 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.

 Connections and IOs
 ===================

 The KW41Z SoC has three pairs of pinmux/gpio controllers, but only two are
 currently enabled (PORTA/GPIOA and PORTC/GPIOC) for the FRDM-KW41Z board.

 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
 *************************

 Flashing
 ========

 The FRDM-KW41Z includes an `OpenSDA`_ serial and debug adaptor built into the
 board. The adaptor provides:

 - A USB connection to the host computer, which exposes a Mass Storage and an
   USB Serial Port.
 - A Serial Flash device, which implements the USB flash disk file storage.
 - A physical UART connection which is relayed over interface USB Serial port.

 Flashing an application to FRDM-KW41Z
 -------------------------------------

 The sample application :ref:`hello_world` is used for this example.
 Build the Zephyr kernel and application:

 .. code-block:: console

    $ cd $ZEPHYR_BASE
    $ . zephyr-env.sh
    $ cd $ZEPHYR_BASE/samples/hello_world/
    $ make BOARD=frdm_kw41z

 Connect the FRDM-KW41Z to your host computer using the USB port and you should
 see a USB connection which exposes a Mass Storage (DAPLINK) and a USB Serial
 Port. Copy the generated zephyr.bin in the DAPLINK drive.

 Reset the board and you should be able to see on the corresponding Serial Port
 the following message:

 .. code-block:: console

    Hello World! arm
