Factory & User Configurations
User Configuration
The user configuration partition is 4 MB, starting at offset 0x00800000.
This section contains the FPGA configuration data for the user
configuration. Nios II development tools include documentation on how
to create your own user configuration image and program it into flash
memory.
Factory Configuration
The factory configuration partition is 4032 KB, starting at offset
0x00C00000. This section contains the FPGA configuration data for the
factory configuration. The Nios II processor in the factory configuration
is designed to start executing code from offset 0x00000000 in the flash
memory. The Nios II development kit includes the source files for the
factory-programmed hardware and software reference designs.
Persistent Data
The persistent data partition is 64 KB, starting at offset 0x00FF0000. This
partition is for maintaining nonvolatile settings and data, such as the
MAC address and IP address for the factory-programmed web server
reference design. Persistent data is technically no different than other
application data, but it is often convenient to think of certain data as
independent from the user hardware or software.
