Overview
********

The STM32 Nucleo-144 boards offer combinations of performance and power that
provide an affordable and flexible way for users to build prototypes and try
out new concepts. For compatible boards, the SMPS (Switched-Mode Power Supply)
significantly reduces power consumption in Run mode.

The Arduino-compatible ST Zio connector expands functionality of the Nucleo
open development platform, with a wide choice of specialized Arduino* Uno V3
shields.

The STM32 Nucleo-144 board does not require any separate probe as it integrates
the ST-LINK/V2-1 debugger/programmer.

The STM32 Nucleo-144 board comes with the STM32 comprehensive free software
libraries and examples available with the STM32Cube MCU Package.

Programming and Debugging
*************************

Nucleo H753ZI board includes an ST-LINK/V3 embedded debug tool interface.

Applications for the ``nucleo_h753zi`` board configuration can be built and
flashed in the usual way (see :ref:`build_an_application` and
:ref:`application_run` for more details).

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 Nucleo H753ZI
----------------------------------------

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

Run a serial host program to connect with your Nucleo board.

.. code-block:: console

   $ minicom -b 115200 -D /dev/ttyACM0

Build and flash the application:

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: nucleo_h753zi
   :goals: build flash

You should see the following message on the console:

.. code-block:: console

   $ Hello World! nucleo_h753zi

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_h753zi
   :maybe-skip-config:
   :goals: debug
