I have a project using FreeRTOS TCP 160112 and it works really well. Today I tried upgrading it to 160919 and to my surprise it mostly is not working.
I have been trying all morning to pinpoint exactly where is the issue for me but it is really difficult as, when I use breakpoints to find issues it tends to work. For example, I put for trace using SEGGER RTT message on input and output to get some kind of net trace and if I just let it run, a lot of packets are not even sent. If I put a breakpoint, voila, it stops and once I hit play they are sent.
Before going crazy, are there any documented issues or changes I should do to NetworkInterface.c or to the config that I missed? Using the new version would be great for DHCP callback.
