I am using STM32F4 EVALUATION Board. I want to implement an echo server based on netconn. I did the configuration of ethenret and tcp/ip and lwip. When I ping it works correctly but when type " C:\>echotool IP_address /p tcp /r 7 /n 15 /t 2 /d Testing LwIP TCP echo server" in the command prompt it shows me this error " reponse time out " I did not understand why it is not working ???
I am so blocked. Can anyone help me please ??
