This repository contains a Zephyr example application. The main purpose of this repository is to serve as a reference on how to structure Zephyr-based applications. Some of the features demonstrated in this example are:
- Basic Zephyr application skeleton
- Zephyr workspace applications
- Zephyr modules
- West T2 topology
- Custom boards
- Custom devicetree bindings
- Out-of-tree drivers
- Out-of-tree libraries
- Example CI configuration (using Github Actions)
- Custom west extension
This repository is versioned together with the Zephyr main tree. This
means that every time that Zephyr is tagged, this repository is tagged as well
with the same version number, and the manifest entry for zephyr
will point to the corresponding Zephyr tag. For example, the example-application
v2.6.0 will point to Zephyr v2.6.0. Note that the main branch always
points to the development branch of Zephyr, also main.
Before getting started, make sure you have a proper Zephyr development environment. Follow the official Zephyr Getting Started Guide.
The first step is to initialize the workspace folder (my-workspace) where
the example-application and all Zephyr modules will be cloned. Run the following
command:
# initialize my-workspace for the example-application (main branch)
west init -m https://github.com/zephyrproject-rtos/example-application --mr main my-workspace
# update Zephyr modules
cd my-workspace
west updateTo build the application, run the following command:
west build -b $BOARD appwhere $BOARD is the target board.
You can use the custom_plank board found in this
repository. Note that Zephyr sample boards may be used if an
appropriate overlay is provided (see app/boards).
A sample debug configuration is also provided. To apply it, run the following command:
west build -b $BOARD app -- -DOVERLAY_CONFIG=debug.confOnce you have built the application, run the following command to flash it:
west flashTo execute Twister integration tests, run the following command:
west twister -T tests --integration
