4 Version:
5 September 13, 2005 - Version 2.1 - Updated to run on either the DK3400 or the
6 DK3420 by merely making a change to the #define in the upsd3400_hardware.h file
7 and then rebuilding all target files. Also, some files were renamed and the
8 disclaimers were updated.

10 Description: USB Reference Design - Flash Disk Application (read/write)
11 This reference design enumerates as a USB flash disk making use of the USB Mass
12 Storage Device Class driver. It will appear as an available drive on the system
13 and files can be read from and written to the flash memory. The flash memory used
14 for file storage is the uPSD34xx's main flash.
15
16 This reference design is intended to demonstrate USB functionality and provide
17 example code on using the USB module within the uPSD34xx.
18
19 Supported platforms:
20 DK3400, DK3420
21
22 Note:
23 It is important to modify the #define setting in upsd3400_hardware.h to match
24 the platform (target board) being used. The value of the #define is used in
25 several places to make appropriate settings for the target board and device
26 being used.
