Hi all,

in my linker script I use to following settings for heap and stack:

_HeapSize : 0x0;
_StackSize: 10000;

As far as I remember rtems calculates what is left for heap from total mem -
stack. So the zero is ok. But how can I tune the stack figure. Is the figure
specified here the total amount of stack for all tasks?
How can I estimate the StackSize? Is it like:
number of tasks * stack_per_task + what_rtems_needs?
