board. Similar examples may exist for the ADSP-BF527 EZ-KIT Lite
development board but will use only the USB host mass storage interface
to access USB flash drives.
Three examples are included. The first (HardDiskAccess) shows how to get
started with the file system service. The second (HardDiskFormat) is
somewhat more complex and demonstrates how to use the constituent
drivers away from the FSS in order to format the hard disk drive,
especially if it has never been formatted previously. The final example
(Shell_Browser) is a multi-threaded, VDK-based application demonstrat-
ing the use of the file system service within a multi-threaded,
multi-peripheral environment.

HardDiskAccess

This simple program (the Hello World of the FSS) demonstrates the basic
configuration of the file system service and its use.

Description

This example program performs the following operations:
1. Shows the characteristics of the FAT partition.
2. Creates a sub-directory on a hard disk.
3. Moves to that directory.
4. Creates a file in that directory.
5. Lists the contents of that directory.
6. Performs a checksum operation on the created file and displays the
results.
7. Removes that file.
8. Moves back to the root directory.
