Hi,

I am trying to do FFT using stm32f4 discovery board. I am using CooCox CoIDE. After adding DSP Libraries and everything I am getting this problem during Compile.

CAN anyone help me in this

Thanks, Pochamreddy. #discovery #stm32f4 #!stm32-!fft #fft

Don't know Coocox IDE internals, but obviously you link against the wrong math library.

> [cc] arm-none-eabi-gcc -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -

mfloat-abi=hard

... > ...> error: stm32f429_project.elf

uses VFP register arguments

, C:\CooCox\...\lib\libm.a(lib_a-wf_sqrt.o)

does not

  If the IDE/wizard selected the libm.a, or you did it manually, it is the wrong one. Either point your project to the correct library, or use

-mfloat-abi=soft_fp

, which is only marginally slower than '

hard

'.
