Enabling Double Precision Instructions on Cortex M7

[Seidleroni]

I am using a STM32F767ZI and I wanted to know how to enable double-precision floating point calculations in my project. I suspect this is not enabled by default, even when when hardware floating point is selected. Is there an easy way to do this?

Hi,

Please try setting the VS Project Properties -> ARM Settings -> Floating-point unit type.

You can read more about various FPU options supported by GCC here: https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html
