Note

Starting with this release, the native libopencm3 tool is used for generating linker scripts. This may cause linking issues with legacy projects.

7.2.0

We're happy to announce updated support for the new Mbed OS 6 with stable and mature APIs, Cloud services support, Enhancements to the Bare Metal Profile. For boards which don't support the latest Mbed release, Mbed OS 5 remains as the default choice. The list of deprecated boards in Mbed OS 6 can be found here.

Update support for mbed framework:

• Update Mbed OS6 to v6.2.0 (release notes)
• Update Mbed OS5 to v5.15.4 (release notes)

Please note

Due to breaking changes in Mbed OS 6 existing Mbed projects might not be compatible with the latest API changes. In order to keep legacy projects built on top of Mbed OS 5 compilable, a list of deprecated boards is used to dynamically select the proper version of Mbed OS (OS5 or OS6). To force the platform to use Mbed OS 5, specify the Mbed package version using platform_packages option in platformio.ini file:

[env:nucleo_f401re]
platform = ststm32
framework = mbed
board = nucleo_f401re
platform_packages =
    framework-mbed @ ~6.51504.0

More information on project configuration for Mbed framework can be found here.

7.1.1

7.1.0

• Added new board 96Boards AreoCore 2
• Updated Zephyr framework to v2.3.0 (release notes)
  • Added support for MenuConfig target
  • Minor bugfixes and improvements

7.0.0

• New boards:
  • WeAct BlackPill V2.0 (BlackPill F411CE)
  • Electrosmith Daisy
  • FYSETC S6
  • ST STM32G0316-DISCO
  • PYBStick Duino 26

  • genericSTM32F4x
• Updated Arduino STM32 core to v1.9.0 (release notes)
• Updated support for CMSIS framework:
  • Updated CMSIS package to v5.5.1 (release notes)
  • Added support for the official CMSIS Device MCU Components from STMicroelectronics
• Minor bug fixes and improvements

Please note

Starting with this release several possible breaking changes are introduced:

• Arduino
  • The STM32Duino core is used by default for all boards (except Maple boards).
• CMSIS
  • New CMSIS device packages may cause bigger firmware size due to new startup files and updated linker flags
  • Updated default linker scripts

If some of the changes above are not acceptable for you project, you can set the previous release in the platformio.ini file:

[env:nucleo_h743zi]
platform = ststm32@~6.1.1
framework = arduino
board = nucleo_h743zi
