NXP LPCXPRESSO55S69
###################

Overview
********

The LPCXpresso55S69 development board provides the ideal platform for evaluation
of and development with the LPC55S6x MCU based on the Arm® Cortex®-M33
architecture. The board includes a high performance onboard debug probe, audio
subsystem, and accelerometer, with several options for adding off-the-shelf
add-on boards for networking, sensors, displays, and other interfaces.

- `LPCXPRESSO55S69 User Guide`_
- `LPCXPRESSO55S69 Schematics`_

Supported Features
==================

The lpcxpresso55s69 board configuration supports the following hardware
features:

+-----------+------------+-------------------------------------+
| Interface | Controller | Driver/Component |
+===========+============+=====================================+
| NVIC | on-chip | nested vector interrupt controller |
+-----------+------------+-------------------------------------+
| SYSTICK | on-chip | systick |
+-----------+------------+-------------------------------------+
| IOCON | on-chip | pinmux |
+-----------+------------+-------------------------------------+
| GPIO | on-chip | gpio |
+-----------+------------+-------------------------------------+
| USART | on-chip | serial port-polling |
+-----------+------------+-------------------------------------+

The default configuration file
``boards/arm/lpcxpresso55s69/lpcxpresso55s69_cpu0_defconfig``
only enables the first core.

Other hardware features are not currently supported by the port.

Connections and IOs
===================

The LPC55S69 SoC has IOCON registers, which can be used to configure the
functionality of a pin.

+---------+-----------------+----------------------------+
| Name | Function | Usage |
+=========+=================+============================+
| PIO0_29 | USART | USART RX |
+---------+-----------------+----------------------------+
| PIO0_30 | USART | USART TX |
+---------+-----------------+----------------------------+
| PIO1_4 | GPIO | RED LED |
+---------+-----------------+----------------------------+
| PIO1_6 | GPIO | BLUE_LED |
+---------+-----------------+----------------------------+
| PIO1_7 | GPIO | GREEN LED |
+---------+-----------------+----------------------------+

System Clock
============

The LPC55S69 SoC is configured to use the internal FRO at 96MHz as a source for
the system clock. Other sources for the system clock are provided in the SOC,
depending on your system requirements.

Serial Port
===========

The LPC55S69 SoC has 8 FLEXCOMM interfaces for serial communication. One is
configured as USART for the console and the remaining are not used.

Programming and Debugging
*************************

Build and flash applications as usual (see :ref:`build_an_application` and
:ref:`application_run` for more details).

Configuring a Debug Probe
=========================

A debug probe is used for both flashing and debugging the board. This board is
configured by default to use the LPC-Link2 CMSIS-DAP Onboard Debug Probe,
however the :ref:`pyocd-debug-host-tools` does not yet support this probe so you
must reconfigure the board for one of the following debug probes instead.

:ref:`lpclink2-jlink-onboard-debug-probe`
-----------------------------------------

Install the :ref:`jlink-debug-host-tools` and make sure they are in your search
path.

Follow the instructions in :ref:`lpclink2-jlink-onboard-debug-probe` to program
the J-Link firmware. Please make sure you have the latest firmware for this
board.

:ref:`opensda-daplink-onboard-debug-probe`
------------------------------------------

PyOCD support for this board is ongoing and not yet available.
To use DAPLink's flash memory programming on this board, follow the instructions
for `updating LPCXpresso firmware`_.

Configuring a Console
=====================

Connect a USB cable from your PC to P6, and use the serial terminal of your choice
(minicom, putty, etc.) with the following settings:

- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1

Flashing
========

Here is an example for the :ref:`hello_world` application. This example uses the
:ref:`jlink-debug-host-tools` as default.

.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: lpcxpresso55s69_cpu0
:goals: flash

Open a serial terminal, reset the board (press the RESET button), and you should
see the following message in the terminal:

.. code-block:: console

***** Booting Zephyr OS v1.14.0 *****
Hello World! lpcxpresso55s69_cpu0

Debugging
=========

Here is an example for the :ref:`hello_world` application. This example uses the
:ref:`jlink-debug-host-tools` as default.

.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: lpcxpresso55s69_cpu0
:goals: debug

Open a serial terminal, step through the application in your debugger, and you
should see the following message in the terminal:

.. code-block:: console

***** Booting Zephyr OS zephyr-v1.14.0 *****
Hello World! lpcxpresso55s69_cpu0
