Overview
********

The RDDRONE FMUK66 is an drone control board with commonly used peripheral
connectors and a Kinetis K66 on board.

- Comes with a J-Link Edu Mini for programming and UART console.

Supported Features
==================

.. zephyr:board-supported-hw::

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

The K66F SoC is configured to use the 16 MHz external oscillator on the board
with the on-chip PLL to generate a 160 MHz system clock.

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

The K66F SoC has six UARTs. LPUART0 is configured for the console, UART0 is labeled Serial 2,
UART2 is labeled GPS, UART4 is labeled Serial 1. Any of these UARTs may be used as the console by
overlaying the board device tree.

USB
===

The K66F SoC has a USB OTG (USBOTG) controller that supports both
device and host functions through its micro USB connector (K66F USB).
Only USB device function is supported in Zephyr at the moment.

Programming and Debugging
*************************

.. zephyr:board-supported-runners::

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 jlink. The board package
with accessories comes with a jlink mini edu and cable specifically for this board
along with a usb to uart that connects directly to the jlink mini edu. This is the expected
default configuration for programming and getting a console.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: rddrone-fmuk66
   :gen-args:
   :goals: build

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

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 :zephyr:code-sample:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: rddrone-fmuk66
   :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 v2.7.0 *****
   Hello World! rddrone-fmuk66

Debugging
=========

Here is an example for the :zephyr:code-sample:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: rddrone-fmuk66
   :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 v2.7.0 *****
   Hello World! rddrone-fmuk66
