How to get the data from lwip?

Hi Sophia,

I personally haven't used lwip, so I'm not able to directly answer your question, but I imagine (coming from more of a C++ based background where this sort of suggestion is fairly straightforward) you would want to first be able to collect the data from using lwip and then write it to BRAM. Here are a couple of places that I have found that discuss how they might get data from lwip (as opposed to just confirming it was received) here and here. Here is a Xilinx thread talking about how they would read and write data into BRAM; it's for a Spartan 3A, but I imagine that the guides that are referenced in that thread also exist for Zynq chips.

Thanks,
JColvin
