Hi, thanks for your help. Here is a better desciption of my system: TI TMS570LS3137 with lwip1.4.1 has IP 192.168.1.165 and FreeRTOS running a PLC. The other side is a PC with Windows7 (IP 192.168.1.99) and the PLC control application. I've started with the TI port for lwip and (as you guessed right) changed it to call the stack from a task. But I see the same issue if I call it from the ISR.
If the frame 1513 coming from lwip gets lost somewhere why do I see an ack from PC for this frame in frame 1514? If I get an ack for a frame, it must have been received by the other side, isn't it?
