Overview
4+
********
5+
6+
The FRDM-KE16Z is a development board for NXP Kinetis KE1xZ 32-bit
7+
MCU-based platforms. The FRDM-KE16Z contains a robust TSI module
8+
with up to 25 channels which makes this board highly flexible
9+
for touch keys. Offers options for serial
10+
communication, flash programming, and run-control debugging.
11+
12+
Hardware
13+
********
14+
15+
- MKE16Z64VLF4 MCU (up to 48 MHz, 64 KB flash memory, 8 KB RAM)
16+
- OpenSDA Debug Circuit with a virtual serial port
17+
- Touch electrodes in the self-capacitive mode
18+
- Compatible with FRDM-TOUCH, FRDM-MC-LVBLDC, and Arduino® boards
19+
- User Components such as Reset; RGB LED and two user buttons
20+
- 6-axis FXOS8700CQ digital accelerometer and magnetometer
21+
22+

Supported Features
33+
==================
34+
35+
.. zephyr:board-supported-hw::
36+
37+
System Clock
38+
============
39+
40+
The KE16 SoC is configured to run at 48 MHz using the FIRC.
41+
42+
Serial Port
43+
===========
44+
45+
The KE16 SoC has three UARTs. UART0 (PTB1, PTB0) is configured for the console.
46+
47+
Programming and Debugging
48+
*************************
49+
50+
.. zephyr:board-supported-runners::
51+
52+
Build and flash applications as usual (see :ref:`build_an_application` and
53+
:ref:`application_run` for more details).
54+
55+
Configuring a Debug Probe
56+
=========================
57+
58+
A debug probe is used for both flashing and debugging the board. This board is
59+
configured by default to use Linkserver.
60+
61+
Early versions of this board have an outdated version of the OpenSDA bootloader
62+
and require an update. Please see the `DAPLink Bootloader Update`_ page for
63+
instructions to update from the CMSIS-DAP bootloader to the DAPLink bootloader.
64+
65+
Option 1: Linkserver
66+
-------------------------------------------------------
67+
68+
Install the :ref:`linkserver-debug-host-tools` and make sure they are in your
69+
search path. LinkServer works with the default CMSIS-DAP firmware included in
70+
the on-board debugger.
71+
72+
Linkserver is the default for this board, ``west flash`` and ``west debug`` will
73+
call the linkserver runner.
74+
75+
Option 2: :ref:`opensda-jlink-onboard-debug-probe`
76+
--------------------------------------------------
77+
78+
Install the :ref:`jlink-debug-host-tools` and make sure they are in your search
79+
path.
80+
81+
82+
Use the ``-r jlink`` option with west to use the jlink runner.
83+
84+
.. code-block:: console
85+
86+
west flash -r jlink
87+
88+
Configuring a Console
89+
=====================
90+
91+
Regardless of your choice in debug probe, we will use the OpenSDA
92+
microcontroller as a usb-to-serial adapter for the serial console.
93+
94+
Connect a USB cable from your PC to J6.
95+
96+
Use the following settings with your serial terminal of choice (minicom, putty,
97+
etc.):
98+
99+
- Speed: 115200
100+
- Data: 8 bits
101+
- Parity: None
102+
- Stop bits: 1
103+
104+
Flashing
105+
========
106+
107+
Here is an example for the :zephyr:code-sample:`hello_world` application.
108+
109+
.. zephyr-app-commands::
110+
:zephyr-app: samples/hello_world
111+
:board: frdm_ke16z
112+
:goals: flash
113+
114+
Open a serial terminal, reset the board (press the SW1 button), and you should
115+
see the following message in the terminal:
116+
117+
.. code-block:: console
118+
119+
*** Booting Zephyr OS build v3.6.0-3478-gb923667860b1 ***
120+
Hello World! frdm_ke16z/mke16z4
121+
122+
Debugging
123+
=========
124+
125+
Here is an example for the :zephyr:code-sample:`hello_world` application.
126+
127+
.. zephyr-app-commands::
128+
:zephyr-app: samples/hello_world
129+
:board: frdm_ke16z
130+
:goals: debug
131+
132+
Open a serial terminal, step through the application in your debugger, and you
133+
should see the following message in the terminal:
134+
135+
.. code-block:: console
136+
137+
