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.

Default Zephyr Peripheral Mapping:

The Nucleo H743ZI board features a ST Zio connector (extended Arduino Uno V3) and a ST morpho connector. Board is configured as follows:

UART_3 TX/RX : PD8/PD9 (ST-Link Virtual Port Com)
USER_PB : PC13
LD1 : PB0
LD2 : PE1
LD3 : PB14
I2C : PB8, PB9
ADC1_INP15 : PA3
DAC1_OUT1 : PA4
ETH : PA1, PA2, PA7, PB13, PC1, PC4, PC5, PG11, PG13
SPI1 NSS/SCK/MISO/MOSI : PD14/PA5/PA6/PB5 (Arduino SPI)
CAN/CANFD : PD0, PD1

System Clock

Nucleo H743ZI System Clock could be driven by an internal or external oscillator, as well as the main PLL clock. By default, the System clock is driven by the PLL clock at 96MHz, driven by an 8MHz high-speed external clock.

Serial Port

Nucleo H743ZI board has 4 UARTs and 4 USARTs. The Zephyr console output is assigned to UART3. Default settings are 115200 8N1.

Backup SRAM

In order to test backup SRAM you may want to disconnect VBAT from VDD. You can do it by removing SB156 jumper on the back side of the board.

CAN, CANFD

Requires an external CAN or CANFD transceiver.

Programming and Debugging

.. zephyr:board-supported-runners::

Nucleo H743ZI board includes an ST-LINK/V2-1 embedded debug tool interface.

Applications for the nucleo_h743zi 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, JLink or pyOCD 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 $ west flash --runner pyocd

Flashing an application to Nucleo H743ZI

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_h743zi :goals: build flash

You should see the following message on the console:

.. code-block:: console

$ Hello World! nucleo_h743zi

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_h743zi :maybe-skip-config: :goals: debug
