Hi everyone,

I have TSE MAC at my custom board and RGMII interface between custom board and PC.

Mode of communication established between custom board and PC is 100 Mbps half duplex.

I made my custom board as Client and PC as Server.

Using TCP sockets.

I am sending data continuously ranging from 8 bytes to 424 bytes of data depending on my application from my custom board to a PC. Sometimes I send 4 bytes of data from PC to Custom board for configuration of my application.

Problem is that my NIOS II system does't responds sometimes and Communication ends between custom board and PC.

I have kept descriptor memory size of 8192 bytes in SOPC Builder. I haven't change anything in ipport.h

What might be the problem and solution to it ?????
