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.

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
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 - “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.

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 |

Arm Mbed OS is an open source embedded operating system designed specifically for the ‘things’ in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices |
|
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 |
