Supported Features

.. zephyr:board-supported-hw::

Micrel/Microchip KSZ8794CNX Ethernet Switch is supported (see :zephyr:code-sample:dsa sample).

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

.. 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 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.
