It's because I was adding the flag with quotes.

add_link_options(-u _printf_float)

works. Thanks

Hi,

Could you try snprintf() to see if it gives you the same result? It should work as long as you build with -u _printf_float

Found it to be too much of a hassle to work with floats on ARM chips. Mostly convert my numbers in code to there base value eg. 1.675V converts to 1675mV. Then add the decimal on the user interface side with string converters.
