Restoring the
Original Flash
Image
(Application
Selector) The Altera Embedded Systems Development Kit, Cyclone III edition is
programmed from the factory to configure the FPGA from flash to the
application selector. In the course of your development you may need to
replace the factory image with your own flash image. To restore the
original Flash contents of the Factory Image (i.e. the application selector)
perform the following steps:
1. Make sure you have:
a. A PC with Altera Embedded Systems Development Kit,
Quartus II
<version 8.1 or later> FPGA design software and
Nios II EDS <version 8.1 or later>
b. A USB cable
2. Connect your board to the PC by connecting a USB cable from USB
connector (J3) on your board to a USB port on your PC.
3. Launch the Quartus II Programmer and click Auto Detect. The
EP3C120F784 device should be detected.
