History

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

Hello World
###########

Overview
========
A simple Hello World example that can be used with any supported board and
prints 'Hello World' to the console. This application can be built into modes:

* single thread
* multi threading

Building and Running
====================

This project outputs 'Hello World' to the console.  It can be built and executed
on QEMU as follows:

.. code-block:: console

   $ cd samples/hello_world
   $ make run


To build the single thread version, use the supplied configuration file for
single thread: :file:`prj_single.conf`:

.. code-block:: console

   $ make CONF_FILE=prj_single.conf run

Sample Output
-------------

.. code-block:: console

    Hello World! x86
