C.1 Introduction to Watchdog Timer
This section details how to set up and program the Watchdog Timer for your AAEON
system or board. The watchdog timer is used to automatically detect malfunctions and
recover the system. During normal operation, the system will regularly send a signal to
reset the watchdog timer. If the system does not reset the watchdog timer, it will
timeout and force the system into recovery and/or reboot.
The following sections refer to additional software used for programming your board,
such as the AAEON Framework, AAEON SDK and AAEON Windows EAPI. If you need
assistance with utilizing these tools, programming your Watchdog Timer, or would like
additional documentation on these resources, contact your AAEON representative or
