Connections and IOs
Nuvoton to provide the schematic for this board.
System Clock
The NPCX7M6FB 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
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 [1] 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/
