 NXP FRDM-KW41Z
 ##############

 Overview
 ********

 The FRDM-KW41Z is a development kit enabled by the Kinetis |reg| W series
 KW41Z/31Z/21Z (KW41Z) family built on ARM |reg| Cortex |reg|-M0+ processor with
 integrated 2.4 GHz transceiver supporting Bluetooth |reg| Smart/Bluetooth
 |reg| Low Energy
 (BLE) v4.2, Generic FSK, IEEE |reg| 802.15.4 and Thread.

 The FRDM-KW41Z kit contains two Freedom boards that can be used as a
 development board or a shield to connect to a host processor. The FRDM-KW41Z is
 form-factor compatible with the Arduino |trade| R3 pin layout for more expansion
 options.

 The FRDM-KW41Z highly-sensitive, optimized 2.4 GHz radio features a PCB
 F-antenna which can be bypassed to test via SMA connection, multiple power
 supply options, push/capacitive touch buttons, switches, LEDs and integrated
 sensors.

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

 The KW41Z SoC is configured to use the 32 MHz external oscillator on the board
 with the on-chip FLL to generate a 40 MHz system clock.

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

 The KW41Z SoC has one UART, which is used for the console.

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

 Option 1: :ref:`opensda-daplink-onboard-debug-probe` (Recommended)
 ------------------------------------------------------------------

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

 Follow the instructions in :ref:`opensda-daplink-onboard-debug-probe` to program
 the `OpenSDA DAPLink FRDM-KW41Z Firmware`_.

 Option 2: :ref:`opensda-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:`opensda-jlink-onboard-debug-probe` to program
 the `OpenSDA J-Link FRDM-KW41Z Firmware`_.

 Add the argument ``-DOPENSDA_FW=jlink`` when you invoke ``west build`` to
 override the default runner from pyOCD to J-Link:

 .. zephyr-app-commands::
    :zephyr-app: samples/hello_world
    :board: frdm_kw41z
    :gen-args: -DOPENSDA_FW=jlink
    :goals: build

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

 Regardless of your choice in debug probe, we will use the OpenSDA
 microcontroller as a usb-to-serial adapter for the serial console.

 Connect a USB cable from your PC to J6.

 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: frdm_kw41z
    :goals: flash

 Open a serial terminal, reset the board (press the SW1 button), and you should
 see the following message in the terminal:

 .. code-block:: console

    ***** Booting Zephyr OS v1.14.0-rc1 *****
    Hello World! frdm_kw41z

 Debugging
 =========

 Here is an example for the :ref:`hello_world` application.

 .. zephyr-app-commands::
    :zephyr-app: samples/hello_world
    :board: frdm_kw41z
    :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 *****
    Hello World! frdm_kw41z
