Hello Elfving,

Thanks for your response. I was just working on my job assignment to test the watchdog and i saw the

int wdt_disable(const struct device *dev) function.

It is okay if wdt cannot be disabled

Thanks,

Joseph

Hello Joseph!

What you are trying to do here is disabling the watchdog from the application, which is against its purpose. The purpose of a watchdog is to ensure that your program continuously feeds it in order to verify that your program runs as it should. I wouldn't recommend disabling it in runtime, and it is not something the function should allow you to either. Error -1 is the "Not Owner" error, it is not letting you.

If you want to experiment with using the watchdog I would recommend you to move the if statement to rather turn the watchdog on if the user_command == "enable watchdog", instead of turning it off.

Best regards,

Elfving
