Updating an AD9912 eval board to be compatible with the 64-bit USB drivers
=============================================================================
Updated November 6th, 2014.


The following steps re-flash AD9912 EEPROM for the USB controller to make 
it compatible with 64-bit USB drivers. This utility is also useful if the CR1
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 JMP2 jumper. 
	On older eval boards, it may be labeled “EEPROM ENABLE.” 

3.	Apply power to the board. (This puts the Cypress chip in its default mode.)

4.	Replace the JMP2 jumper. This re-establishes the connection between the 
	EEPROM and Cypress chip.

5.	Connect the USB cable. The CR2 LED next to the USB connector will not blink. 

6.	Run the software. 

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

7a.	If "No Boards Found" is displayed, the user should locate 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


8.	Select "AD9912 Eval Board (32/64-bit)" for "Select Evaluation board to Identify" 


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

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

11.	Connect the USB cable. The USB status LED (CR2) 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."
