USB Interface Adapter EVM problem

I would start by using the USB interface adapter with the Fusion Digital Power Designer to try to connect with the UCD9240 controllers on the SP605.

The script you are attempting to use with the Manufacturing GUI appears to have been written with configuration and test functions (GPIB  interface and test equipment which I suspect that you do not have at your location) and is used in Xilinx's fabrication process.

If you are able to connect with the Fusion GUI then you can use the Import Project selection from the File dropdown to load another configuration.  The project files have the *.XML extension.

Care should be exercised when modifying the configuratiion file on Xilinx's board to avoid applying a voltage which is not compatible with the load hardware.

The latest release of the Fusion Digital Power Designer is a free download and can be found here:

Thanks a lot for your reply Brad. 

The thing is, I've tried using Digital Fusion Designer (online mode), but it can't detect any devices. I guess it should detect it automatically (with default parameters),shouldn't it? 
During the detection I applied power to SP605 board and it seemed that UCD9240 are getting warm after few minutes (so I guess it's a good sign), but despite that Digital Fusion Designer can't detect any device. So I think that maybe some detection parameters (frequency, etc.) are needed to be changed or UCD9240 chips are dead, but that would somehow be  strange, that two chips gone down after short-circuit (if such had occured)...

Maybe you have any suggestions what i should try next?

I'll assume you are powering the SP605 board prior to running the Fusion GUI.

Check the Device Scan Mode:

Open the Fusion GUI Offline by either opening an existing project or start a new project.  Click the Preferences selection from the File dropdown.  Click the Configure Device Scan Mode and Adresses button.  Make sure all addresses are set to DEVICE_ID, clicking the DEVICE_ID button at the top of the window will set all addresses to this if they aren't set correctly.

If this doesn't solve the problem then I want you to try the following:

Navigate to Start --> All Programs --> Texas Instruments Fusion Digital Power Designer --> Device GUIs --> UCD3xxx Device GUI

Click the DEVICE_ID link in the Tools section of the window (it says Scan for Device in Program Mode: right next to the link)

If the log indicates that No devices found, then click the Scan Device in ROM Mode link, found on the first line of the Tools section.

Let me know if this returns a positive result.

Thank you for your cooperation and such a comprehensive reply.

Yes, Fusion GUI is started after powering SP605 board.

I'll post the results here in less than 24 hours. 

I've tried both of your suggestions, but unfortunately still no positive results..

Here is what I get:

The only LED that shines when power is supplied is DS14 (which just indicates that 12V Power is on).

I measured voltage a few weeks ago and unfortunately I don't have a chance to check circuits again at the moment. At that time (two weeks ago) I thought that UCD9240 are powered by 12V:

so I didn't check 3.3V rails...I guess I should have analyzed schematics properly :) 

As far as I can remember 12V reaches UCD9240...(if I'm not wrong..)

I also checked other devices' pins which are (seemingly) powered by UCD9240 and voltage was very low...about 0,2-0,5 V...

I'll add more info after investigating SP605.. I guess I can already prepare to send my SP605 that thet would replace UCDs :|

Thanks again for your cooperation :)

Merry Christmas! 

The 12V feeds a BJT located near the UCD9240, the 3V3 bias is regulated off of the 12V by the UCD9240 controlling the base of the transistor.

The first UCD9240 of the SP605 board was dead :)

Thanks for your comprehensive help Brad!
