Any mistake in the boot code risks the system getting stuck (at least until the battery goes flat). A watchdog and user button can be combined to give a long-press reset that gives the user a better shot at recovering the device before the battery runs down!	2020-01-20 08:01:24 +00:00

nrf: Feed the watchdog from the RTC interrupt

Feeding a watchdog from a periodic interrupt isn't the smartest thing
to do (unless you have setup multi-channels) so we also allow us to
express to the WDT driver whether we've arrived from an ISR or not.

nrf: Initial WDT-in-C implementation

Currently it is difficult to deploy uPy on form factor devices without
a reset pin. Any mistake in the boot code risks the system getting
stuck (at least until the battery goes flat). A watchdog and user
button can be combined to give a long-press reset that gives the user
a better shot at recovering the device before the battery runs down!
