MTK6260M串口2调GPS驱动求助

514175575

直接用串口接线出来能在电脑上打印出GPS发送的数据，但是通过程序无法收到接收消息，下面是我写的uart2初始化设置函数，每个分支都试过了，都不行(trace打印系统不会调用我的myapp_gps_uart_rx_cb)，求大神帮看下：

#define GPS_UART_PORT        uart_port2
#define GPS_UART_OWNERID ((module_type)(MOD_UART1_HISR + GPS_UART_PORT))

static void myapp_gps_uart_init(void)
{
        myapp_trace("myapp_gps_uart_init");
#if 0
        UART_DriverInit(GPS_UART_PORT, 0);
        UART_PDN_Disable(GPS_UART_PORT); //串口休眠控制
        //U_SetBaudRate(GPS_UART_PORT, UART_BAUD_9600, (module_type)(MOD_UART1_HISR + GPS_UART_PORT));
        U_Register_RX_cb( GPS_UART_PORT, (module_type)(MOD_UART1_HISR + GPS_UART_PORT), myapp_gps_uart_rx_cb);
        U_Register_TX_cb( GPS_UART_PORT, (module_type)(MOD_UART1_HISR + GPS_UART_PORT), myapp_gps_uart_tx_cb);
        U_ClrRxBuffer(GPS_UART_PORT, UARTPort[GPS_UART_PORT].ownerid);  /*clear sw RX buffer*/
        U_ClrTxBuffer(GPS_UART_PORT, UARTPort[GPS_UART_PORT].ownerid);  /*clear sw TX buffer*/
        U_Purge(GPS_UART_PORT, RX_BUF, UARTPort[GPS_UART_PORT].ownerid);/*clear sw RX FIFO*/
        U_Purge(GPS_UART_PORT, TX_BUF, UARTPort[GPS_UART_PORT].ownerid);/*clear sw TX FIFO*/
#else
        #if 0
        U_SetOwner(GPS_UART_PORT, (module_type)(MOD_UART1_HISR + GPS_UART_PORT));
        UART_PDN_Disable(GPS_UART_PORT);
       U_SetBaudRate(GPS_UART_PORT, UART_BAUD_9600, (module_type)(MOD_UART1_HISR + GPS_UART_PORT));
        mmi_frm_set_protocol_event_handler(MSG_ID_UART_READY_TO_READ_IND, cl_ready_read_ind, MMI_TRUE);
        U_Register_RX_cb( GPS_UART_PORT, (module_type)(MOD_UART1_HISR + GPS_UART_PORT), myapp_gps_uart_rx_cb);
        U_Register_TX_cb( GPS_UART_PORT, (module_type)(MOD_UART1_HISR + GPS_UART_PORT), myapp_gps_uart_tx_cb);
        UART_TurnOnPower(GPS_UART_PORT, KAL_TRUE);
        if (U_Open(GPS_UART_PORT, (module_type)(MOD_UART1_HISR + GPS_UART_PORT)))
                myapp_trace("uart2 open success");
        else
                myapp_trace("uart2 open fail");
        //U_Open(GPS_UART_PORT, (module_type)(MOD_UART1_HISR + GPS_UART_PORT));
        U_ClrRxBuffer(GPS_UART_PORT, UARTPort[GPS_UART_PORT].ownerid);  /*clear sw RX buffer*/
        U_ClrTxBuffer(GPS_UART_PORT, UARTPort[GPS_UART_PORT].ownerid);  /*clear sw TX buffer*/
        U_Purge(GPS_UART_PORT, RX_BUF, UARTPort[GPS_UART_PORT].ownerid);/*clear sw RX FIFO*/
        U_Purge(GPS_UART_PORT, TX_BUF, UARTPort[GPS_UART_PORT].ownerid);/*clear sw TX FIFO*/
        #else
        UART_TurnOnPower(GPS_UART_PORT, KAL_TRUE);
        if (U_Open(GPS_UART_PORT, GPS_UART_OWNERID))
                myapp_trace("uart2 open success");
        else
                myapp_trace("uart2 open fail");
        myapp_gps_uart_configure(9600, GPS_UART_PORT, GPS_UART_OWNERID);
        U_ClrRxBuffer(GPS_UART_PORT, GPS_UART_OWNERID);
        U_Register_RX_cb( GPS_UART_PORT, GPS_UART_OWNERID, myapp_gps_uart_rx_cb);
        U_Register_TX_cb( GPS_UART_PORT, GPS_UART_OWNERID, myapp_gps_uart_tx_cb);
        mmi_frm_set_protocol_event_handler(MSG_ID_UART_READY_TO_READ_IND, myapp_ready_read_ind, MMI_TRUE);
        #endif
#endif
}

我做过类似的项目，11A版本，你留Q我联系你

这个要配置的吗？在drv tool里面配置吗

串口的IO配置对了吗

遇到和楼主一样的问题，不知道你遇到的问题是什么原因？能否告诉我一下。
