4.5. 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 steps:

  1. Set the board switches to the factory default settings described inFactory Default Switch and Jumper Settings.
  2. Start the Intel® Quartus® Prime Programmer to configure the FPGA with a .sof capable of flash programming.For more information, refer to Configuring the FPGA Using the Intel® Quartus® Prime Programmer.
  3. Click Add File and select <install dir>\kits\cycloneVGT_5cgtfd9ef35_fpga\factory_recovery\c5gt_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 Config Done LED (D7) illuminates indicating that the flash device is ready for programming.
  6. On the Windows Start menu, click All Programs > intelFPGAxxxxx > Nios® II Command Shell.
  7. In the Nios® II command shell, navigate to the <install dir>\kits\cycloneVGT_5cgtfd9ef35_fpga\factory_recovery directory and type the following command to run the restore script:
    ./restore.sh

    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, if powered by the laptop power adapter, cycle the POWER switch (SW2) off then on. If the FPGA development board is powered by PCIe* host, cycle the host power.
  9. Using the Intel® Quartus® Prime Programmer, click Add File and select <install dir>\kits\cycloneVGT_5cgtfd9ef35_fpga\factory_recovery\c5gt_fpga_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 Config Done LED (D7) illuminates indicating the flash memory device is now restored with the factory contents.
  12. After all flash programming completes, if powered by the laptop power adapter, cycle the POWER switch (SW2) off then on. If the FPGA development board is powered by PCIe* host, cycle the host power.
  13. In the Nios® II command shell, type the following Nios® II EDS command:
    ./restore.sh
  14. Do not remove board_information and MAC address. The restore script cannot restore them. They can not be recovered if be removed.
