Rebuilding the
Application
Selector from
Source Files
This section describes the process of rebuilding the factory recovery
image from source files. You may wish to modify and rebuild the factory
recovery image, if you’ve modified the application selector or boot code
and would like a single recovery file which includes your modifications.
Keep in mind that any modifications you make to the application selector
or boot code, may make them incompatible with existing applications.
Each portion of the factory recovery image is described below, with
instructions on how to create it and program it to flash. The last section
here, titled
“Combining factory recovery image files” on page 11–5“
,
includes instructions for creating a single factory recovery image that you
can program into flash at any time to restore the factory configuration of
the board.
To perform the tasks illustrated in this section, you must first open a
Nios II command shell.
