Using the Nios II Evaluation Kit
See “Using Nios II Linux” on page 13 for more information about the pre-
loaded version of Nios II Linux on your Nios II evaluation board.
You now have successfully set up your evaluation board. You now have
the choice to continue to “Using Nios II Linux” on page 13 to learn about
the example Linux kernel that is programmed into the flash on your
board, or you may skip ahead to “Starting the Nios II Development
Tools” on page 16 to begin learning how to develop your own software
for the Nios II processor.
Instructions for Restoring the Factory Configuration
The Nios II evaluation board can always be restored to its factory-
programmed configuration. To restore the factory configuration, you
must reprogram both the Cyclone FPGA on the embedded processor
module and the flash memory on the embedded processor module.
To reprogram the embedded processor module, perform the following
steps:
1. On the Windows Start menu, click Programs, Altera, Nios II
Evaluation Kit <installed version>, Nios II SDK Shell to open a
Nios II SDK Shell.
2. From the examples directory, change to the factory_recovery
directory for your development kit by typing the following at the
shell prompt:
cd factory_recovery/niosII_cyclone_1c12_eval
r
3. Run the flash-restoration script:
./restore_my_flash
r
4. Follow the script's instructions.
