Linux and Zephyr - Talking to Each Other in the Same SoC

Explore the integration of Linux and Zephyr operating systems on a single System-on-Chip (SoC) in this conference talk by Diego Sueiro. Discover how Hybrid Multiprocessor (HMP) architectures can leverage both operating systems to meet real-time constraints and implement specific features. Learn about the RPMsg protocol for inter-core communication and its implementation in both Linux and Zephyr. Gain insights into the initialization flow, necessary configurations, and a practical demonstration of Linux-Zephyr data sharing. Delve into topics such as real-time applications with HMP, RPMsg on Linux, and enabling RPMsg-lite on Zephyr. Benefit from Sueiro's extensive experience in embedded software development and his contributions to the Zephyr Project.
