Yocto/Openembedded

yocto and OpenEmbedded provide the tools necessary to create small customised linux distributions aimed at embedded systems.

Learn about Yocto and bitbake which uses recipes structured in various layers to build custom images, see Introduction to Yocto/OpenEmbedded.

Read about Layers and Recipes therein.

Use devtool to add, modify and test new recipes.

For setting up the build environment, see Setup and Building.

Getting Started with Yocto and C/C++ demonstrates how the build environment is setup, a x86-64 image is built and run on Qemu. Then a C++ application is added to this image.

There are essentially four ways to build on/for a yocto image:

• Creating a recipe for the application and adding it to the image, see Getting Started with Yocto and C/C++. This method includes a full build of the image.
• Crosscompile with a cross development SDK, see SDK.
• Use the extensible SDK. With this, you use the regular yocto workflow without the need of building a complete image first, see SDK's.
• Include the toolchain in the image and build natively (not recommended), see SDK's.

• meta-ost is the layer containing recipes required for various OST projects.
• meta-ost-ethercat is the layer containing recipes for EtherCAT support.

Prebuilt images for our supported platforms together with SDK and extended SDK are available at Linux Images.

Learn about how our layers are structured, about how our CI/CD pipeline works and about how you could commit to the project in Structure / Workflow.

Work is under way to include ROS in our builds.
