Are you using SPI -> Ethernet?  What chip?

Hi Guys

I have an application running on the LPC210x with a 100M LAN over SPI.
The code size is about 14k with ARP/IP/ICMP/TCP/UDP/DHCP incl. small
application with op-sys and necessary drivers. RAM about 3k.Compiled
with IAR compiler...the same program occupies about 30k on an HC12
compiled with GNU.

The uIP TCP stack seems to be rather more efficient but it depends a
lot on just what it really can do - it is possible to support more or
less features in the protocol layers so a comparison is not so black
and white.

A stack with full support could indeed get rather big.
