 I am try use UART2 on my custom board on MCBSP3 pins.

 for it i am remaked bsp_padcfg.h like this:

//#define UART2_PADS \
//    PAD_ENTRY(UART2_TX , INPUT_DISABLED | MUXMODE(0))      \
//    PAD_ENTRY(UART2_RTS, INPUT_DISABLED | MUXMODE(0))      \
//    PAD_ENTRY(UART2_CTS, INPUT_ENABLED | PULL_RESISTOR_ENABLED | PULLUP_RESISTOR | MUXMODE(0))      \
//    PAD_ENTRY(UART2_RX , INPUT_ENABLED | PULL_RESISTOR_ENABLED | PULLUP_RESISTOR | MUXMODE(0))     

#define UART2_PADS \
    PAD_ENTRY(MCBSP3_CLKX , INPUT_DISABLED | MUXMODE(1))      \
    PAD_ENTRY(MCBSP3_DR, INPUT_DISABLED | MUXMODE(1))      \
    PAD_ENTRY(MCBSP3_DX, INPUT_ENABLED | PULL_RESISTOR_ENABLED | PULLUP_RESISTOR | MUXMODE(1))      \
    PAD_ENTRY(MCBSP3_FSX , INPUT_ENABLED | PULL_RESISTOR_ENABLED | PULLUP_RESISTOR | MUXMODE(1))   

But my uart2 doesn't working. It can send bytes but not receive.

it looks like I missed something in the initialization
please help

    The modifications you made seem fine but there might some other reasons why you can send but not receive data:

     - Some driver overrides you mux configuration (should not happen if you properly modified the reference BSP for your custom board)

     - Which test application are you using? Have tested this same application with another working UART?

     - What cable do you use and what device is on the other side?

     - Do you use flow control and is the device on the other side managing flow control and correctly wired to the CTS/RTS signals?

    2605.serail_uart.zip Hello thanks you for answer.

    this code used for check Pad Functional Multiplexing and Configuration regs and i trying loopbacking RX on TX.
    this code executed then in my application program then calling function CreateFile()

     hDrv2=CreateFile(L"COM2:",GENERIC_WRITE|GENERIC_READ,0,NULL,OPEN_EXISTING,0,NULL);
     

    now how my application looks:
    this is just simple code for sent and then read COM2.

    and loopbacking not working any more.
    if i remaked application like this:

    while(1){
        tcTemp1[0]= 0xEE;
        WriteFile(hDrv2,tcTemp1,1,&dwWritten,NULL);    

        tcTemp1[0]= 0x00;
        Sleep(1000);

        result = ReadFile(hDrv2,tcTemp1,LEN_FOR_CHECK,&dwRead,NULL);
            
            if(result==0)
            {
            printf("Failed ReadFile COM2  \r\n");
            }
        
            printf("ReadFile dwRead=%d  \r\n",dwRead);

        printf("tcTemp1[0] = %x  \r\n",tcTemp1[0]);
        }

    telnet output:

    This is WORKING =). Looks like COM_Close() are broke driver. or driver just not reinited on COM_Open() properly.    

    Any help? TY.
        
        
    i am attach my test applications tc2.exe and tc2l.exe
    You can just try it by short RX on TX by external wire on you com port 2
    You need short 2 pin on 3 pin on DB9.
    Or you can add SETREG8(&pPdd->pUartRegs->MCR, UART_MCR_LOOPBACK_EN);
    in driver code.

    i  fix it

    need add code for reinit RxDMA  in HWOpen.

    like this:

       if (pPdd->open) goto cleanUp;

        // We have set hardware to D0
        pPdd->externalDX = D0;
        SetPower(pPdd, D0);

    //================
    //EAI ADDON

            // Rx DMA configuration settings
        InitializeRxDMA(pPdd);
        EnterCriticalSection(&pPdd->hwCS);

        pPdd->bRxDMASignaled = 0;
        pPdd->bRxWrapped     = FALSE;
        pPdd->pRxDMALastWrite = 0;
        pPdd->bDmaInitialize = FALSE;


    RETAILMSG(1, (L"HWInit: pPdd->UARTIndex: 0x%08x\r\n", pPdd->UARTIndex));
    RETAILMSG(1, (L"HWInit: pPdd->memBase[0]: 0x%08x\r\n", pPdd->memBase[0]));
    RETAILMSG(1, (L"HWInit: pPdd->irq: 0x%08x\r\n", pPdd->irq));
    RETAILMSG(1, (L"HWInit: pPdd->pUartRegs 0x%08x\r\n", pPdd->pUartRegs));

        InitializeUART(pPdd);

        LeaveCriticalSection(&pPdd->hwCS);

    //EAI
    //================

       SetDefaultDCB(pPdd);

        pPdd->commErrors    = 0;
        pPdd->overrunCount  = 0;
        pPdd->flowOffCTS    = FALSE;
        pPdd->flowOffDSR    = FALSE;
        pPdd->addTxIntr     = FALSE;
        pPdd->open          = TRUE;
        pPdd->wakeUpMode    = FALSE;
        pPdd->RxTxRefCount  = 0;
        pPdd->bExitPowerThread = FALSE;
