    Hi Lubo,

    There is no hardware watchdog design on UP4000.

    I would like to ask if what you need is the watchdog function?
    Or is it necessary to have a watchdog in hardware?

    Best Regards,
    Wilbert Lee.

    I use UP boards in role of process controller. We have customers IO board attached via 40 pin connector to it. We controll tochnology and is important to ensure that in case of any reason that our application is not running, to stop power and engines - which is ensured by hw independet reseting of IO hardware in the case that something went wrong.... ( there is safety default outputs hw state after reset ensured by hw of this IO board , and it remains until UP starts our control software and enable power for engines.... ).... This is why we have hw wathdog in this custom IO board implemented currently...
