Is there some kind of watchdog available on Opta? The tutorial https://docs.arduino.cc/tutorials/opta/getting-started-connectivity states a relationship to Portenta H7 Opta™ uses the same architecture as the Portenta H7 and therefore, it could be a good idea to take a look at the Portenta H7 tuto…

This works on Opta. void setup() { mbed::Watchdog::get_instance().start(10000); } void loop() { mbed::Watchdog::get_instance().kick(); }

I think it is safe to say that all modern microprocessors have a watchdog of some sort. The processor data sheet will give all the details.

Because Opta is based on same processor as Portenta H7 which runs Arduino Sketches on top of mbed OS maybe this is what you are looking for: https://os.mbed.com/docs/mbed-os/v6.16/mbed-os-api-doxy/classmbed_1_1_watchdog.html I have not testet this and I am no expert in Arduino architecture

Do you have any resource you can point me to to understand this?
What does .kick() do, does it reset the watchdog timer or stop it completely?
