modified to update the external flash memory on Einsy boards.
Due to a bug in the USB to serial converter firmware on the Prusa Einsy
boards, the STK500 protocol has been modified to never send semicolon
characters towards the main processor.
This firmware updater is compatible with a modified avrdude using
the "arduino" protocol, see the following commit.
https://github.com/prusa3d/Slic3r/tree/fwupdater_languages
printf float library enabled - platform.txt must be modified!
+flash usage optimalization - printing to serial line
current flash usage: 253206bytes (MK3 + ML support)
platform.txt original line 20:
compiler.c.elf.flags=-w -Os -Wl,--gc-sections
platform.txt modified line 20 (enable printf float library)
compiler.c.elf.flags=-w -Os -Wl,-u,vfprintf -lprintf_flt -lm -Wl,--gc-sections
Another fix from PR https://github.com/prusa3d/Prusa-Firmware/pull/138 and discussed in Issue https://github.com/prusa3d/Prusa-Firmware/issues/807
