Can you please guide to solve this issue. 

Please share your example.syscfg file with us to further analyze the issue.

Thank you for the response Tushar.

I have attached the main.c file and example.sysconfig file below for your reference.

Hi Nivetha,

Thanks for sharing the above details. 

Can you please confirm which boot flow are you using? Is it SBL or SPL?

Regards,

Tushar

Its SBL Boot flow

We are in a crucial situation. Please reply as much as possible.

I'm using GPIO1_0 (J3) for interrupt. As I told earlier, I'm trying to monitor the falling edge of the slave. 

SDK: 10.01.00.32

I followed all those steps in this link, after compiling through gmake command, host id is added in the sciclient_defaultBoardcfg_rm.c file.

configured sciclient_defaultBoardcfg_rm.c through sysconfig tool , images are attached below.

After this step, In my code I configured GPIO1_0 as the interrupt in example.sysconfig file. But the options available for interrupt router output is Router0 to 7. What are the missing steps here. I have attached my scicilient_gpioIrqSet() init part. In that, .dst_id should be TISCI_DEV_PRU_ICSSG0 (81U) right? 

My understanding : This "[Error] Sciclient event config failed!!!" error is due to .dst_id and .dst_host_irq. So I need to add the TISCI_HOST_ID_ICCSSG_0 host ID, since I'm using GPIO1_0 for interrupt. If I added the host (TISCI_HOST_ID_ICCSSG_0) in sciclient_defaultBoardcfg_rm.c file. .dst_id will get updated to TISCI_DEV_PRU_ICSSG0 (81U) and .dst_host_iq can be configured in example.sysconfig file. Does my understanding is right? Please correct me if I'm wrong.

If the flow is right, after configuring the sciclient_defaultBoardcfg_rm.c file, is there anything i need to do in example.sysconfig of codefile to change the .dst_id amd .dst_host_irq. 

Thanks is Advance.

Hello Nivetha,

The Sciclient_gpioIrqSet() API is autogenerated via Sysconfig tool. You do not need to change it.

Your Sciclient_gpioIrqSet() API should consist below code.

static void Sciclient_gpioIrqSet(void)
{
    int32_t                             retVal;
    struct tisci_msg_rm_irq_set_req     rmIrqReq;
    struct tisci_msg_rm_irq_set_resp    rmIrqResp;
    rmIrqReq.valid_params           = 0U;
    rmIrqReq.valid_params          |= TISCI_MSG_VALUE_RM_DST_ID_VALID;
    rmIrqReq.valid_params          |= TISCI_MSG_VALUE_RM_DST_HOST_IRQ_VALID;
    rmIrqReq.global_event           = 0U;
    rmIrqReq.src_id                 = TISCI_DEV_GPIO1;
    rmIrqReq.src_index              = TISCI_BANK_SRC_IDX_BASE_GPIO1 + GPIO_GET_BANK_INDEX(0);
    rmIrqReq.dst_id                 = TISCI_DEV_R5FSS0_CORE0;
    rmIrqReq.dst_host_irq           = CSLR_R5FSS0_CORE0_INTR_MAIN_GPIOMUX_INTROUTER0_OUTP_7;
    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, SystemP_WAIT_FOREVER);
    if(0 != retVal)
    {
        DebugP_log("[Error] Sciclient event config failed!!!\r\n");
        DebugP_assert(FALSE);
    }
    return;
}

You do not need to change the RM config file as the MAIN GPIOMUX Router 0 to 7 are already configured to R5F0-0 .
