Serial monitor failure STM nucleo l432kc

Hello everybody,

i am struggling with my serial monitor.
The baud rate is initiated with 115200 via platform.ini. As well as is the baud rate set
in my uart initialization.

But this is what I get on my serial monitor.

Does anyone have the same problem since platformIO got an update for the stm platform?

Okay guys,

nevermind. It turned out that there exists a problem with my stm and the new platform update 10.0.1. So downgraded it to 5.6.0 and it works again.

Using the newest platform should not break the UART functionality of your board. Downgrading is not the right fix here…

What exact platformio.ini and code do you have?
