Look http://www.sics.se/~adam/lwip/os.html. It's old, but most of the document is always valid. It explain "how" implement lwip with or without OS. Be careful about multithreading if you use it (lwip core have to be protected against concurrent access), but it's not your case I think. ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr <http://www.hymatom.fr/> ==================================== P Avant d'imprimer, penser à l'environnement

1 In my point of view windows port is the most simple port to start
with .
2 Yes lwip stack can be implemented without sys_arch.c provided that
you understand where the stack should be made thread safe . I have done it by
myself and implemented my own api layer as well .
4 Yes sys_timeouts is pretty confusing but if you implement your
own api layer then you can ignore it all together

Subject: [lwip-users] Example port for a beginner
Hello all , I have few questions on lwip-1.2.0 ( I hope I
have chosen a minimum risk version, is it a stable version)
1 . Any good example of a port that's available for a beginenr
who is trying to port lwip to ppc 83xx.
2. Can I port lwip stack without implementing sys_arch.c at
all. I mean without impelementing semaphore and mailbox funcs.
3 . Should I change or add some stuff in sys.c like in
sys_arch.c.
4. And what exactly does sys_timeouts structure in sys.h
signify ? I see that it's a linked list with each node having time value,
handler and its arguments. Whats the logic behind duch design, why is it a
linked list, does it store different timers each with its own base value,
handler that fires when it hits low or a high ?. I am throughly confused about
this way of dealing with timeouts.
Thanks.
