Open Source Summit Europe 2024

The Zephyr build system had been reaching its limits in its ability to build multiple images for modern SoCs in its previous hardware model.
The original build system began with the concept of a simple board containing a single core SoC for which you would build a single image. In today's world however, developers want to build multiple images for boards which may have multiple SoCs and / or SoCs with multiple CPU cores. This evolution towards complexity led us to the development and introduction of sysbuild and a new hardware model in Zephyr.

The purpose of this talk is to dive into the new hardware model, and what it provides seen from a developer's point of view, and from there continue into sysbuild, where the new hardware model is leveraged in order to build multiple images for a single device. The talk will go over how you as a developer can make the best use of the new hardware model and sysbuild to effectively build a complete project.
