Overview
7+
********
8+
9+
The LPCXpresso54114 board has been developed by NXP to enable evaluation of and
10+
prototyping with the LPC54110 family of MCUs and with the low-power LPC54110
11+
family of MCUs. LPCXpresso* is a low-cost development platform available from
12+
NXP supporting NXP's ARM-based microcontrollers. LPCXpresso is an end-to-end
13+
solution enabling embedded engineers to develop their applications from initial
14+
evaluation to final production.

Supported Features
49+
==================
50+
51+
The lpcxpresso54114 board configuration supports the following hardware
52+
features:
53+
54+
+-----------+------------+-------------------------------------+
55+
| Interface | Controller | Driver/Component |
56+
+===========+============+=====================================+
57+
| NVIC | on-chip | nested vector interrupt controller |
58+
+-----------+------------+-------------------------------------+
59+
| SYSTICK | on-chip | systick |
60+
+-----------+------------+-------------------------------------+
61+
| IOCON | on-chip | pinmux |
62+
+-----------+------------+-------------------------------------+
63+
| GPIO | on-chip | gpio |
64+
+-----------+------------+-------------------------------------+
65+
| USART | on-chip | serial port-polling |
66+
+-----------+------------+-------------------------------------+
67+
68+
The default configuration can be found in the defconfig file:
69+
70+
``boards/arm/lpcxpresso54114/lpcxpresso54114_defconfig``
71+
72+
Other hardware features are not currently supported by the port.
73+
74+
Connections and IOs
75+
===================
76+
77+
The LPC54114 SoC has IOCON registers, which can be used to configure the
78+
functionality of a pin.

System Clock
95+
============
96+
97+
The LPC54114 SoC is configured to use the internal FRO at 48MHz as a source for
98+
the system clock. Other sources for the system clock are provided in the SOC,
99+
depending on your system requirements.
100+
101+
Serial Port
102+
===========
103+
104+
The LPC54114 SoC has 8 FLEXCOMM interfaces for serial communication. One is
105+
configured as USART for the console and the remaining are not used.
106+
107+
Programming and Debugging
108+
*************************
109+
110+
The LPCXpresso54114 includes the LPC-Link2 serial and debug adapter built into
111+
the board to provide debugging, flash programming, and serial communication
112+
over USB. LPC-Link2 can be configured with Segger J-Link or CMSIS-DAP firmware
113+
variants to support corresponding debug tools. Currently only the Segger J-Link
114+
tools are supported for this board in Zephyr, therefore you should use the
115+
Segger J-Link firmware variant.
116+
117+
Before you start using Zephyr on the LPCXpresso54114, download and run
118+
`LPCScrypt`_ to update the LPC-Link2 firmware to the latest version, currently
119+
``Firmware_JLink_LPC-Link2_20160923.bin``. Serial communication problems, such
120+
as dropping characters, have been observed with older versions of the firmware.
121+
122+
Debugging
123+
=========
124+
125+
You can debug an application in the usual way. Here is an example for the
126+
:ref:`hello_world` application.
127+
128+
.. zephyr-app-commands::
129+
:zephyr-app: samples/hello_world
130+
:board: lpcxpresso54114
131+
:goals: debug
132+
133+
Open a serial terminal (minicom, putty, etc.) and connect the board with the
134+
following settings:
135+
136+
- Speed: 115200
137+
- Data: 8 bits
138+
- Parity: None
139+
- Stop bits: 1
140+
141+
Reset the board and the following message will appear on the corresponding
142+
serial port:
143+
144+
.. code-block:: console
