    • Printf support for semihosting/ITM debugging for float variables.

    I cannot get sprintf to work with floats either.

    I checked the linker script and the _estack is fine

    _estack = 0x20020000; /* end of RAM */

    I am using an M4 and have the Hard FPU selected.

    How do I enable printf with float?
