Connections and IOs

Nuvoton to provide the schematic for this board.

Serial Port

UART0 is configured for serial logs. The default serial setup is 115200 8N1.

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 headers are installed, this board supports J-TAG.

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/

Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: npcm400_evb :goals: flash

Open a serial terminal, and you should see the following message in the terminal:

.. code-block:: console

Hello World! npcm400_evb/npcm400

Debugging

Use JTAG/SWD with a J-Link
