CoolRunner-II Starter Kit - How do I reflash the ATMEL USB controller on this board?

Description

I have experienced problems with USB communication with my CoolRunner-II CPLD Starter Kit. How can Ireload the code for theATMEL USB controller?

Solution

The CoolRunner-II CPLD Starter Kit uses the Atmel AT90USB162 USB controller. If problems with USB communication are suspected, then the code for this controller can be reloaded.

To reload this code, the AVR Programmer utility needs to be downloaded from the Digilent website:
http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,66,67&Prod=AVR-SOFTWARE

A JTAG-USB cable is then used to program the board with the files:http://www.digilentinc.com/Products/Detail.cfm?Prod=JTAG-USB

While this is a Digilent Development Board, the necessary files are available from Xilinx Technical Support. Please open a Webcase, quoting this Xilinx Answer numberto receive these files:http://www.xilinx.com/support/clearexpress/websupport.htm


Note:
This firmware is not compatible with the latest Digilent Adept software. The software provided on the CD shipped with the CoolRunner-II CPLD Starter Kitmust be used.

The CoolRunner-II CPLD Starter Kit is a mature product and is subject to obsolescence in accordance with XCN11027.
