10This application demonstrates how to use OpenAMP with Zephyr. It is designed to
11demonstrate how to integrate OpenAMP with Zephyr both from a build perspective
12and code. Note that the remote and primary core images can be flashed
13independently, but sysbuild must be used in order to build the images.
