Re: [lwip-devel] Porting with not threads!

[Erik Ekman]

I think you are looking for the NO_SYS variable, which controls if an
operating system is used or not.

Maybe this is slightly more up to date:
https://lwip.fandom.com/wiki/LwIP_with_or_without_an_operating_system
There is also 
https://git.savannah.nongnu.org/cgit/lwip.git/tree/doc/NO_SYS_SampleCode.c
and the unix port in contrib/ which is pretty minimal.
