System Clock
============
The LPC55S16 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 LPC55S16 SoC has 8 FLEXCOMM interfaces for serial
communication. One is configured as USART for the console, one is
configured for I2C, 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 the LPC55S16 so you must reconfigure the board for one of the
J-Link debug probe instead.
First install the :ref:`jlink-debug-host-tools` and make sure they are
in your search path.
Then 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.
Configuring a Console
=====================
Connect a USB cable from your PC to J1 (LINK2), 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.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: lpcxpresso55s16
: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 v2.2.0 *****
Hello World! lpcxpresso55s16
Debugging
=========
Here is an example for the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: lpcxpresso55s16
: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-v2.2.0 *****
