I'm actually trying to implement the LWIP stack on a PowerPC inside a Xilinx FPGA virtex5. I start with the web server example and add some modifications in order to match my needs. It seems to work but not as well as i need. I mean i'm able to send and receive data but when i send data during a long period of time it seems that some data are lost. When i say lost i don't mean "the packet is lost, should be resend" message if you check with a wireshark like software, i mean the data never reach the Lan card (the data doesn't appear in wireshark like software). I know that data are missing cause i know exactly the number of frame that i'm sending to my computer from the PowerPC and i'm able to calculate the number of frame that i receive on the computer side.

Since i'm a newbie with the LWIP stack and i'm not a software development specialist, i'm looking for someone that can help me to debug my code using the LWIP.

Thank you a lot,
