Run an Application
|
|
##################
|
|
|
|
An appliction image can be run on real or simulated hardware.
|
|
The kernel's built-in simulator is QEMU. It allows you to run and test
|
|
an application virtually, before (or in lieu of)
|
|
loading and running it on actual target hardware.

Running an Application using QEMU
|
|
=================================
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
* Ensure the application can be built successfully using a QEMU-supported
|
|
board configuration, such as qemu_cortex_m3 or qemu_x86, as described
|
|
in :ref:`apps_build`.
|
|
|
|
* Ensure the Zephyr environment variables are set for each console terminal;
|
|
see :ref:`apps_common_procedures`.
|
|
|
|
Steps
|
|
-----
|
|
|
|
#. Open a terminal console and navigate to the application directory
|
|
:file:`~/appDir`.
|
|
|
|
#. Enter the following command to build and run the application
|
|
using a QEMU-supported board configuration,
|
|
such as qemu_cortex_m3 or qemu_x86.
|
|
|
|
.. code-block:: console
|
|
|
|
$ make [BOARD=<type> ...] qemu
|
|
|
|
The Zephyr build system generates a :file:`zephyr.elf` image file
|
|
and then begins running it in the terminal console.
|
|
|
|
#. Press :kbd:`Ctrl A, X` to stop the application from running
|
|
in QEMU.
|
|
|
|
The application stops running and the terminal console prompt
|
|
redisplays.
|
|
|
|
Loading and Running an Application on Target Hardware
|
|
=====================================================
|
|
|
|
The procedure required to load an application image (:file:`zephyr.elf`)
|
|
on a target depends on the functionality available on its hardware,
|
|
and is often unique to that target board.
|
|
For this reason, loading instructions reside with the board-specific
|
|
documentation; see :ref:`board`.
