LAUNCHXL-CC1310: Hwi exception when adding UART driver to out of the box example

Hi,

I am trying to add UART support to the WOR example (using TI-RTOS).

On the top of the rfWakeOnRadioRx.c fiel I have added the #include <ti/drivers/UART.h> and the UART_Handle global (and static) variable:

#include <ti/drivers/UART.h>

#if defined(BOARD_DISPLAY_USE_UART)
static UART_Handle hUART;
#endif

And inside main.c I have added the following lines:

int main(void)
{

    /* Call driver init functions. */
    Board_initGeneral();

    /* Open LED pins */
    ledPinHandle = PIN_open(&ledPinState, pinTable);
    Assert_isTrue(ledPinHandle != NULL, NULL);

#if defined(BOARD_DISPLAY_USE_UART)                // ADDED UART INITIALIZATION
    /* Enable System_printf(..) UART output */
    UART_init();
    UART_Params uartParams;
    UART_Params_init(&uartParams);
    uartParams.baudRate      = 115200;
    uartParams.writeMode     = UART_MODE_BLOCKING;
    uartParams.readMode     = UART_MODE_BLOCKING;
    uartParams.writeDataMode = UART_DATA_BINARY;
    uartParams.readDataMode  = UART_DATA_BINARY;
    uartParams.readEcho      = UART_ECHO_OFF;
    hUART = UART_open(Board_UART0, &uartParams);
    if (!hUART){
        while(1);
    }
#endif /* BOARD_DISPLAY_USE_UART */


    UART_write(hUART, "Hello", 4);   // TRY TO SEND SOMETHING -> HERE THE EXCEPTION OCCURS

    /* Initialize task */
    rxTaskInit();

    /* Start BIOS */
    BIOS_start();

    return (0);
}

In ROV I just see that the exception occurred:

But with no decoded information nor exception call stack (symbol is not available) although I have the full exception decoding enabled:

Besides all that, the Board_initGeneral(); function call configure the CC1310 launchpad pins so the UART should be just work, right?

what am I missing?

Thanks
