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:

 

[TCPSERV]

let wiusable sp_cess

bind: lwip_bind(64, addr= 0.0.0.0

lwip_bind: port=5556)

 

tcp_bind: TCP_REG 5e7c40 local port 5556

 

tcp_bind: tcp_bind: bind to port 5556

 

lwip_bind: lwip_bind(64) succeeded

 

[TCPSERV] Listening port 5556

lwip_listen: lwip_listen(64, backlog=1024)

 

tcp_listen_with_backlog: TCP_RMV: removing 5e7c40 from 5e7c40

 

tcp_listen_with_backlog: TCP_RMV: removed 5e7c40 from 5e7c40, new pcb list head 0

 

tcp_listen_with_backlog: TCP_REG 5e7d18 local port 5556

 

lwip_accept: lwip_accept(64)...

 

tcp_listen_input: TCP connection request 44823 -> 5556.

 

tcp_listen_input: TCP_REG 5e83c4 local port 5556

tcp_slowtmr: tcp_slowtmr: processing active pcb

 

tcp_slowtmr: tcp_slowtmr: polling application

 

tcp_slowtmr: tcp_slowtmr: processing active pcb

 

tcp_slowtmr: tcp_slowtmr: polling application

 

tcp_slowtmr: tcp_slowtmr: processing active pcb

 

tcp_slowtmr: tcp_slowtmr: polling application 

 

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