I am looking for a UART driver with Interrupt for MPC5748G micro but you have shared for MPC5775K.

Please provide the required project

[Anilpatil_SasvaAuto]

My requirement: Transmit and receive 9 bytes of hex values as shown below.
TxBuffer[9] = {0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19}

URGENT!!: Please provide an example code for the MPC5748G EVB board with Tx & Rx interrupt for my requirement.
This change will be used in our production program (FORD OEM).

Please provide the procedure to test your example code

Please review my Uart7_Rx_Isr code below:

void Uart7_Rx_Isr (void)

{

    unsigned char Channel = 7U;

    unsigned char Data;

    if (1 == LINFlexD_7.UARTSR.B.DRFRFE)

    {

        Data = LINFlexD_7.BDRM.B.DATA4;

        LINFlexD_7.UARTSR.R &= UART_DRFRFE;      /* Clear data reception flag W1C */

       /*Save received data*/

       if (BufferTxdisplay_index < UART_7_TX_MAX_LENGTH)   //0 <12

      {

           BufferTxdisplay[BufferTxdisplay_index] = Data;

           BufferTxdisplay_index++;

      }

     if( (BufferTxdisplay_index >= 9) )

     {

        BufferTxdisplay_index = 0;

     }

   }

}

I am attempting to read all 9 bytes using the above Rx ISR, but I am only receiving the first byte repeatedly, which is 0x11.

Expected Output:

TxBuffer[9] = {0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19};

RxBuffer[9] = {0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19};

Actual Output:

TxBuffer[9] = {0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19};

RxBuffer[9] = {0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11};

Could you please suggest what the issue is in the RxISR routine?

Please provide the correct Uart7_Rx_Isr routine to read valid 9 bytes and Uart7_Tx_Isr and Transmit function as well.
