Nucleo F756ZG
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 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 F756ZG board features a ST Zio connector (extended Arduino Uno V3) and a ST morpho connector. Board is configured as follows:
UART_2 TX/RX/RTS/CTS : PD5/PD6/PD4/PD3
UART_3 TX/RX : PD8/PD9 (ST-Link Virtual Port Com)
UART_6 TX/RX : PG14/PG9 (Arduino UART)
USER_PB : PC13
LD1 : PB0
LD2 : PB7
LD3 : PB14
ETH : PA1, PA2, PA7, PB13, PC1, PC4, PC5, PG11, PG13
USB DM : PA11
USB DP : PA12
I2C : PB8, PB9
PWM : PE13
SPI : PD14, PA5, PA6, PA7
Note. The Arduino Uno v3 specified SPI device conflicts with the on-board ETH device on pin PA7.
System Clock
Nucleo F756ZG 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 72MHz, driven by an 8MHz high-speed external clock.
Serial Port
Nucleo F756ZG board has 4 UARTs and 4 USARTs. The Zephyr console output is assigned to UART3. Default settings are 115200 8N1.
Programming and Debugging
Nucleo F756ZG board includes an ST-LINK/V2-1 embedded debug tool interface.
Applications for the nucleo_f756zg board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.
Alternatively, OpenOCD or JLink can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
Flashing an application to Nucleo F756ZG
Here is an example for the Hello World application.
Run a serial host program to connect with your Nucleo board.
$ minicom -b 115200 -D /dev/ttyACM0
Build and flash the application:
# From the root of the zephyr repository
west build -b nucleo_f756zg samples/hello_world
west flash
You should see the following message on the console:
$ Hello World! nucleo_f756zg
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b nucleo_f756zg samples/hello_world
west debug
