Thanks Sam, I will try it.

When the data get in the server, it seems to be saved in a buffer automatically. There is no control parameter in tcp_recved(). But in the write function tcp_write(), there is a input parameter p->payload to indicate that from where begin to send out the

By learning the tutorials, now I can get the data and save the data to DDR, and fetch the data from DDR via UART. However, for several days, I can not make the ethernet work. I have studied the tutorial "Getting Started with Microblaze Servers". When I finished the tutorial, I still don't know how to use it in my own project. Actually, I even don't understand what the purpose of each step of the tutorial. The re
