RTOS/LAUNCHXL-CC2650: Facing issue while accessing COMport

Tool/software: TI-RTOS

Hello,

I am using CC2650 debugger and it is connected to another board. The data sheet of the board has Rx_Tx pin connected to a radio. So it doesnot have any usable Rx or Tx pin.

Can i use any open pins which are connected cc2650 as Rx and Tx pin?

I tried using pin 6 and 7 which are connected to IOID_0 and IOID_1 respectively. I changed the rx and tx pins in uartCC26XXHWAttrs[CC2650_LAUNCHXL_UARTCOUNT] in the LAUNCHXL_CC2650.c file 

/* UART hardware parameter structure, also used to assign UART pins */
const UARTCC26XX_HWAttrsV2 uartCC26XXHWAttrs[CC2650_LAUNCHXL_UARTCOUNT] = {
    {
        .baseAddr       = UART0_BASE, //Assuming it is the same for both the boards
        .powerMngrId    = PowerCC26XX_PERIPH_UART0,
        .intNum         = INT_UART0_COMB,
        .intPriority    = ~0,
        .swiPriority    = 0,
        .txPin          = IOID_0,  //Board_UART_TX, //Might need to change
        .rxPin          = IOID_1,  //Board_UART_RX, //Might need to change
        .ctsPin         = PIN_UNASSIGNED,
        .rtsPin         = PIN_UNASSIGNED,
        .ringBufPtr     = uartCC26XXRingBuffer[0],
        .ringBufSize    = sizeof(uartCC26XXRingBuffer[0])
    }
};

I do not see anything on the comport. And I am using Board_UART0 itself as the index. Can someone suggest me if I have to change the index? or/and change rx/tx pin or/and do I have to make any more changes?

Thanks,

Rathna
