Even if there is a date, I hope 1.3.0 will be released before the end of the
year. Else, you can get the last CVS HEAD.
First, which features do you need ? Do you have disable most of options you
don't use?

configuration-HELPME!!
i found in init.c file in current CVS some options deprecated:
now i'm linking the 1.2.0 version... i didn't have this file....
have i wait a 1.3.0 version? or get cvs version (beta?)? or use 1.2.0?
and... please someone tell me something about other issues in my email.
Thanks Frédéric!

There is some indications in init.c , in the last CVS HEAD. Take a look on
lwip_sanity_check and on previous preprocessor checkings.

Hi all.
Can someone help me to understand options in opt.h (LWIPopt.h) which
change memory usage?
what are limits for each option? (for example NOT LESS THAN...)
How each option is connected to others? (for example: options for
sequential API and options for tcp and udp connections... )
can i change pbuf options? (PBUF_POOL_BUFSIZE..... )
in particular, i want to understand how reduce the following variables:
- ram
- memp_memory
- pbuf_pool_memory
depending on number of simultanely connections (TCP, TCP LISTENER, UDP)
(i have to use socket for apllication porting reasons)
Correct me if i'm wrong:
the total memory depends on 3 things:
- memory for low level driver, where MAC layer puts ethernet frames
- memory for LWIP (the above discussion)
- memory for application task, which use sequential API and needs a
owner buffers
is it true?
PLEASE HELP ME!
i'm working on an example which use:
- LWIP (1.1.1.. but i will update to 1.2.0) (ported from GNU to IAR)
- FRERTOS FOR ARM7 (lpc2368 microcontroller)
- lpc2368 EMAC driver
i'm having a lot of problem, and i have to reduce memory usage...
and at the last (....) i have to understand how to use lwip!!!
Bye,
Piero
