Ready-to-Run Applications
What’s in a
Ready-to-Run
Application?
This section describes some details about the 3 components that make up
a ready-to-run Application,
■
All loadable applications on the SD Card must be located in a top-
level directory named altera_3C120_apps.
■
Under the altera_3C120_apps directory, each application is located in
its own subdirectory. The name of that subdirectory is important
because the application selector utility uses that name as the title of
the application when displaying it in the main menu. The name of
the subdirectory is the title that will be displayed for your
application in the menu. The subdirectory names can be anything so
long as they adhere to the FAT file system long file name rules.
Spaces are permitted.
■
The SD Card must be formatted with the FAT 16 file system, and can
be any capacity up to 2GB. Long file names are supported.
■
Each loadable application consists of two flash files, and an optional
text file, all stored on an SD Card.

The FLASH file that contains the software portion of
the application. It is derived from an .ELF file as
described in the section of this document titled

This flash file can be named anything supported by
the FAT16 file system, the only restriction being that
the name must end with _sw.flash
<filename>_hw.flash
Flash file represents the hardware portion of the
application. It is derived from a .SOF file as

name must end with _hw.flash
Info.txt
The optional info.txt file contains additional
information about the application. In the application
selector utility, touching the Show Info button while
