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¶
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 npcx9m6f_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
