Re: [lwip-users] lwIP instead of BSD stack regarding IPv6

[Ivan Delamer]

Hello Christian,

I think eCos only comes with LwIP 1.3.2 which does not support IPv6.

For IPv6 support you need to get the latest version, 1.5.0 BETA, or get 
the current HEAD development version from the GIT repository.

There were some API changes from 1.3.2 to 1.4.0 (1.5.0 API is more or 
less the same). So you'd have to make some changes to sys_arch.c and 
related files, and to your netif driver as well. Also include some new 
source files in your makefile.

IPv6 support is in BETA stage, however some of us have been using it 
for over 2 years.

Cheers
Ivan
