OpenAMP performance Sample Application
######################################

Overview
********

This application demonstrates how to measure OpenAMP performance / throughput
with Zephyr.

Building the application for nrf5340dk_nrf5340_cpuapp
*****************************************************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/openamp_performance
   :board: nrf5340dk_nrf5340_cpuapp
   :goals: debug

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:
