Hi,
Is there an easy way to know where in memory (exact address) the stack
is located?
In my case (at91sam7se, arm7) the stack size is limited depending on
the address it is located at.
I think the heap should be located at the high end of RAM, but I
haven't got a clue where to look for the stack.

Which stack? There is the interrupt stack and the idle stack, which
could be the same. If you don't have your own main() function there is
also a system main() which has a stack. Plus all your threads have
stacks.
arm-elf-objdump --syms myprog.elf
or
arm-elf-nm myprog.elf
will show you the symbol table with addresses for all symbols.

Thanks.
I was looking for stack of my main function. I don't use multiple
threads, so that's one thing less to worry about.
