[lwip-users] Incoming TCP rejected on ARM

[Mykola Kyrylenko]

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'.
http://www.nabble.com/file/p25167221/lwipopts.h
lwipopts.h
If any more information is required, I can provide.

Any assistance will be most appreciated.

regards,
Mykola
