These sys_timeout log entries are normal, as far as I know. They are
output when lwip checks for timeouts on blocking operations. You should
probably just disable "System debugging" in the debug options.
Further: How do I send tcp-packet to port 7. Will a browser where I
enter 192.168.0.10:7 send a tcp-package to port 7?
Use a telnet session. You should get echo's of whatever you send to the
target. Note that telnet sends data when you hit the 'return' key.

Hi
I have continued to experiment and I am happy to report that the test
program httpd_sequential.c builds and executes. But only if I build the
library with a fixed IP-address for my board. When changing this to
DHCP, I can no longer reach the http-server running on my board.
Using wireshark, I can see (see attachment) that the there is a hopeful
beginning of the DHCP configuration process of my board. But there is
never a fitting answer from the ZyXEL which implements the DHCP-server
on our LAN - at least as far as I see it, given my rather limited
experience with network issues..... Has anyone out there a possible
explanation what's going wrong here?

More to the above:
In the debug output of the program I see that there is a package to my IP
192.168.0.10, but it is dropped because of a checksum error. I do not know
why I cannot see this package in wireshark - and I do not know why there
is a checksum error - obviously a consistent one which repeats each time I
run the program. I think I have to check memory usage in my
configuration.....
