TDA4VM: SPI: trying to access mcu domain SPI interrupt from main domain

Hi all,

Am trying to access mcu_mcspi0 from main domain using interrupt method  am trying to access the  from interrupt router. Can any one suggest me how to configure the router in the application.

Am using TI SPI example loopback application in  baremetal. Its works fine in polling method. When i  was trying with interrupt method; loopback is failing

 I have changed the rmIrqReq.dst_host_irq  value to different locations like from 255 to 412, but still interrupt is not configure.

Am adding the code which is present in McspiApp_Startup.c with the changed i made for configuring the interrupt

if (cfgPtr->hwUnitCfg[idx].enabledmaMode == FALSE)
{
rmIrqReq.valid_params = TISCI_MSG_VALUE_RM_DST_ID_VALID;
rmIrqReq.valid_params |= TISCI_MSG_VALUE_RM_DST_HOST_IRQ_VALID;
rmIrqReq.src_id = TISCI_DEV_MCU_MCSPI0;
rmIrqReq.global_event = 0U;
rmIrqReq.src_index = 0U;
rmIrqReq.dst_id = TISCI_DEV_R5FSS0_CORE1;//tried to give the interuput router address//TISCI_DEV_R5FSS0_INTROUTER0//
rmIrqReq.dst_host_irq = //258;//APP_SPI_MCU_0_INT;//Trying to add differnt interupt lcation here
rmIrqReq.ia_id = 0U;
rmIrqReq.vint = 0U;
rmIrqReq.vint_status_bit_index = 0U;
rmIrqReq.secondary_host = TISCI_MSG_VALUE_RM_UNUSED_SECONDARY_HOST;
retVal = Sciclient_rmIrqSet(
&rmIrqReq, &rmIrqResp, APP_SCICLIENT_TIMEOUT);

if(CSL_PASS != retVal)
{
AppUtils_Printf(APP_UTILS_PRINT_MSG_NORMAL,
"Error in SciClient Interrupt Params Configuration!!!\n");
}
Osal_RegisterInterrupt_initParams(&intrPrms);
#if (STD_ON == SPI_UNIT_MCU_MCSPI0_ACTIVE)
#if (SPI_ISR_TYPE == SPI_ISR_CAT1 || SPI_ISR_TYPE == SPI_ISR_VOID)
intrPrms.corepacConfig.arg = (uintptr_t)Spi_IrqUnitMcuMcspi0TxRx;
#endif
#endif
intrPrms.corepacConfig.isrRoutine = &SpiApp_SpiXIsr;
intrPrms.corepacConfig.priority = 1U;
intrPrms.corepacConfig.corepacEventNum = 0U; /* NOT USED ? */
intrPrms.corepacConfig.intVecNum =//258//APP_SPI_MCU_0_INT;

osalRetVal = Osal_RegisterInterrupt(&intrPrms, &hwiHandle);

my doubt is

1.how I can access mcu_mcspi0 from main domain using the interrupt method

2.Am trying to use interrupt router to get the interrupt from mcu domain. is there any configuration needed for the interrupt router? if yes is there any example provided by ti ,so that I can refer?

3.what is the correct number for the mcu_mcspi0 interrupt location? Or i can choose any location configured from interrupt router(255 to412)

4.How i can configure the interrupt router for my application

Thanks,
