|
|
supported.
|
|
|
|
Connections and IOs
|
|
===================
|
|
|
|
The K66F SoC has five pairs of pinmux/gpio controllers.
|
|
|
|

|
|
|
|
System Clock
|
|
============
|
|
|
|
The K66F SoC is configured to use the 12 MHz low gain crystal oscillator on the
|
|
board with the on-chip PLL to generate a 180 MHz system clock.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
The K66F SoC has six UARTs. None of them are used.
|
|
|
|
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-jlink-onboard-debug-probe`.
|
|
|
|
: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.
|
|
|
|
The default flasher is ``jlink`` using the built-in SEGGER Jlink interface.
|
|
|
|
Flashing
|
|
========
|
|
|
|
Here is an example for the :ref:`blinky-sample` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: ip_k66f
|
|
:goals: flash
|
|
|
|
Red LED0 should blink at 1 second delay.
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Here is an example for the :ref:`blinky-sample` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: ip_k66f
|
|
:goals: debug
|
|
|
|
Step through the application in your debugger.

Serial console
|
|
==============
|
|
|
|
The ``ip_k66f`` board only uses Segger's RTT console for providing serial
|
|
console. There is no physical serial port available.
|
|
|
|
- To communicate with this board one needs in one console:
|
|
|
|
``/opt/SEGGER/JLink_V664/JLinkRTTLogger -Device MK66FN2M0XXX18 -RTTChannel 1 -if SWD -Speed 4000 ~/rtt.log``
|
|
|
|
- In another one:
|
|
|
|
``nc localhost 19021``
|
