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.
