: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:
|
|
- :zephyr:board:`lpcxpresso54114`, two core processors (Cortex-M4F and Cortex-M0+)
|
|
- :zephyr:board:`lpcxpresso55s69`, two core processors (dual Cortex-M33)
|
|
|
|
Requirements

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:
|
|
|
|
.. code-block:: console
