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 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 6–27

for more information.

3. Click Add File and select

dir>\kits\stratixIVGX_4sgx230_av\factory_recovery\s4gx230_av_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 (D5) and
the eight lower user LEDs (D16-D23) 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

dir>\kits\stratixIVGX_4sgx230_av\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 (SW1) off then

on.

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

dir>\kits\stratixIVGX_4sgx230_av\factory_recovery\s4gx230_av_bup.sof.

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

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

is complete when the progress bar reaches 100%. The CONF DONE LED (D5) and
the eight lower user LEDs (D16-D23) illuminate indicating the flash memory
device is now restored with the factory contents.

12. Cycle the POWER switch (SW1) off then on to load and run the restored factory

design.

13. The restore script cannot restore the board’s MAC address automatically. In the

Nios II command shell, type the following Nios II EDS command:
