Re: Nucleo F411RE + Arduino 2.1.1: bad combination?
The LD2 not blinking issue may have been changed from LED_BUILTIN` to `D13` and `PA_5`. Your pins need to be correct. STM32 boards may have different pin mappings than regular Arduino boards, so you should double check your pin configuration. Use `PC13` for the default built-in LED.
