SEGGER IP Switch Board

Overview

The Segger IP Switch Board is a Evaluation board based on NXP Kinetis K66 MCU. It comes with Micrel/Microchip KSZ8794CNX integrated 4-port 10/100 managed Ethernet switch with Gigabit RGMII/MII/RMII interface.

  • KSZ8794CNX enables evaluation for switch functions

  • On-board debug probe J-Link-OB for programming

IP-K66F

Hardware

  • MK66FN2M0VMD18 MCU (180 MHz, 2 MB flash memory, 256 KB RAM, low-power, crystal-less USB

  • Dual role USB interface with micro-B USB connector

  • 2 User LED

  • On-board debug probe J-Link-OB for programming

  • Micrel/Microchip Ethernet Switch KSZ8794CNX with 3 RJ45 connectors

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 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.

Flashing

Here is an example for the Blinky sample 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 sample 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.
