Overview
|
|
********
|
|
|
|
The LPCXpresso54114 board has been developed by NXP to enable evaluation of and
|
|
prototyping with the low-power LPC54110 family of MCUs. LPCXpresso* is a
|
|
low-cost development platform available from NXP supporting NXP's ARM-based
|
|
microcontrollers. LPCXpresso is an end-to-end solution enabling embedded
|
|
engineers to develop their applications from initial evaluation to final
|
|
production.

System Clock
|
|
============
|
|
|
|
The LPC54114 SoC is configured to use the internal FRO at 48MHz 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 LPC54114 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` do not 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.
|
|
|
|
Configuring a Console
|
|
=====================
|
|
|
|
Regardless of your choice in debug probe, we will use the LPC-Link2
|
|
microcontroller as a usb-to-serial adapter for the serial console.
|
|
|
|
Connect a USB cable from your PC to J5
|
|
|
|
Use the following settings with your serial terminal of choice (minicom, putty,
|
|
etc.):
|
|
|
|
- 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: lpcxpresso54114_m4
|
|
:goals: flash
|
|
|
|
Open a serial terminal, reset the board (press the SW4 button), and you should
|
|
see the following message in the terminal:
|
|
|
|
.. code-block:: console
|
|
|
|
***** Booting Zephyr OS v1.14.0-rc1 *****
|
|
Hello World! lpcxpresso54114_m4
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: lpcxpresso54114_m4
|
|
: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 v1.14.0-rc1 *****
