RPMsg Service sample Application
################################
Overview
********
RPMsg Service is an abstraction created over OpenAMP that makes initialization
and endpoints creation process easier.
This application demonstrates how to use RPMsg Service in Zephyr. It is designed
to demonstrate how to integrate RPMsg Service 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:
.. code-block:: console

Building the application for bl5340_dvk_cpuapp
**********************************************

Open a serial terminal (for example Minicom or PuTTY) and connect to the board
with the following settings on both serial ports:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
When you reset the development kit after having flashed both the application
and network core images, the following messages (one for master and one for
remote) will appear on the corresponding serial ports:
.. code-block:: console
