[lwip-users] LWIP TCP Connection not getting established

[Arpit Agarwal]

Hi,

 

I am trying to use LWIP 2.0 RC2. I am unable to establish TCP connection while this didn't happen in LWIP 1.4.1.

The connection request is hitting function tcp_listen_input , but after that nothing happens.

Please find the los below:

Please help me in finding out what's going wrong.
