AVR32 lwIP Collections

AVR32 is a microprocessor architecture designed by Atmel. AVR32's lwIP example contains HTTP, TFTP and SMTP services. 

lwIP (lightweight TCP/IP)  is a free TCP/IP stack for many embedded processors, it is originally written by Adam Dunkels at the CNA lab of the Swedish Institute of Computer Science.

The following are notes taken during my experiments on the above platforms.
