Troubles with 10 Bytes by sending every 10 miliseconds

Question

I’m using the W5300 in TCP mode with a Spartan6 FPGA at 250Mhz. When I set the registers of the W5300 every 100 milliseconds for sending 10 Bytes data it work fine. The Connection open and closing every time. When I set him every 10 milliseconds he don’t communicate over the Ethernet. How can I send data faster with the chip?

Thanks for you’re reply. At the endresult I need to send 3500 bytes every millisecond, so thats 3.5MBps. When SSR is Established, I do the next steps: Check S0_IR_CON and Clear him Write the data in S0_TX_FIFOR Set S0_TX_WRSR set S0_CR_SEND to ‘1’ next I check S0_IR1(SENDOK). If the bit become to ‘1’ I clear the bit. If the socket is closed before SENDOK become to ‘1’ or I cleared SendOk, I return for checking the SSR. Need I, and is it posible to, get open the connection for sending these 3.5MBps or is there another solution?

Thanks for you’re reply. I have fix it. I used a slow TCPserver in Delphi, that was the problem. Now I’m using a faster way to receive the data. Thanks for you’re help.
