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
Debugging
Use JTAG/SWD with a J-Link
