printf prints blanks instead of floats

[matthieu]

Same question as devzone.nordicsemi.com/.../

What needs to change for a gcc setup in the compile flags. If that helps, some of the flags I have now include:

-mfloat-abi=hard -mfpu=fpv4-sp-d16

Found the answer there: devzone.nordicsemi.com/.../

Basically add

LDFLAGS += -u _printf_float
