Hi,
I am trying to get LwIP working on a STR912 processor, using callback
(no OS).
It all compiles well, and ICMP works (I can ping the device).
When trying to connect to a TCP socket (httpd, telnetd or netio), the
connection does not get established.
Comparing with Ethereal, the packet appears to be interpreted correctly,
and passes through 'ethernet_input()' and 'ip_input()' with no problems.
It seems to bail out in 'tcp_process()'.
Netio execution
D:\>netio -t 192.168.1.121
NETIO - Network Throughput Benchmark, Version 1.26
(C) 1997-2005 Kai Uwe Rommel
connect(): error code 10060
Below is a dump for 'netio'.
Attached is 'lwipopts.h'.

lwipopts.h
If any more information is required, I can provide.
Any assistance will be most appreciated.
regards,
Mykola
