First test with basic TCP or UDP socket then move to more complex application protocol.

Subject: [lwip-users] LWIP Porting: Issue

 

Hello All,

              I`m trying to port the LWIP into embOS. I have implemented all the required functiones in sys_arch.c. I have implemented simple http server program.

 

              When I execute the code, it is able to initialize tcpip task, and the http task which was created by me. Low level ethernet initialization is also happening properly. 

             

              But when I try to invoke request to this http server from PC browser, it is not replying. I tried to analyze using wireshark. My PC asks who holds the mentioned IP address (for example 192.168.1.3), but my board is not replying to that.

             

              I have no idea how to debug this. Can anyone help me on this? Thanks in advance.

             

              P.S: This http implementation is working fine on baremetal software without any OS.

 

Best Regards,
