      Hello there,

      I am facing with a weird issue again.
      My wipy restart from time to time.
      machine.reset_cause() returns with 2 which is wdt_reset, but there is no watchdog object created in my code.
      Could this watchdog coming from pybytes or is it coming from Baskerville?
      Is there a way to find it?

        @tttadam what does the following code return pycom.wdt_on_boot() ? It may be the case that the watchdog has been configured previously by another code. If this is True, set it to False, reboot the device and you're ok.

          @agotsis It was False, I set it false again. So probably it was not it.

            Picture for proof :)
            There is no watchdog in the code neither.

              @tttadam I would then propose to have a full flash erase of your module and see if the problem is still there (I know this is no actual solution, but has worked for me when I am seeing strange behavior)

                I did that.
                Updated the firmware with pycom firmware updater, erased everything during the process.
                BUT still reboots from time to time...

                    So I repetead the process again, now I change the filesytem also. No more bootloop.
                    We will see about the watchdog.
