Does anybody have an idea why the settings button is grayed out?

MCU: STM32F412

Other settings seem fine to me:

Thats what I taught...

printf unfortunately does not work with FREERTOS. As well as many other ST HAL functions. If anyone has an idea to make it work, let me know.

Hello @tarmogr ,

Which CubeIDE version is used?

Try to increase the stack size/trace buffer size (window > Preferences > STM32Cube >Serial Wire Viewer).
