ST Nucleo L4R5ZI¶

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.

Configuration¶

Please use nucleo_l4r5zi ID for board option in “platformio.ini” (Project Configuration File):

[env:nucleo_l4r5zi]
platform = ststm32
board = nucleo_l4r5zi

You can override default ST Nucleo L4R5ZI settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_l4r5zi.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nucleo_l4r5zi]
platform = ststm32
board = nucleo_l4r5zi

; change microcontroller
board_build.mcu = stm32l4r5zit6

; change MCU frequency
board_build.f_cpu = 120000000L

Uploading¶

ST Nucleo L4R5ZI supports the next uploading protocols:

• jlink

• stlink

• blackmagic

• mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:nucleo_l4r5zi]
platform = ststm32
board = nucleo_l4r5zi

upload_protocol = mbed

Debugging¶

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

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

ST Nucleo L4R5ZI has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
