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/V3E 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 H7A3ZI-Q board includes an ST-LINK/V3E embedded debug tool interface.
|
|
|
|
Applications for the ``nucleo_h7a3zi_q`` 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 H7A3ZI-Q
|
|
------------------------------------------
|
|
|
|
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_h7a3zi_q
|
|
:goals: build flash
|
|
|
|
You should see the following message on the console:
|
|
|
|
.. code-block:: console
|
|
|
|
$ Hello World! nucleo_h7a3zi_q
|
|
|
|
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_h7a3zi_q
