11. Set the PGM CONFIG SELECT rotary switch (SW5) to the 1 position and power

cycle the board, or press the RESET CONFIGn button (S1) to load and run the user

hardware 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 For boards with dual-die CFI flash devices, use <install

dir>\kits\stratixIVE_4se530_fpga\factory_recovery\dual_die_flash directory. For

more information, refer to the Board Revision History appendix of the Stratix IV E

FPGA Development Board Reference Manual.

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 6–24 for more information.

3. Click Add File and select <install

dir>\kits\stratixIVE_4se530_fpga\factory_recovery\s4e530_fpga_bup.sof.

4. Turn on the Program/Configure option for the added file.

5. Click Start to download the selected configuration file to the FPGA. Configuration

is complete when the progress bar reaches 100%. The CONF DONE LED (D22)

and the eight user LEDs (D23-D30) illuminate indicating that the flash device is

ready for programming.

6. On the Windows Start menu, click All Programs > Altera > Nios II EDS > Nios II

Command Shell.

7. In the Nios II command shell, navigate to the <install

dir>\kits\stratixIVE_4se530_fpga\factory_recovery directory and type the

following command to run the restore script:

./restore.sh r

Restoring the flash memory might take several minutes. Follow any instructions

that appear in the Nios II command shell.

8. After all flash programming completes, cycle the POWER switch (SW3) off then

on.

9. Using the Quartus II Programmer, click Add File and select <install

dir>\kits\stratixIVE_4se530_fpga\factory_recovery\s4e530_fpga_bup.sof.
