As hardware becomes increasingly complex with heterogeneous multi-core architectures, integrating rich OS environments like Linux with RTOS-based cores poses significant challenges. The OpenAMP framework, leveraging Remoteproc and RPMsg, facilitates communication between these diverse environments, but it still has some limitations.
This presentation will explore key challenges in using OpenAMP for multi-core systems and discuss solutions that have been proposed and implemented. Topics include address translation for shared memory and handling remote processor replies required by the host.
We will also dive into recent enhancements in both Linux and Zephyr that improve interoperability, ensuring seamless communication and synchronization between heterogeneous cores.
