5.4 Restoring the Factory Image

Restoring the Factory Image

This section describes some details about the operation of restoring the Application Selector factory

image.

Combining factory recovery binary files

In the factory settings, you need to program Application Selector binary files to EPCS. Before

programming, you should combine application selector software binary file and hardware binary

file together by executing the instructions below:

•

Copy both the tPad_Selector.sof and tPad_Selector.elf files into a common directory relying on

your choice. This directory is where you will convert the files

•

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

binary file using the following command commands listed below

•

Convert tPad_Selector.sof file into tPad_Selector_HW.flash file

sof2flash --epcs –input=tPad_Selector.sof --output= tPad_Selector_HW.flash

•

Convert .flash file into .bin file

nios2-elf-objcopy –I srec –O binary tPad_Selector_HW.flash tPad_Selector_HW.bin

•

From the command shell navigate to where your ELF file is located and create your software

bin image using the following command commands listed below

•

Convert tPad_Selector.elf into tPad_Selector_SW.flash

elf2flash –epcs --after=tPad_Selector_HW.flash --input=tPad_Selector.elf

--output=tPad_Selector_SW.flash

•

Convert tPad_Selector_SW.flash into tPad_Selector_SW.bin

nios2-elf-objcopy –I srec –O binary tPad_Selector_SW.flash tPad_Selector_SW.bin

•

Combine tPad_Selector_HW.bin and tPad_Selector_SW.bin using the following command

cat tPad_Selector_HW.bin tPad_Selector_SW.bin > tPad_Selector.bin

•

The generated tPad_Selector.bin is our target binary file
