A hardware watchdog monitors whether a system or application is still responding regularly. To do this, the running system must reset the watchdog timer at defined intervals. If this signal does not occur, the watchdog triggers a restart or hardware reset, depending on the device and configuration.
The implementation and function of the watchdog vary depending on the RevPi device.
