MTK 串口无波形

平台：MT2503D  
我是直接在 MMI_task 中注入的测试代码，测试硬件串口上没有波形，是不是串口需要硬件配置IO口的?   
问题解决，是IO口的模式没配，可以有drgen来配也可以用IO的序号配。下列代码可以用来学习串口配置和通讯，没有用任务扑捉事件！
catcher 抓到的log 如下，写入的返回值是9   

   测试代码如下：
void sl_test_init(void) {
#if 1  /* TEST SERIAL */
  {
     DCL_STATUS status;
    {
      handle  = DclSerialPort_Open(UART_port1, 0);
      __sl_trace("Handle :%d", handle);
    }
    //power on and open
    {
      UART_CTRL_POWERON_T power_ctl;
      power_ctl.bFlag_Poweron = true;
      DclSerialPort_Control(handle, UART_CMD_POWER_ON, (DCL_CTRL_DATA_T*)&power_ctl);
        __sl_trace("poweron ok");
    }
    //open
    {
      UART_CTRL_OPEN_T open_ctl;
      open_ctl.u4OwenrId = MOD_MMI;
      status = DclSerialPort_Control(handle, SIO_CMD_OPEN, (DCL_CTRL_DATA_T*)&open_ctl);
      if (STATUS_OK ！= status) {
        __sl_trace("open port failed:%d", status);
      }
    }
    //config
    {
      UART_CTRL_DCB_T config;
      config.u4OwenrId = MOD_MMI;
      config.rUARTConfig.u4Baud = UART_BAUD_115200;
      config.rUARTConfig.u1DataBits = LEN_8;
      config.rUARTConfig.u1StopBits = SB_1;
      config.rUARTConfig.u1Parity = PA_NONE;
      config.rUARTConfig.u1FlowControl = FC_NONE;
      config.rUARTConfig.ucXonChar = 0x11;
      config.rUARTConfig.ucXoffChar = 0x13;
      config.rUARTConfig.fgDSRCheck = (DCL_BOOLEAN)KAL_FALSE;
      status = DclSerialPort_Control(handle, SIO_CMD_SET_DCB_CONFIG, (DCL_CTRL_DATA_T*)&config);
      if (STATUS_OK ！= status) {
        __sl_trace("config port failed:%d", status);
      }
    }
    //check owner id
    {
        UART_CTRL_OWNER_T iddata;
        DclSerialPort_Control(handle, SIO_CMD_GET_OWNER_ID, (DCL_CTRL_DATA_T*)&iddata);
        __sl_trace("owner ID:%d,MMI_ID:%d", (module_type)(iddata.u4OwenrId),MOD_MMI);
    }
    //write the first package
    {
      UART_CTRL_PUT_BYTES_T wdata;
      wdata.u4OwenrId = MOD_MMI;
      wdata.u2Length = 9;
      wdata.puBuffaddr = "Hello world";
      DclSerialPort_Control(handle, SIO_CMD_PUT_BYTES, (DCL_CTRL_DATA_T*)&wdata);
      __sl_trace("Write :%d", wdata.u2RetSize);
    }
    StartTimer(SLUAN_TIMER_ID_1, 5000, sl_test_timer_cb);
  }
#endif
}
