Hello Andrew,
I never used DHCP with lwIP here so I never discovered this problem. I
used a fixed IP address to run the tests. Today I compiled the tests
with DHCP support and tried to debug them but insight did not list the
dhcp.c file in its sources. I inserted an #error message into the dhcp.c
file to check if it is built - it is. So it must be linker garbage
collection because the dhcp functions are simply not referenced anywhere
in the code. I checked the lwip code and there is not initialisation for
dhcp and also the timer functions dhcp_fine_tmr() and dhcp_coarse_tmr()
are never called.
So obviously Jani Monoses, who contributed the original lwIP patch, also
never used DHCP ;o) I will try to add DHCP support as soon as I have the
time (maybe in some weeks). At least my patch did not broke DHCP support
- so please try a fixed IP address when testing.

ecosconfig new linux lwip_eth
then enabled dhcp. I then built eCos and the lwip tests. I found that
it does not send anything out the ethernet port. Enabling debugging it
looks like it is not adding the ethernet interface, there is only the
loopback interface.

Am i doing something wrong?
