5. Press the ! key to abort the DHCP process and display a prompt. If

you don't abort the DHCP process, it will fail after two minutes, and

eventually a prompt will appear.

1 The monitor's prompt is the + character. You can enter

h<Enter> at the prompt for a complete list of supported

commands.

6. At the prompt, type xip:<safe IP address><Enter>

The xip command saves the IP address in flash memory. In general,

you only need to assign an IP address to your board once. However,

you can change it at any time by issuing another xip command. You

can also use the commands xsubnet and xgateway to assign

subnet and gateway addresses, but setting these addresses is not

usually necessary.

7. Type xdhcp:off<Enter> to disable the board from attempting to

obtain the IP address using DHCP in the future. (You can re-enable

DHCP later, using the xdhcp:on command.)

8. Type CTRL+C to terminate the JTAG terminal session and

disconnect from the monitor program, then close the Nios II

command shell.

9. Press the SW8 button labeled CPU Reset to reboot the Nios II

processor and start the web server using the new IP address. The

LCD screen displays the static IP address assigned to the board,

along with other status messages.

The web server is now ready to display pages using the IP address you

assigned. See “Browsing to Your Board” on page B–5 to continue.

Point–to–Point Connections

All boards are factory programmed with a default IP address of 10.0.0.51

stored in flash memory. The 10.0.0.x subnet is conventionally reserved for

development, test, and prototyping. If DHCP fails or is aborted, the board

uses this static IP address. The LCD screen displays status messages to

indicate when the web server starts running using the default IP address.

Your host computer and the development board are the only two devices

connected to this simple point-to-point network. For most host operating

systems, it is necessary to assign your host computer an IP address on the

same subnet as the board. For example, the address 10.0.0.1 will work

fine. Any address in the 10.0.0.x subnet will work, and there is no

possibility of conflicting with another device on the network. After
