Altera Embedded Systems Development Kit, Cyclone III Edition July 2010
Rebuilding the Application Selector from Source Files
Boot Code
The first portion of the factory recovery image is the application boot
code, located at flash offset 0x0. For details on the boot code refer to
Chapter 8, Application Selector Details.
Building the boot code produces a file named
app_selector_boot_code.srec.
This file can be directly programmed to flash using nios2-flash-
programmer in the Nios II command shell.
Hardware Image Catalog
The hardware image catalog section of flash is located at offset 0x2000000.
This section holds the locations of the currently cached hardware images
Catalog in flash. Any time a factory recovery is performed, this section of
flash should be erased to ensure no stale catalog entries exist. To erase this
section of flash, enter the command:
1. Connect the board to your local PC using the provided USB cable
2. Launch a Nios II Command Shell
3. In the Nios II Command Shell, navigate to location
<install_dir>factory_recovery/flash_contents and type nios2-
configure-sof
This will configure the board with a safe FPGA image
4. In the Nios II Command Shell type
nios2-flash-programmer --base=0x10000000 –-erase
