Hi.

I am new in here with first time to post it. I tried to use the ethernet with LwIP for stm32f407ve LQFP-100. With source of LwIP provided by STMicro electronics, I tried tcp-echo-server. But after working with long, Failure was happened. It is like this, Ping was alive, but TCP/IP was not alive. Please hint me how to solve it. Thanks ahead. Kevin #debugging #ping #icmp

Ping uses ICMP - it does not use TCP
