Strange math.h behaviors

Hi,

I am evaluating CrossStudio with STM32H7.

I wrote a small FFT benchmark I am trying to test.

Every time I am using an Arm Library function like arm_cfft_f32 or arm_fill_f32 etc, I can see the stack is getting messed up and some of the variables or the arrays getting strange values.

Any help will be greatly appreciated.

Thanks

Sharon

  It sounds like you are running out of stack - try increasing the stack size ( https://rowley.zendesk.com/hc/en-us/community/posts/205386943--change-the-stack-size-of-my-application- )

  Right click on your project in the project explorer and select Edit Properties then enter the word stack into the Search Properties field at the top of the dialog - this will show you all the stack properties.
