IPC service: static vrings backend

Overview

This application demonstrates how to use IPC Service and the static vrings backend with Zephyr. It is designed to demonstrate how to integrate it 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 host another is remote:
