The default configuration can be found in the defconfig file: boards/arm/npcx7m6fb_evb/npcx7m6fb_evb_defconfig

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

Build application as usual for the npcx7m6fb_evb board, and flash using Servo V2, μServo, or Servo V4 (CCD). See the Chromium EC Flashing Documentation 1 for more information.

Debugging

Use JTAG/SWD with a J-Link
