The ST Cube software generated a version of LWIP with version 1.5 but I cannot find such a branch or tag in the git repository. I did
find this which suggests that 1.5 was the first version to implement IPV6 and it seems to have been the basis for 2.0.
My ultimate goal is to use 2.0 but I wanted to get something that was known to work up and running first. I'm asking because I'm not quite sure which documentation to reference.
From the 'Cube' version:
#define LWIP_VERSION_MAJOR 1U
#define LWIP_VERSION_MINOR 5U
#define LWIP_VERSION_REVISION 0U
#define LWIP_VERSION_RC 0U
Best regards,
Kenny
