[En-Nut-Discussion] ATMAN compiler

[Harald Kipp]

Zhao,

I do not know much about the Atman compiler, but your
problem appears because of wrong linker options. At least

--defsym=main=0

is missing.

With Nut/OS, main() is a thread, started by the idle thread.
The stack of the main() thread is set in NutThreadCreate().

Nut/OS redefines main() as NutAppMain() to avoid GCC's attempt
to re-initialize the stack on main() entry.
