Hi
I have included the package lwip_tcpip in my library and now I want to run
the test programs that come with it. But how? Take e.g. tcpecho. I built
it using my library, then download it into my at91sam7x256-based board and
run it. Nothing happens. What should happen? What "special actions" am I
supposed to do? Thanks for help.

Do you see any diagnostic output on the serial port?


TCP echo test will simply echo everything that's sent to the open test port. You can for example use telnet or netcat to send some strings to the device and get the echo responses.

Hi Simon
yes, I see some messages on ser1. It appears every few seconds, but I get the impression there is no answer comming back. I also hooked my PC to the LAN with wireshark and there as well, I see nothing originating from my board.


tcpecho: When attempting to connect to my board (where tcpecho is running) with telnet 192.168.0.222 I get the message

telnet: Unable to connect to remote host: No route to host

I have the feeling its a hardware problem. The LEDs on the switch I am connected to with this board also remain dark all the time.
