I wanted to printf float value , so I set CONFIG_CBPRINTF_FB_SUPPORT=y in my prj.conf file, my application code succeeded to printf float value.
then I wanted ot use sqrt and acos in math.h , so I set CONFIG_NEWLIB_LIBC=y and I could use these math function.but the printf float value failed
for example , I printf("test data %f",0.5) in my application , I only get test data without 0.5 in my log out
is there any configuration I need to set ,when I use newlib_libc and also want to printf float value ?
