AWR1642BOOST: CAN传输函数

zhao hao

Part Number: AWR1642BOOST

我的CAN传输代码如下：在正常初始化以及赋值给了 appDcanTxData数据之后，运行时在下面绿色函数内发生异常

int32_t Can_Transmit_Schedule(uint8_t *txmsg,
                              uint32_t len)
{
    volatile uint32_t index   = 0;
    int32_t           retVal = 0;
    int32_t           errCode = 0;
    CAN_DCANData      appDcanTxData;
    int32_t           x = 0;

    // System_printf ("MEssage %x len %d\n", msg_id, len);
    Task_sleep(1);
    while (len > 8U)
    {
        appDcanTxData.dataLength = 8U;
        memcpy(appDcanTxData.msgData, &txmsg[index], 8U);
        retVal = CAN_transmitData(txMsgObjHandle, &appDcanTxData, &errCode);
        if (retVal < 0)
        {
            continue;
        }
        index = index + 8U;
        len   = len - 8U;
        x++;
    }

    if (len > 0)
    {
        appDcanTxData.dataLength = len;
        memcpy(appDcanTxData.msgData, &txmsg[index], len);

        retVal = CAN_transmitData(txMsgObjHandle, &appDcanTxData, &errCode);

        while (retVal < 0)
        {
            // System_printf("Debug: Error transmitting CAN data %x , Errcode %x\n", retVal, errCode);
            retVal = CAN_transmitData(txMsgObjHandle, &appDcanTxData, &errCode);
        }
    }

    return retVal;
}
