You should then see a solid LED. Pressing button 1 will cause the DFU to be loaded by the bootloader. Upon
successfully loading, you'll see the LED flash. After 5 seconds, because there is no petting of the watchdog,
you'll see the LED go solid again. This indicates that the bootloader has reverted the update.
