    By default GPIO23 is in an analog mode that needs to be turned off before you can use it as a regular output. You can add the following to your GPIO set up.

      GPIO_setAnalogMode(DEVICE_GPIO_PIN_LED2, GPIO_ANALOG_DISABLED);

    Have you also added _LAUNCHXL_F280049C to your predefined symbols so that DEVICE_GPIO_PIN_LED2 is set to 23?
