[lwip-users] lwip memory on a xilinx ml403 dev board

[kyle treleaven]

Hi all,

I'm trying to use the Xilinx-provided port of lwIP on a PPC405
(embedded) running the "standalone" OS-- ie. no OS.  I'm using the raw
API, and I've simply compiled a bit of tutorial code (a small echo
server) provided in an appnote by Xilinx-- I'm sure a lot of people
have run the same drill.  But for some reason my compiles keep running
up in the 800K range, which is way way way too big for my poor little
fpga.  Plus it seems ridiculous when compared to the "tens of
kilobytes" that everybody else claims on other platforms.  My mem/memp
settings are (the defaults):

MEM_SIZE: 8192
MEMP_NUM_PBUF: 16
MEMP_NUM_UDP_PCB: 5
MEMP_NUM_TCP_PCB: 5
MEMP_NUM_TCP_PCB_LISTEN: 5
MEMP_NUM_TCP_SEG: 255

I'm under the impression that these are the only settings that matter
for raw api use.

Has anybody else had this problem? Anybody know what's going on?

Kyle
