That's obviously a bug in the Xilinx port, not in lwIP.

We don't, please ask on the lwip-users mailing list.

Dear Experts
We use lwip version 1.40_V2_2 library for network  in our zynq 7000 based project.
Zynq 7000 is a product of Xilinx company .
It works perfect when we test it for short period of time.
But following error occurred on long time test:
Our system runs into an exception ( called Xil_PrefetchAbortHandler) and we could not send any new packet to our zynq board.
This bug is the result of receiving a lot of packets or receiving a single packet after a while the connection was established.
We do not use freeRTOS and run our program in bare metal mode.

Do you know how we could resolve it?
BR
Mohandes,
