i have an ML605 that is damaged, (already comment it), i dont measure any voltage at the VCCaux(U91), VCC2.5(U43) and VCC1v, (U42). i can also not see any PWM signals to any of those regulators. I took the regulators of and apply the required voltage leves with an extern power supply, the FPGA is working, and configurable.
I change the regulatos for new ones, but there are not voltage at the outputs nor PWM signals commign from U24 (ucd9240). I think the U24 is damaged or unconfigured. What could i do?
-Check the UCD9240 configuration with the PMBus adapter?
-Replace the UCD9240 and configure it with the PMBus adapter?
- or could i adquire a Factory-programed UCD9240 for the ML605 board?
I'd apreciate any help,

Suggestion: You would attract more interest in your thread if you posted links to the ML605 schematics and the ucd9240 datasheet.
Instead of requiring each reader to individually search for these docs, you should post the links and make it easier for everyone else.
Just a suggestion...

Ed Mcgettigan (mcgett) is probably the foremost authority on these TI power-supply modules, as used on Xilinx boards.

-clock are workings, IOs as well.
-I let the other 2 regulators on board, 3.3 and 1.5.
- VTT regulator is working aswell
-I didnt find any clear anormalities in the FPGA functionalities
How could I contact Ed Mcgettigan?

I had to check on a couple of items as we aren't publishing the programming information for the UCD9240 currently on the ML605 page.
There are two things that you need to do:
1) Buy a TI USB GPIO cable for PMBUS programming. The ML605 included a flyer for a discount on the cable
2) Contact Xilinx Support for additional information on the programming steps and the programming file
If you have any issues after opening a WebCase with support please let me know and I will assist as this isn't an common problem.

Hi Mcgett: I have open a webcase, but nobody answer this question or contact me to provide me the information on the programming steps and the programming file. Could you help me to check it ?

When you file a case on the weekend it will take a bit longer for support to get back to you.

we too have a similar status and observations with the ML605 board.
The powergood LED (DS2) is off and the powergood outputs from (U25) UCD9240 power controller is low. The VCC1V5 is at 0.05V and hence the DDR3PWR led (DS29) too is off.
The BIST and all programs loaded on the board fails to run, but the FPGA is configurable through the JTAG (since the U24 power controller feeding the FPGA power is fine, i guess) and the DONE pin goes high.
please advise how to isolate the defective component. do you have any diagnostic code to check the status of the power controllers? The only interface possible is the direct PMBUS access through FPGA .

If you think that the problem is due to the TI power controller being corrupted then step 1 is to purchase a TI USB programming cable. The ML605 was shipped with a discount coupon: http://www.ti.com/tool/usb-to-gpio The webcase that you opened should provide you with the necessary XML files to use with the TI Fusion Digital Power Designer software http://www.ti.com/tool/fusion_digital_power_designer to reprogram the controller to the original factory conditions.
If you think that the problem is due to a bad component on the board then you will need to determine the fault location. Starting with a measurement of every power supply on the board is a good first step.

I have the same problem, but with SP605. I'm reprogram ucd9240 (U26). VCC2V5_FPGA 2.5V, VCCAUX 2.5V now working, but VCCIN_FPGA 1.2V not working.. webcase registered as 894076. Can any one send me XML files to use with the TI Fusion Digital Power Designer software for programing ucd9240(U26) on SP605 board.

19840914, The WTS engineer who will handle your Webcase can provide the XML files to you.
Looking at the case notes, it appears this has now happened and you should have received the XML files.
