can't watch local variable

Static works, thanks..

But there are other problems.
I made this function:

void Main_make_sprintf_work(char * str)
{
  static char str_local[40];
  sprintf(str_local, "%f" ,2.45);
  memcpy(str, str_local, 10);
}

It works when I call it from main() but don't work if the call come from a function further inside the program.

In what way does it "not work"?

When I call Main_make_sprintf_work(char * str)
from a task, str_local don't contain the right string.

After adding 500 bytes to the stack (now 1500 bytes) it writes "2" in Str_local.

I think its strange it did not detect any stack overflow and why do it need so much stack?

The problem was that I had an RTX_Config file for V3.02 and my IRQ and USR stack size was too small.
