connect in linux-socket

I am doing tcp client project using arm proccessor with uclinux.
my tcpclient.c code working when I use switch-hub to connect to server.But can't work when I use cross cable to connect.what do you think about this.
thanks for advice
 

well. did you make sure that all the IP addresses are static when using a cross cable? I'm doing my project on a cross cable and sockets work perfectly. I only had a problem with dhcp and firewall blocking incoming connections.
 

I want to connect one device from ethernet port.Device is working as a server.
I am connecting to device with my pc(as a client) using cross cable.
I am connecting to pc(as a server) with my embedded card(as a client) using cross cable.
But I can't connect to the device(as a server) with my embedded card(as a client) using cross cable.I can connect to the device through switch hub.(using 1-1 cable)
