MuratI have two boards that I developed using STM32F1 with PHY
I used standard tcp_echoclient and tcp_echoserver codes in lwip.
That two boards connect and accept all connections coming from PC via Hercules Software.
So there is no problem on my codes and hardware.
But when I want to connect tcp_echoclient to tcp_echoserver, tcp_echoserver does not accept the request coming from tcp_echoclient.
Client state shows SYN_SENT andServer state shows nothing
But as I said the client and server can connect to the PC successfully
What can I do in this situation?Thanks
