Watchdog

Watchdog is a function to let the device automatically reset if a program

does not respond in time. This prevents system crashes and hangs to stop

your critical applications, as the watchdog will automatically restart the

machine when required.

Set the response time through the combo box as shown below. The timer

is the period that the watchdog will wait for a response.

Figure 4.7: Watchdog Setting

Only when you select a time span and enable the watchdog, will the

response time be effective. When the watchdog is enabled and the "Test"

button is clicked, the NO resetting signal will be periodically sent to the

watchdog hardware onboard. The watchdog will suppose the machine to

be deadlocked and REBOOT it after the watchdog response time. If the

machine reboots as expected after the watchdog response time, the watch-

dog is proved to be working properly.
