Thank you for your patience. We’ve investigated about your case and found out that the Edison does not have general purpose watchdog timers. Additional to this,we also received an alternative option for you. The option would be to use an external watchdog component and connect into the SoC GPIO and PMIC reset signals for monitoring of events.
Please let us know if this is useful and if there’s anything else we can do to assist you.
