Error compiling for board Arduino Nano Every.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Any idea how to solve?

Compiling for the Mega works fine :slight_smile:

Thanks for your inputs

There is a bug in Print.h in the current version of the megaavr core.
