[lwip-users] Minimum for TFTP client

[Mathias Zenger]

I would like to write an ethernet boot loader for my embedded system. A
small TFTP client shall be part of the bootloader. The client shall be based
on the raw API (code size is critical). Can somebody explain me which bare
parts from lwIP (or perhaps uIP) I shall use to get a basic TFTP
communication working? I guess I would need ARP, IP and UDP (but which
files?). Would be great if somebody even could provide a functional example.

Regards,
Mathias
