:name: IPM on NXP LPC
:relevant-api: ipm_interface
Implement inter-processor mailbox (IPM) on NXP LPC family.
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

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:
