AM5728: 如何在DSP 端，使用SYSBIOS创建基于uart的硬件中断

void hwiFunc(UArg arg)
{
    unsigned char   rxData      = 0;

    //在中断服务程序中清中断
    //Hwi_clearInterrupt(7);

    /* Checking ths source of UART interrupt. */
    int32_t intId = UARTIntIdentityGet(SOC_UART1_BASE);

    Log_print1(Diags_ENTRY, "UARTIsr: %d", intId);

    switch (intId)
    {
        case UART_INTID_TX_THRES_REACH:
            Log_print0(Diags_ENTRY, "UART_INTID_TX_THRES_REACH");
            break;

        case UART_INTID_RX_THRES_REACH:
            rxData = UARTCharGetNonBlocking(SOC_UART1_BASE);
            //UARTCharPutNonBlocking(uartBaseAddr, rxByte);

            Log_print1(Diags_ENTRY, "Rx: %02x", rxData);
            break;

        case UART_INTID_RX_LINE_STAT_ERROR:
        case UART_INTID_CHAR_TIMEOUT:
            rxData = UARTCharGetNonBlocking(SOC_UART1_BASE);
            if(intId == UART_INTID_CHAR_TIMEOUT)
                Log_print1(Diags_ENTRY, "UART_INTID_CHAR_TIMEOUT: %02x", rxData);
            else
                Log_print1(Diags_ENTRY, "UART_INTID_RX_LINE_STAT_ERROR: %02x", rxData);
            break;

        default:
            break;
    }
}

void Hwi_Init(void)
{
    Log_print0(Diags_ENTRY, "Hwi_Init");

    //创建中断
    Hwi_Handle hwi_uart1;         //句柄
    Hwi_Params hwi_params;        //传入参数
    Error_Block eb;               //错误块

    Error_init(&eb);              //错误块初始化，注意必须初始化，否则易进入System_abort
    Hwi_Params_init(&hwi_params); //初始化传入参数
    hwi_params.eventId = 43;
    hwi_params.enableInt = TRUE;
    //hwi_params.maskSetting = Hwi_MaskingOption_SELF;      // don't allow this interrupt to nest itself
    hwi_uart1 = Hwi_create(7, hwiFunc, &hwi_params, &eb); //注意此处id是中断等级编号，如中断5，则id为5

    if(hwi_uart1 == NULL)
    {
        System_abort("hwi_uart1 create failed");
    }
    
    Hwi_enableInterrupt(7);       //使能中断
}

PDK_INSTALL_PATH\packages\ti\drv\uart\UART.h 的库函数配置串口？
