Appendix B. Restoring the
Factory Configuration
Introduction Your Nios development board can always be restored to its factory-
programmed configuration. To restore the factory configuration, you
must reprogram the flash memory on the board and you must reprogram
the EPM7128AE configuration controller device.
If you have a Nios development board, Stratix Edition, already
programmed with the first-generation Nios processor, and you want to
start using the Nios II processor, first you must update your development
board using these instructions.
The files required for this operation are included in the Nios II
development kit’s <Nios II kit path>/examples/factory_recovery
directory.
Reprogramming
the Flash
Memory To reprogram the Flash memory on the development board, perform the
following steps:
1. Open a Nios II SDK Shell by choosing Windows Start > Programs >
Altera > Nios II Development Kit
<installed version> > Nios II SDK
Shell .
2. From the example directory, change to the factory_recovery
directory for your development kit.
cd factory_recovery/< development board>
where <development board> is either the niosII_stratix_1s10 or
niosII_stratix_1s10_ES
directory.
ES development boards have Stratix EP1S10 devices whose part
numbers end with “ES”.
3. Run the flash-restoration script:
./restore_my_flash
Follow the script's instructions.
