I've attached the FPU unit and now everything works (ofc this is the obvious)

sorry for wasting ur time about that =)

I changed the FPU to this one at alterawiki: http://www.alterawiki.com/wiki/configurable_fpu

I am testing with this code 


# include <stdio.h>
int main()
{

  float c = a * b;
  printf("c = %f\n", c);
  return 0;
}

And everything works fine
