lwIP sources and ports

lwIP is portable and by no means specific to eCos. It has an active development community and undergoes continuous development of its core code, focussed around its project page on the Savannah development site run by the Free Software Foundation.

The lwIP project releases do include a port to eCos, but that is one of the very first versions of the port, is obsolete and is to be removed.

The public eCos project includes a slightly updated version of the port. However, there are many problems in the port which will result in failure in operation, slower operation, unscalability, and a much larger resource footprint. In addition, the configuration controls are inaccurate and incomplete.

As a result, eCosCentric® decided that in order to provide a robust, feature-rich, and commercially supportable solution for eCosPro®, the port had to be completely overhauled, and mostly rewritten.

This documentation corresponds solely to the eCosPro® port of lwIP, and the usage, configuration system and operation differs in many regards from that in other code bases. In addition, there are several fixes and feature improvements to the core lwIP code base, some of which are exclusive to eCosPro®.
