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

Multiple instance of RPMsg
##########################

Overview
********

Multiple instance of RPMsg is an abstraction created over OpenAMP.
It simplifies the initialization and endpoint creation process.
This sample demonstrates how to use multi-instance RPMsg in Zephyr.

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

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/rpmsg_multi_instance
   :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:
