Hi Aaron,

Please make sure the start address of the code is at address 0x000000. We have different variant, one is without softdevice (start at 0x00) and one to be used with softdevice (starts at 0x??? ). There is a chance that you flashed the variant with softdevice and that's why it didn't erase the old application.

I think something in these functions is the critical issue because I copied and pasted them into a working project and now that project will not load onto the board.

void in_pin_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
    nrf_drv_gpiote_out_toggle(PIN_OUT);
}

/**
 * @brief Function for configuring: PIN_IN pin for input, PIN_OUT pin for output, 
 * and configures GPIOTE to give an interrupt on pin change.
 */
static void gpio_init(void)
{
    ret_code_t err_code;

    err_code = nrf_drv_gpiote_init();
    APP_ERROR_CHECK(err_code);
    
    nrf_drv_gpiote_out_config_t out_config = GPIOTE_CONFIG_OUT_SIMPLE(false);

    err_code = nrf_drv_gpiote_out_init(PIN_OUT, &out_config);
    APP_ERROR_CHECK(err_code);

    nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);
    in_config.pull = NRF_GPIO_PIN_PULLUP;

    err_code = nrf_drv_gpiote_in_init(PIN_IN, &in_config, in_pin_handler);
    APP_ERROR_CHECK(err_code);

    nrf_drv_gpiote_in_event_enable(PIN_OUT, true);
}
