The simple_socket_server hangs on our ep2c35 develop board with lan9111, as in the attachments. The application program includes ucosii RTOS and lwip, uneable DHCP, using 192.168.1.128 as its static ip .I have get success on quartusii 5.0/niosii 5.0, but when I update to quartusii 6.0/niosii 6.0, it hangs . I don't there needs some change on simple_socket_server_syslib setting.
when I run the simple_socket_server on ep2c35 development board , the jtag port print as follow.I don't how to deal with it.nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) Simple Socket Server starting up Your Ethernet MAC address is 01:02:03:04:05:06 [lwIP]: See STDERR for expanded diagnosis translation.
