However you would want to frame it - your Flash is too small, or you want to cram too much code into your Flash.

Try some compiler optimisation settings, preferably optimising for size.
Check the linker removes unused code.
Consider removing unnessesary libraries, or smaller versions with reduced functionality (libnano).

Or, take an MCU with more Flash.
