Can't set TDO or TDI Pins low or High on CC3200

Hi Folks,

  I have a CC3200 Module  in our design.  We are using SWD mode to debug the chip, and the TDO and TDI pins are being used for a UART (UART1).  If I run it in UART mode it works fine.  But if I try to turn the UART pins into GPIO pins I cannot get the TDO or TDI pins to be controllable as GPIO pins.  I have even bypassed any UART mode and defined the pins as GPIO outputs and it still doesn't work.  My code in pin_mux_config.c is as follows:

    PinTypeGPIO(PIN_16, PIN_MODE_0, false);
    GPIODirModeSet(GPIOA2_BASE, 0x80, GPIO_DIR_MODE_OUT);


    PinTypeGPIO(PIN_17, PIN_MODE_0, false);
    GPIODirModeSet(GPIOA3_BASE, 0x1, GPIO_DIR_MODE_OUT);

I have tried various ways to get the pins to go up and down, and none have worked.  Here is the code I am using to try to get the pins to go from low to high, etc...

        // Pin 18
	GPIO_IF_GetPortNPin(24, &vaddr, &vpin);
        GPIO_IF_Set(24, vaddr, vpin, 0);    /// '1' for HIGH; '0' for LOW
        GPIO_IF_Set(24, vaddr, vpin, 1);    /// '1' for HIGH; '0' for LOW

        // Pin 12
        GPIO_IF_GetPortNPin(23, &vaddr, &vpin);
        GPIO_IF_Set(23, vaddr, vpin, 0);    /// '1' for HIGH; '0' for LOW
        GPIO_IF_Set(23, vaddr, vpin, 1);    /// '1' for HIGH; '0' for LOW

        MAP_GPIOPinWrite(GPIOA3_BASE,0x1, 0x1);

        MAP_GPIOPinWrite(GPIOA3_BASE,0x1,0);

          MAP_GPIOPinWrite(GPIOA2_BASE,0x80, 0x80); 

          MAP_GPIOPinWrite(GPIOA2_BASE,0x80,0);

Neither of these methods get the TDO or TDI pin to move as a GPIO.

Any suggestions as to what I can do to get this pin to be usable as a GPIO pin?

Thanks,

Vic
