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 ======== 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/ .. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: npcx9m6f_evb :maybe-skip-config: :goals: build flash Debugging ========= Use JTAG/SWD with a J-Link References ********** .. target-notes:: .. _Chromium EC Flashing Documentation: https://chromium.googlesource.com/chromiumos/platform/ec#Flashing-via-the-servo-debug-board
