Embedded Open Source Summit 2023

Looking at system architectures for complex embedded systems, similarities can be observed across various industries. Beside a rich OS (such as Linux), often an RTOS and virtualization or containers are involved. However, when it comes to prototyping such systems, the existing guidelines are limited and reproducing demos is hard and time consuming. The ELISA project’s systems working group focuses on creating an exemplary system architecture using Linux (like from AGL, CIP or APERTIS), Xen and Zephyr in a reproducible form. This includes step-by-step documentation for users on different expert levels and various entry points to approach these systems. The results of this activity are presented and shared as part of the talk. Additionally, an outlook to further work is provided, which includes picking up new requirements such as a system SBOM. The demand for strong interaction and collaboration among various open source projects will also be shortly addressed in this talk. Finally, the talk gets rounded up by showcasing the system implementation state. The demonstrated example is based on embedded automotive hardware and facilitates the usage of the AGL reference stack along with Xen and Zephyr.
