I hate to cross-post, but I could really use some help with getting the TCP/IP stack working with lwIP and PEx. I posted in the Processor Expert forum, but haven't gotten any responses yet, and since this forum has a reasonable amount of traffic, I thought I'd link to my original post here.
In a nutshell, I believe I have correctly converted the FSL lwip_tcpecho demo application over to work with KSDK 1.1, PEx, and MQX, but even though the code compiles and runs, and stepping through the code line by line seems to be very similar or identical between the two applications, the demo app works (I can ping and connect via telnet), my app doesn't.
I've also attached my application here. Hopefully, someone can take a look and see what I'm doing wrong. In addition, maybe it will help others trying to use lwIP to get a little bit farther with their projects...
