.. zephyr:code-sample:: openamp
|
|
:name: OpenAMP
|
|
:relevant-api: ipm_interface
|
|
|
|
Send messages between two cores using OpenAMP.
|
|
|
|
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. Note that the remote and primary core images can be flashed
|
|
independently, but sysbuild must be used in order to build the images.

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:
