OpenAMP Sample Application

Overview

This application demonstrates how to use OpenAMP with Zephyr. It is designed to demonstrate how to integrate OpenAMP with Zephyr both from a build perspective and code.

Open a serial terminal (minicom, putty, etc.) and connect the board with the following settings:

  • Speed: 115200

  • Data: 8 bits

  • Parity: None

  • Stop bits: 1

Reset the board and the following message will appear on the corresponding serial port, one is master another is remote:
