Hello All, I need to implement TCP/IP through lwip stack on AT32UC3A0512. I tried using the BSD sockets of lwip stack to establish TCP/IP, but I can never ping successfully, the connected ATEML EVK1105 board.
Ethernet driver are working perfectly. I think some change needs to be done to LWIP stack to create a Socket properly and send data. Pinging is failing and Data communication is failing. Please let me know a solution for this. Thanks and Regards Abhijith N.M. ________________________________________ From: [email protected] [[email protected]] on behalf of [email protected] [[email protected]] Sent: 07 September 2015 23:55:15 To: Mailing list for lwIP users Subject: Re: [lwip-users] Call tcp_close() out of tcp_recv()-context?

No. Unless you take special action to prevent concurrent access to the lwIP core (i.e. block ETH IRQ when calling lwIP functions from main loop), receive functions must not be called from ISR. If that is the case, most often the creator of your lwIP port has done something wrong. This has been the case for some microcontroller vendor's ports in the past.
