:name: IPC service: static vrings backend
|
|
:relevant-api: ipc
|
|
|
|
Send messages between two cores using the IPC service and 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:
