Updating an AD9552 eval board to be compatible with the 64-bit USB drivers
================================================================================
Updated May 13th, 2014.


The following steps re-flash AD9552 EEPROM for the USB controller to make 
it compatible with 64-bit USB drivers. This utility is also useful if the 
USB (CR4) LED fails to blink when the evaluation board is connected 
to the computer. 

1.	Download and install the USBEvBdProgrammerSetup.zip file.

2.	Before applying power, pull the JMP1 (USB EEPROM ENABLE) jumper. 

3.	Apply power to the board and connect the USB cable. 
	This puts the Cypress chip in its default mode.
	The USB LED (CR4) will not blink. 
	
4.	Replace the JMP1 jumper. This re-establishes the connection between the 
	EEPROM and Cypress USB controller chip.

5.	Run the Evaluation Board Programmer software. 

6.	At the top of the window, the user should see "Cyusb-1" under 
	"Select USB Device to Program."

6a.	If "No Boards Found" is displayed, open a file called "DriverGuide.mht" 
	located in the following directory for instructions on how to associate 
	an unknown evaluation board with ADI's software:
	C:\Program Files (x86)\Analog Devices\USB Eval Board Programmer


7.	Select "AD9551/52 Eval Board (32/64-bit)" for "Select Evaluation board to Identify" 


8.	Click "Program EEPROM". The software should indicate successful programming.


9.	Disconnect the USB cable and power cycle the board. 


10.	Connect the USB cable. The USB LED (CR4) should blink after 
	Windows completes the loading of the USB drivers. 
	If Windows prompts you the location of the USB drivers, 
	select "Install from the default location."


11.	If the evalution software is working correctly identifies the 
	evaluation board. the lower left corner of the evaluation software 
	main window should indicate "CYUSB-1" or CYUSB-2"

	If the evaluation software fails to identify the correct 
	AD9552 evaluation board, ensure that there are jumpers 
	installed on the evaluation board as follows:

	JMP3: Installed across center pin and "PC"

	JMP1: Installed

	Jumper Block P2: All installed.

	Switch Bank S1, S2, S3, S4: all high
