+
+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
+*************************
+
+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 :ref:`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
