Creating Flash
files for Remote
System update The image required for remote system update consists of a Flash image
for FPGA configuration and if your system has a software application
then it consist of a Flash image for the software application. To create the
flash files you must have the Nios II EDS and Quartus II FPGA design
software installed on your PC.
■ A hardware SRAM object file (*.SOF) must have the cpu reset
address configured from the Flash device at offset 0x0.
■ Create the software Executable link format file (ELF) in the standard
fashion.
■ On your host PC, launch a Nios II Command Shell from Start ->
Programs -> Altera -> Nios II <
version #> EDS -> Nios II Command
Shell
■ From the command shell navigate to where your SOF file is located
and create your hardware Flash image using the following
command:
sof2flash --activeparallel --input=”your SOF.sof” -
-output=”your SOF.flash” --
offset=”RECONFIG_ADDRESS”
■ From the command shell navigate to where your ELF file is located
and create your software Flash image using the following command:
elf2flash --base=0x04000000 --end=0x04FFFFFF --
reset=0x04240000 --input=”your ELF.efl” --
output=”your FLASH.flash” --
