Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

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

Overview
********

The :ref:`lpcxpresso54114` board has two core processors (Cortex-M4F
and Cortex-M0+). This sample application uses a mailbox to send messages
from one processor core to the other.

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

- :ref:`lpcxpresso54114` board

Building and Running
********************

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/ipc/ipm_mcux
   :board: lpcxpresso54114_m4
   :goals: debug

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:
