Hi ;

I have been trying to solve it with 4 days but I could not !

I have an old Project that I need to fix some bugs

I have a bufffer defined as :
float volt[1125];

in the new version I have to add pace_volt[18000]// 4khz sample.

when I write to volt any value ;   to all buffer all some of it

in my code I have to update volt by :



   for(i=0;i<1123;i++)
   {
   
  volt[i]=pace_volt[i];

   }


the function 
 /* Process the data through the CFFT/CIFFT module */
 arm_cfft_radix4_f32(&S, testInput);

give an handfualt_handler !!

when I dont write to volt it is ok ..
but I need to write to volt !!

Could you guide me please to solve it?

Note: FPU is enabled 100% .

Thank you in advanced
