.. zephyr:board:: nucleo_f439zi

Overview

The Nucleo F439ZI board features an ARM Cortex-M4 based STM32F439ZI MCU with a wide range of connectivity support and configurations. This SoC is basically a clone of the STM32F429ZI with a supplementary hardware cryptographic accelerator.

Supported Features

.. zephyr:board-supported-hw::

Programming and Debugging

.. zephyr:board-supported-runners::

The Nucleo F439ZI board includes an ST-LINK/V2-1 embedded debug tool interface.

Flashing

The board is configured to be flashed using west STM32CubeProgrammer_ runner, so its :ref:installation <stm32cubeprog-flash-host-tools> is required.

Alternatively, OpenOCD or JLink can also be used to flash the board using the --runner (or -r) option:

.. code-block:: console

$ west flash --runner openocd $ west flash --runner jlink

Flashing an application to the Nucleo F439ZI

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

Run a serial host program to connect with your board:

.. code-block:: console

$ minicom -D /dev/ttyACM0

Build and flash the application:

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: nucleo_f439zi :goals: build flash

You should see user led "LD1" blinking.

Debugging

You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: nucleo_f439zi :maybe-skip-config: :goals: debug
