Daniel DeGrasse 41a63f48fd samples: task_wdt: Increase min watchdog timeout MCUX watchdog timer supports min window of 500ms. Increase maximum task watchdog timeout window to 500ms by default, so that this sample can run on iMX RT SOCs. Also update iMX RT watchdog driver to reject timeout maximums under 500ms with a useful error message Fixes #40153 Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>		2022-02-09 14:07:26 -06:00

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
