Question: Enable floating points in platform.txt #266

I have tried the various suggestions on the Internet for enabling floats in sprintf on the AVR in platform.txt but they do not seem to enable on Mightycore.

Am I missing something or is it missing the support in the Mightycore files?

Actual place they have to be placed in platform.txt is different than most recommendations - correct location is:

compiler.c.elf.flags=-Wl,-u,vfprintf -lprintf_flt -lm {compiler.warning_flags} -Os -Wl,--gc-sections,--section-start=.FAR_MEM1=0x10000
