Connect the DC power-supply to connector J26, as shown in
. Select the appropriate power cord for your
geographic region. Connect one end to the DC power supply and
the other end to a power outlet.
Verifying Correct Operation of the Nios Development Board
You will see activity on the board after applying power. As soon as you
apply power to the Nios development board, the Altera FPGA is
configured with a Nios II processor hardware reference design. Once the
FPGA configuration is complete, the Nios II processor in the FPGA wakes
up, initializes itself with boot code from flash memory, and displays
“Nios II” on the LCD for 10 seconds, followed by scrolling instructions
for a web server demo. You can connect the board to an Ethernet network
and view web pages served from the web server reference design.
Verify the following indicators of a properly functioning Nios
development board:
■
The power LED (LED5) is on. LED5 is located under the Altera logo
near the top-right corner of the board.
■
The LED labeled “Safe” or “Factory” is on.
■
The two 7-segment LEDs are active, displaying a spinning pattern.
■
The LEDs D0 – D7 are active, displaying a bouncing pattern.
■
The LCD displays “Nios II”.

The LCD screen might not function if a CompactFlash card is
seated in the CompactFlash socket.
If you are not the first user of your Nios development board, the board
might no longer contain the original factory image programmed in flash
memory. In this case, you will not see the same indicators noted above.
The LED labeled User might be on or flashing, indicating that the
development board is programmed with another designer’s user image.

If you want to reprogram your board to its factory default condition,
refer to the appropriate Nios Development Board Reference Manual.
If this is the first time you are applying power to the Nios development
board and you do not see the indicators above, check all the connections
and make sure that power is supplied to the board properly. For further
