Nucleo G474RE

Hardware

Platform ST STM32: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller STM32G474RET6
Frequency 170MHz
Flash 512KB
RAM 128KB
Vendor ST

Configuration

Please use nucleo_g474re ID for board option in “platformio.ini” (Project Configuration File):

[env:nucleo_g474re]
platform = ststm32
board = nucleo_g474re

You can override default Nucleo G474RE settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_g474re.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nucleo_g474re]
platform = ststm32
board = nucleo_g474re

; change microcontroller
board_build.mcu = stm32g474ret6

; change MCU frequency
board_build.f_cpu = 170000000L

Uploading

Nucleo G474RE supports the next uploading protocols:

  • blackmagic
  • jlink
  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:nucleo_g474re]
platform = ststm32
board = nucleo_g474re

upload_protocol = mbed

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Nucleo G474RE does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
Black Magic Probe   Yes
J-LINK    

Frameworks

Name Description
Arduino Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.
CMSIS The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices.
Zephyr The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind.
