Arduino Portenta H7 (M7 core)¶

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 portenta_h7_m7 ID for board option in “platformio.ini” (Project Configuration File):

[env:portenta_h7_m7]
platform = ststm32
board = portenta_h7_m7

You can override default Arduino Portenta H7 (M7 core) settings per build environment using board_*** option, where *** is a JSON object path from board manifest portenta_h7_m7.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:portenta_h7_m7]
platform = ststm32
board = portenta_h7_m7

; change microcontroller
board_build.mcu = stm32h747xih6

; change MCU frequency
board_build.f_cpu = 480000000L

Uploading¶

Arduino Portenta H7 (M7 core) supports the following uploading protocols:

• cmsis-dap

• dfu

• jlink

• mbed

• stlink

Default protocol is dfu

You can change upload protocol using upload_protocol option:

[env:portenta_h7_m7]
platform = ststm32
board = portenta_h7_m7

upload_protocol = dfu

Debugging¶

Debugging - “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).

Arduino Portenta H7 (M7 core) 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.
