Hardware

ARM Cortex-M4F Processor
256 KB RAM and 64 KB boot ROM
ADC & GPIO headers
UART0 and UART1
FAN PWM interface
Jtag interface
Intel Modular Embedded Controller Card (MECC) headers

Supported Features

.. zephyr:board-supported-hw::

Connections and IOs

Nuvoton to provide the schematic for this board.

System Clock

The NPCX9M6F MCU is configured to use the 90Mhz internal oscillator with the on-chip PLL to generate a resulting EC clock rate of 15 MHz. See Processor clock control register (chapter 4 in user manual)

Serial Port

UART1 is configured for serial logs.

Programming and Debugging

.. zephyr:board-supported-runners::

This board comes with a Cortex ETM port which facilitates tracing and debugging using a single physical connection. In addition, it comes with sockets for JTAG-only sessions.

Flashing

If the correct IDC headers are installed, this board supports both J-TAG and also the ChromiumOS servo.

To flash using Servo V2, μServo, or Servo V4 (CCD), see the Chromium EC Flashing Documentation_ for more information.

To flash with J-TAG, install the drivers for your programmer, for example: SEGGER J-link's drivers are at https://www.segger.com/downloads/jlink/

Debugging

Use JTAG/SWD with a J-Link
