TDA4AH-Q1: How to configure MCAN to interrupt transmission and reception mode in MCU 1_0?

Hello,

I use demo is ti-processor-sdk-rtos-j721e-evm-09_02_00_05/pdk_jacinto_09_02_00_30/packages/ti/csl/example/mcan/mcanEvmLoopback/mcan_evm_loopback_app_main_k3.c.

At present, MCU_MCAN0 is called in MCU2_1 core. After the interrupt is enabled, the interrupt does not take effect. The code is modified as follows:

static void App_mcanIntr0ISR(uintptr_t arg)
{
    uint32_t intrStatus;
    gMcanModAddr = gMcanDiagPortInfo[0].mcanBaseAddr;
    intrStatus = MCAN_getIntrStatus(gMcanModAddr);
    MCAN_clearIntrStatus(gMcanModAddr, intrStatus);
    printf("App_mcanIntr0ISR ===%x.\n",intrStatus);
    tx_counter++;
    if (MCAN_INTR_SRC_TRANS_COMPLETE ==
        (intrStatus & MCAN_INTR_SRC_TRANS_COMPLETE))
    {
        gMcanIsrIntr0Flag = 0U;
        printf("App_mcanIntr0ISR 0000000000.\n");
    }

    if (MCAN_INTR_SRC_DEDICATED_RX_BUFF_MSG ==
        (intrStatus & MCAN_INTR_SRC_DEDICATED_RX_BUFF_MSG))
    {
        gMcanIsrIntr1Flag = 0U;
        printf("App_mcanIntr0ISR 111111111111.\n");
    }

}


static void App_mcanIntr1ISR(uintptr_t arg)
{
    uint32_t intrStatus;
    gMcanModAddr = gMcanDiagPortInfo[0].mcanBaseAddr;
    intrStatus = MCAN_getIntrStatus(gMcanModAddr);
    MCAN_clearIntrStatus(gMcanModAddr, intrStatus);
    printf("App_mcanIntr1ISR ===%x.\n",intrStatus);
    rx_conuter++;
    if (MCAN_INTR_SRC_DEDICATED_RX_BUFF_MSG ==
        (intrStatus & MCAN_INTR_SRC_DEDICATED_RX_BUFF_MSG))
    {
        gMcanIsrIntr1Flag = 0U;
        printf("App_mcanIntr1ISR 0.\n");
    }

}

static void App_mcanTSIntrISR(uintptr_t arg)
{
    printf("Time Stamp overflow happened.\n");
}

static int32_t App_mcanRegisterIsr(void)
{
    int32_t configStatus = STW_SOK;
    /* MCU MCAN Inst 0 */
    configStatus =  App_mcanRegisterInterrupt(APP_MCU_MCAN_0_INT0, &App_mcanIntr0ISR);
    configStatus += App_mcanRegisterInterrupt(APP_MCU_MCAN_0_INT1, &App_mcanIntr1ISR);
    configStatus += App_mcanRegisterInterrupt(APP_MCU_MCAN_0_TS_INT, &App_mcanTSIntrISR);
}

static void BoardDiag_mcanRxIntEnable(uint32_t baseAddr)
{
    /* Enable Interrupts */
    MCAN_enableIntr(baseAddr, MCAN_INTR_MASK_ALL, (uint32_t)TRUE);
    MCAN_enableIntr(baseAddr,
                    MCAN_INTR_SRC_RES_ADDR_ACCESS, (uint32_t)FALSE);
    /* Select Interrupt Line */
    MCAN_selectIntrLine(baseAddr,
                        MCAN_INTR_MASK_ALL,
                        MCAN_INTR_LINE_NUM_1);
    /* Enable Interrupt Line */
    MCAN_enableIntrLine(baseAddr,
                        MCAN_INTR_LINE_NUM_1,
                        1U);
}

/**
 * \brief   This API will enables the TX interrupts
 *
 * \param   baseAddr  [IN]  MCAN base address
 *
 */
static int32_t BoardDiag_mcanTxIntEnable(uint32_t baseAddr)
{
    int32_t  status = 0;
    MCAN_enableIntr(baseAddr, MCAN_INTR_MASK_ALL, (uint32_t)TRUE);
    MCAN_enableIntr(baseAddr,
                    MCAN_INTR_SRC_RES_ADDR_ACCESS, (uint32_t)FALSE);
    /* Select Interrupt Line */
    MCAN_selectIntrLine(baseAddr,
                        MCAN_INTR_MASK_ALL,
                        MCAN_INTR_LINE_NUM_0);
    /* Enable Interrupt Line */
    MCAN_enableIntrLine(baseAddr,
                        MCAN_INTR_LINE_NUM_0,
                        1U);
    /* Enable Transmission interrupt */
    status = MCAN_txBufTransIntrEnable(baseAddr,
                                       1U,
                                       (uint32_t)TRUE);
    return status;
}


init code :
                /* Set base address */
            uint32_t baseAddr = gMcanDiagPortInfo[portNum].mcanBaseAddr;
            
            Intc_Init();    
            /* Interrupt handler initialized, here as other functions can use API's to clear pending interrupts if any*/

            App_mcanRegisterIsr();

            BoardDiag_mcanTxIntEnable(baseAddr);

            BoardDiag_mcanRxIntEnable(baseAddr);
            

After completing the initialization mentioned above, a message was sent to MCU_MCAN0 externally, but the RX interrupt function of MCU_MCAN0 did not enter.

Question:

Is it possible to use MCU_SCAN0 interrupts in the MCU2_1 core? I see in the demo code that using MCU_MCAN0 is with BUILD_MCU1_0 enabled.

hello,

use MCU_MCAN0 for MCU2_1,How to use interrupt routing?Please provide guidance.

Hello,

Please allow me some time to elaborate.
