Overview

The EVK-NINA-B5 is a compact and scalable development board for rapid prototyping of the NINA-B5 wireless module. It offers easy evaluation of the NINA-B5's multiprotocol wireless support for Bluetooth LE, Zigbee, Thread and Matter. The board includes an on-board J-link-Link debugger and industry standard headers for easy access to the MCU’s I/Os.

The NINA-B5 module is built on the MCX W71x 96 MHz Arm® Cortex®-M33 from NXP.

Hardware

  • MCXW71 Arm Cortex-M33 microcontroller running up to 96 MHz
  • 1MB on-chip Flash memory unit
  • 128 KB TCM RAM
  • On-board MCU-Link debugger with CMSIS-DAP

For more information about the NINA-B5 module and EVK-NINA-B5 board, see:

Supported Features

.. zephyr:board-supported-hw::

Fetch Binary Blobs

To support Bluetooth, ubx_evkninab5 requires fetching binary blobs, which can be achieved by running the following command:

.. code-block:: console

west blobs fetch hal_nxp

Note: The EVK-NINA-B5 is preflashed with NBU files.

Programming and Debugging

.. zephyr:board-supported-runners::

Build and flash applications as usual (see :ref:build_an_application and :ref:application_run for more details).

Configuring a Debug Probe

A debug probe is used for both flashing and debugging the board. This board is configured by default to use the MCU-Link CMSIS-DAP Onboard Debug Probe.

The onboard debug circuit is a Segger J-Link debugger

The second option is to attach a :ref:jlink-external-debug-probe to the 10-pin SWD connector (J12) of the board.

For both options use the -r jlink option with west to use the jlink runner.

.. code-block:: console

west flash -r jlink

Configuring a Console

Connect a USB cable from your PC to the USB port, and use the serial terminal of your choice (minicom, putty, etc.) with the following settings:

  • Speed: 115200
  • Data: 8 bits
  • Parity: None
  • Stop bits: 1

Application Building

.. zephyr-app-commands:: :zephyr-app: samples/basic/button :board: ubx_evkninab5 :goals: build :gen-args:

Application Flashing

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

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: ubx_evkninab5 :goals: flash

Open a serial terminal, reset the board (press the RESET button), and you should see the following message in the terminal:

.. code-block:: console

*** Booting Zephyr OS build v3.7.0-xxx-xxxx *** Hello World! ubx_evkninab5

Debugging

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

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: ubx_evkninab5 :goals: debug

Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:

.. code-block:: console

*** Booting Zephyr OS build v3.7.0-xxx-xxxx *** Hello World! ubx_evkninab5

NBU Flashing

BLE functionality requires to fetch binary blobs, so make sure to follow the Fetch Binary Blobs section first.

Two images must be written to the board: one for the host (CM33) and one for the NBU (CM3).

  • To flash the application (CM33) refer to the Application Flashing section above.

  • To flash the NBU Flashing, follow the instructions below in the NINA-B5 system integration manual available on the NINA-B5 product page_.

The NBU files can be found in : <zephyr workspace>/modules/hal/nxp/zephyr/blobs/mcxw71/ folder.
