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

Sample mailbox application
##########################

Overview
********

Some NXP microcontrollers from LPC family are dual-core, this
sample application uses a mailbox to send messages from one
processor core to the other.

This sample applies to the following boards:
 -  :ref:`lpcxpresso54114`, two core processors (Cortex-M4F and Cortex-M0+)
 -  :ref:`lpcxpresso55s69`, two core processors (dual Cortex-M33)

Requirements
************

- :ref:`lpcxpresso54114` board
- :ref:`lpcxpresso55s69` board

Building the application for lpcxpresso54114_m4

Running
*******
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:
