Zephyr project is provided as source code and build scripts for different target architectures and configurations, and not as a binary image. (See Supported Boards documentation for details.) Updated versions of the Zephyr project are released approximately every three-months. (See Release Roadmap for details.)
All Zephyr project source code is maintained in a Git repository; you can either download source as a tar.gz file (see the bottom of the GitHub release notes pages listed below), or use Git clone and checkout commands, such as:
git clone https://github.com/zephyrproject-rtos/zephyr cd zephyr git checkout tags/v1.8.0
The tools used to build an image are available as a Software Development Kit (SDK) in the Zephyr SDK Tools section below.
- The project’s technical documentation is also tagged to correspond with a specific release and can be found at https://www.zephyrproject.org/doc/.
