stop error\n");
    }

    gframeCfg.chirpStartIdx        = 0;
    gframeCfg.chirpEndIdx          = 511;
    gframeCfg.numLoops             = 1;
    gframeCfg.numFrames            = 0;
    gframeCfg.framePeriodicity     = 100 * 1000000 / 5;
    gframeCfg.triggerSelect        = 1; //Software API based triggering
    gframeCfg.frameTriggerDelay    = 0 * 1000000 / 5;

    errCode = rlSetFrameConfig(RL_DEVICE_MAP_INTERNAL_BSS, &gframeCfg);
    if (errCode != RL_RET_CODE_OK)
    {
        System_printf ("Debug : frame configuration error\n");
    }

    errCode = rlSensorStart (RL_DEVICE_MAP_INTERNAL_BSS);
    if (errCode != RL_RET_CODE_OK)
    {
        System_printf ("Debug : sensor start error\n");
    }


    /* Post event to notify frame start interrupt */
    Event_post(gMmwDssMCB.eventHandle, MMWDEMO_FRAMESTART_EVT);
}

the error shows as below:
