********
|
|
|
|
The Freedom-K64F is an ultra-low-cost development platform for Kinetis K64,
|
|
K63, and K24 MCUs.
|
|
|
|
- Form-factor compatible with the Arduino R3 pin layout
|
|
- Peripherals enable rapid prototyping, including a 6-axis digital
|
|
accelerometer and magnetometer to create full eCompass capabilities, a
|
|
tri-colored LED and 2 user push-buttons for direct interaction, a microSD
|
|
card slot, and connectivity using onboard Ethernet port and headers for use
|
|
with Bluetooth* and 2.4 GHz radio add-on modules
|
|
- OpenSDAv2, the NXP open source hardware embedded serial and debug adapter
|
|
running an open source bootloader, offers options for serial communication,
|
|

Do not enable Ethernet and UART BT HCI simultaneously because they conflict
|
|
on PTC16-17.
|
|
|
|
System Clock
|
|
============
|
|
|
|
The K64F SoC is configured to use the 50 MHz external oscillator on the board
|
|
with the on-chip PLL to generate a 120 MHz system clock.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
The K64F SoC has six UARTs. One is configured for the console, another for BT
|
|
HCI, and the remaining are not used.
|
|
|
|
USB
|
|
===
|
|
|
|
The K64F SoC has a USB OTG (USBOTG) controller that supports both
|
|
device and host functions through its micro USB connector (K64F USB).
|
|
Only USB device function is supported in Zephyr at the moment.
|
|
|
|
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`.
|
|
|
|
Early versions of this board have an outdated version of the OpenSDA bootloader
|
|
and require an update. Please see the `DAPLink Bootloader Update`_ page for
|
|
instructions to update from the CMSIS-DAP bootloader to the DAPLink bootloader.
|
|
|
|
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-K64F 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 Generic Firmware for V3.2 Bootloader`_. Note that Segger
|
|
does provide an OpenSDA J-Link Board-Specific Firmware for this board, however
|
|
it is not compatible with the DAPLink bootloader.
|
|
|
|
Add the argument ``-DOPENSDA_FW=jlink`` when you invoke ``cmake`` or ``west
|
|
build`` to override the default runner from pyOCD to J-Link:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: frdm_k64f
|
|
: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 J26.
|
|
|
|
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_k64f
|
|
: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_k64f
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: frdm_k64f
|
|
: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 *****
|
|
