Hi every one!
I have got strange problem i searched solution on forum but nobody have the same problem.
I generated system using EDK, based on ML605 board. I add axi timer (marked using interrupt), next i add AXI Ethernet Embedded IP and also mark using interrupt. In SDK i use sample project LwIP echo example. When I run the application in hardware sometimes everything works fine for a while. I can connect to server using telnet. By when i send data for a while the application is suspend. It doesn't response for a ping. I must restart everything. Sometimes also the application can't establish and I have got following error:
-----lwIP TCP echo server ------
TCP packets sent to port 6001 will be echoed back
Board IP: 192.168.1.10
Netmask : 255.255.255.0
Gateway : 192.168.1.1
auto-negotiated link speed: 100
Unable to bind to port 7: err = -8
but ML605 still response for a ping... It just I can't connect to a board. After That I must re-run application for a many many time...
I am newbie in embedded processor. Many thanks for help!

Hey dude, i am doing the exact on ML410 and having same problem as you. I can ping the host PC but cannot connect through hyperterminal/teraterm. I am using the basic lwip echo server. Did turning off firewall solved your problem? Also I cannot type on my hyperterminal window. Is it because I am unable to connect to my host PC? Because I can type on the screen while using COM1.

The error message u got 'Unable to bind to port 7: err = -8', says your port is already in use . Stop using this port 7 for any other application and try with your echo server.
