This can sound a weird problem,I have some float variables added in expression window,which doesnot show up its value and neither printf support float variable.
I changed properties as
by going to Project -> Properties -> C/C++ Build -> Settings -> Cross ARM C Linker -> Miscellaneous -> User float with nano printf
I don't understand reason for it.
watch window also doesnot show float variable ,just shows nan as above
