| 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 |
| |
