The example works. That is, when you execute the program it shows the "1" for high state and when you ground pin P8_07 it shows "0" instead. After exiting the main loop (by pressing any key), the program tries to restore the original state of the pin. And this re-configuration fails, since Gpio->config() doesn't handle PRUIO_PIN_RESET correctly. This issue is already fixed for the next release. You can ignore it, as long as you don't need to reconfigure the pin. Otherwise, if you need a specific pin configuration after executing the example, you can work around by replacing PRUIO_PIN_RESET by the desired configuration (or use .BallInit(PIN) for the original state).
