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 Hello World application.

# From the root of the zephyr repository
west build -b npcm400_evb samples/hello_world
west flash

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

Hello World! npcm400_evb/npcm400
