Micrel/Microchip KSZ8794CNX Ethernet Switch is supported (see DSA (Distributed Switch Architecture) sample).

Connections and IOs

The K66F SoC has five pairs of pinmux/gpio controllers.

Name	Function	Usage
PTA8	GPIO	Red LED
PTA10	GPIO	RED LED

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

The ip_k66f board supports the runners and associated west commands listed below.

	flash	debug	attach	debugserver	rtt
jlink	✅ (default)	✅ (default)	✅	✅	✅
openocd	✅	✅	✅	✅	✅
pyocd	✅	✅	✅	✅	✅

Build and flash applications as usual (see Building an Application and Run an Application 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 OpenSDA J-Link Onboard Debug Probe.

OpenSDA J-Link Onboard Debug Probe

Install the J-Link Debug Host Tools and make sure they are in your search path.

Follow the instructions in OpenSDA J-Link 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 Blinky application.

# From the root of the zephyr repository
west build -b ip_k66f samples/basic/blinky
west flash

Red LED0 should blink at 1 second delay.

Debugging

Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b ip_k66f samples/basic/blinky
west 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
