I could tell you another story about how well lwIP ran on my ARM7, but
I'd like to question the significance of the statement "never seen lwIP
work on an ARM7"... If it has a C compiler, it runs! (of course, you
need an ethernet MAC also...)
You have to be careful about using the word GCC, I guess: at first, I
compiled lwIP with the C++ compiler of GCC, which lead to many warnings.
But using the C compiler, I'm pretty sure there are no warnings
generated (unless you use one of the more chatty warning switches).
Of course you need someone to write an OS/platform port (unless you want
to do it yourself), but apart from that, there's no reason I can think
of that lwIP wouldn't run on an ARM7!

P.S.: If you really want to get it running, it might help to know which
version you are using. Also, take a look at the example ports in the
contrib module (accessible via downloads or CVS) and at the lwIP wiki.

Hi:
I'm trying to get the above working, so far I can't even get a ping.
I think the code set is full of loose ends. I tried lwIPweb also, and
it has a ton of loose ends too. Undefined vars and consts come up
everywhere, and I have to make guesses about what the fixes need to
be. I have to make lots of corrections just to get it to compile.
But when I run it not much happens.
Richard of FreeRTOS made the statement that he has "never seen lwIP
work on an ARM7". Yet the guys that created the modified set of
lwIPweb says it does. Yet there are others reporting a variety of
bugs that need to be fixed. Very confusing.
Also, even after I fix the errors to get it to compile, GCC gives a
ton of warnings on the lwIP code. Some of them look fairly serious.
Does anyone have anything of lwIP working on an LPC23XX/LPC24XX ? If
so I'd love to get a zip'd copy of your file set to see what you've
got that actually compiles and works.
Regards, Chris.
