Nucleo H723ZG

Overview

The STM32 Nucleo-144 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller. For the compatible boards, the internal or external SMPS significantly reduces power consumption in Run mode.

The ST Zio connector, which extends the ARDUINO® Uno V3 connectivity, and the ST morpho headers provide an easy means of expanding the functionality of the Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo-144 board does not require any separate probe as it integrates the ST-LINK V3 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 H723ZG 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

  • SPI1 NSS/SCK/MISO/MOSI : PD14/PA5/PA6/PB5 (Arduino SPI)

  • FDCAN1 RX/TX : PD0, PD1

System Clock

Nucleo H723ZG 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 550MHz, driven by an 8MHz high-speed external clock.

Serial Port

Nucleo H723ZG 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 SB52 jumper on the back side of the board.

FDCAN

The Nucleo H723ZG board does not have any onboard CAN transceiver. In order to use the FDCAN bus on this board, an external CAN bus transceiver must be connected to pins PD0 (RX) and PD1 (TX).

Programming and Debugging

Nucleo H723ZG board includes an ST-LINK/V3 embedded debug tool interface.

Note

Check if your ST-LINK V3 has newest FW version. It can be done with STM32CubeProgrammer

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 H723ZG

First, connect the NUCLEO-H723ZG to your host computer using the USB port to prepare it for flashing. Then build and flash your application.

Here is an example for the Hello World application.

Run a serial host program to connect with your NUCLEO-H723ZG board.

$ minicom -b 115200 -D /dev/ttyACM0

or use screen:

$ screen /dev/ttyACM0 115200

Build and flash the application:

# From the root of the zephyr repository
west build -b nucleo_h723zg samples/hello_world
west flash

You should see the following message on the console:

$ Hello World! nucleo_h723zg

Blinky example can also be used:

# From the root of the zephyr repository
west build -b nucleo_h723zg samples/basic/blinky
west flash

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_h723zg samples/hello_world
west debug
