Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0 Move to CMake 3.20.0. At the Toolchain WG it was decided to move to CMake 3.20.0. The main reason for increasing CMake version is better toolchain support. Better toolchain support is added in the following CMake versions: - armclang, CMake 3.15 - Intel oneAPI, CMake 3.20 - IAR, CMake 3.15 and 3.20 Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>		2021-08-20 09:47:34 +02:00

Task Watchdog Sample
####################

Overview
********

This sample allows to test the task watchdog subsystem.

Building and Running
********************

It should be possible to build and run the task watchdog sample on almost any
board. If a hardware watchdog is defined in the devicetree, it is used as a
fallback. Otherwise the task watchdog will run independently.

Building and Running for ST Nucleo L073RZ
=========================================
The sample can be built and executed for the
:ref:`nucleo_l073rz_board` as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/task_wdt
   :board: nucleo_l073rz
   :goals: build flash
   :compact:

For other boards just replace the board name.

Sample output
=============

The following output is printed and continuously repeated (after each
reset):

.. code-block:: console
