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:

platform = ststm32@~6.1.1
framework = arduino
board = nucleo_h743zi
