Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0 Move to CMake 3.20.0. At the Toolchain WG it was decided to move to CMake 3.20.0. The main reason for increasing CMake version is better toolchain support. Better toolchain support is added in the following CMake versions: - armclang, CMake 3.15 - Intel oneAPI, CMake 3.20 - IAR, CMake 3.15 and 3.20 Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>		2021-08-20 09:47:34 +02:00

IPC Service
###########

Overview
********

IPC Service is an abstraction layer.
It needs the corresponding backend registered for proper operation.
You can use any IPC mechanism as a backend.
In this sample, it is a multiple instance of RPMsg.
This sample demonstrates how to integrate IPC Service with Zephyr.

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

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

Open a serial terminal (for example Minicom or PuTTY) and connect the board with the
following settings:

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

When you reset the development kit, the following messages (one for master and one for remote) will appear on the corresponding serial ports:
