CC2652RB: Dual UART Problem

Part Number: CC2652RB

Hi,

I am try to init both UARTS of CC2652RB. 

But only one of the INIT is ok, when one is opened the other won't open. I think there is some kind of conflict but can't figure out.

Here are the codes, init structures etc.

void UART0_init(int first)
{

    volatile int x=0;
       UART_Params uartParams;

       /* Create a UART with data processing off. */
       UART_Params_init(&uartParams);
       uartParams.writeDataMode = UART_DATA_BINARY;
       uartParams.readDataMode = UART_DATA_BINARY;
       uartParams.readReturnMode = UART_RETURN_FULL;
       uartParams.readEcho = UART_ECHO_OFF;
       uartParams.readMode = UART_MODE_CALLBACK;
       uartParams.readCallback = &UART0_readCallback;
       uartParams.baudRate = 115200;
       uartParams.writeMode = UART_MODE_CALLBACK;
       uartParams.writeCallback = &UART0_writeCallback;
       h_uart_0 = UART_open(CONFIG_UART_0, &uartParams);

       if (h_uart_0 == NULL)
       {
          System_abort("Error opening the UART0");
          x=1;
       }

      UART_read(h_uart_0, input, 1); //activate a read 

}


void UART1_init(void)
{
    volatile int x=0;
    UART_Params uartParams1;

    /* Create a UART with data processing off. */
    UART_Params_init(&uartParams1);
    uartParams1.writeDataMode = UART_DATA_BINARY;
    uartParams1.readDataMode = UART_DATA_BINARY;
    uartParams1.readReturnMode = UART_RETURN_FULL;
    uartParams1.readEcho = UART_ECHO_OFF;
    uartParams1.readMode = UART_MODE_CALLBACK;
    uartParams1.readCallback = &UART1_readCallback;
    uartParams1.baudRate = 115200;
    uartParams1.writeMode = UART_MODE_CALLBACK;
    uartParams1.writeCallback = &UART1_writeCallback;
    h_uart_1 = UART_open(CONFIG_UART_1, &uartParams1);

    if (h_uart_1 == NULL)
    {
       System_abort("Error opening the UART 1");
       x=1;
    }


   UART_read(h_uart_1, inputx, 1); //activate a read 

}

Here is the code generated for the structs from SYSCFG, there is no PIN conflict or device conflict.
