Sorry for the wrong bug.

Simon . You are correct. The issue with the port to the OS. The system abstraction layer was bit incomplete , which caused me the issue. Now it is fixed after re working on the sys abstraction layer.

Please close/delete this bug .

Thanks

What evidence do you have this is a bug in lwIP? Do you know that the port to the mynewt thing is working correctly? I strongly suspect this is not a bug in lwIP but a bug in your port or application. In that case, this bug tracker is the wrong place for this issue.

Hi ,

   I am using lwip 2.0.2 on the mynewt OS (RTOS). Trying to make a netconn based server app on STM32 based ethernet device
To test this app i am using a simple linux based tcp client program on my PC.(STM32 device and PC are connected to same network)

  I am getting issue like netconn_accept is not coming out of the waiting state, even though the client is connected to it. I confirmed this from the client side as it is connected to a server.

  Even though the server is responding to client request , netconn_accept coming out of the wait state .


Any idea ?

Thanks
