6. Turn on the Program/Configure option for the added file.
7. Click Start to download the selected configuration file to the FPGA. Configuration
is complete when the progress bar reaches 100%. The CONF DONE LED (D14)
and the four user LEDs (D7-D10) illuminate indicating that the flash device is
ready for programming.
8. On the Windows Start menu, click All Programs > Altera > Nios II EDS > Nios II
Command Shell .
9. In the Nios II command shell, navigate to the
dir>\kits\arriaIIGX_2agx125_fpga\factory_recovery directory (or to the
directory of the .flash files you created in
“Creating Flash Files Using the Nios II
EDS” on page A–2 ) and type the following Nios II EDS command:
nios2-flash-programmer --base=0x08000000 _hw.flash
r
10. After programming completes, if you have a software file to program, type the
following Nios II EDS command:
nios2-flash-programmer --base=0x08000000 _sw.flash

For boards with dual-die CFI flash devices, use --base=0x0A000000. For
more information, refer to the Board Revision History appendix of the
Arria II GX FPGA Development Board Reference Manual .
11. Set the USER_LOAD switch (SW4.4) to the on position and power cycle the board
to load and run the new user design .
Programming the board is now complete.

Restoring the Flash Device to the Factory Settings
This section describes how to restore the original factory contents to the flash memory
device on the FPGA development board. Make sure you have the Nios II EDS
installed, and perform the following instructions:
1. Set the board switches to the factory default settings described in “Factory Default
Switch Settings” on page 4–2 .
2. Launch the Quartus II Programmer to configure the FPGA with a .sof capable of
flash programming. Refer to “Configuring the FPGA Using the Quartus II
Programmer” on page 6–20 for more information.
