Hi @Raghavender,

I'm not sure which Zynq Ultrascale board you are using, though those of us at Digilent aren't too familiar with freeRTOS materials or the intricacies of the lwIP socket server.

A couple of things that I would probably try though would be to see if setting the phy_link_speed to 100 Mbps yields the same error (this line of thinking comes from if the routers/switches in your work environment are 100 Mbps rated rather than gigabit). It also looked like the DHCP server timed out which could mean that the board IP settings are not the same as the network it was connected to (or that no DHCP server is available); it seems from the ipconfig that both the computer and the board are on the same subnet, though it won't hurt to check this.

Thanks,
