AWR1843BOOST: Issues while implementing tracker alg on device

Tool/software:

I am trying to implement the tracker algorithm with the OOB implementation. I am following Long Distance People Detection Demo for reference. 
Problem: The code hangs at MmwDemo_trackerConfig. 
I am providing all the required configs.

int32_t MmwDemo_trackerConfig(void)
{
    int32_t errCode;

    DebugP_log0("App: Issuing Tracker Static Config IOCTL\n");

    /* DPC pre-start common config */
    // errCode =  DPM_ioctl (dataPathObj->objDetDpmHandle,
   
#ifdef TRACKERPROC_ON_DSP
    errCode = MmwDemo_DPM_ioctl_blocking(gMmwMssMCB.objDetDpmHandle,
                                         DPC_OBJDET_IOCTL__STATIC_TRACKER_CFG,
                                         &(gMmwMssMCB.trackerCfg),
                                         sizeof(DPC_ObjectDetection_TrackerConfig));

    if (errCode < 0)
    {
        System_printf("Error: Unable to send DPC_OBJDET_IOCTL__TRACKER_STATIC_CFG [Error:%d]\n", errCode);
        goto exit;
    }
#else
    errCode = DPM_ioctl(gMmwMssMCB.objDetDpmHandle,
                        DPC_OBJDETRANGEHWA_IOCTL__STATIC_TRACKER_CFG,
                        &(gMmwMssMCB.trackerCfg),
                        sizeof(DPC_ObjectDetection_TrackerConfig));

    if (errCode < 0)
    {
        CLI_write ("Error: Unable to send DPC_OBJDETRANGEHWA_IOCTL__TRACKER_STATIC_CFG [Error:%d]\n", errCode);
    }
#endif

    return errCode;
}
