TPS65987D: Errors with EVM and GUI

Hello Darren,

Can you answer the questions below to isolate the FTDI related issue?

1. Can you confirm that FTDI is enumerating correctly in your device list?
2. Did you try a clean and reinstall of the FTDI drivers?
3. Was this EVM working before / with a different system?

I will look into the other issue related to Importing of settings and share an update shortly.

In the meanwhile, do you have an Aardvark that you can use to work with?

Regards,
Kedar

Hi Kedar,

Here are the responses to your questions.

1. Can you confirm that FTDI is enumerating correctly in your device list?

Yes it is enumerating as a Quad RS232-HS

2. Did you try a clean and reinstall of the FTDI drivers?              

Yes yesterday afternoon based on discussion with Darren,  installed http://www.ti.com/tool/TPS6598X-CONFIG.

This install included re-installing the FTDI driver. Problem didn’t change.

3. Was this EVM working before / with a different system?

                No, new out of the box. I have two of them they do the same thing

They do not have an Aardvark.  I'll point them to the totalphase site in case they want to buy one.

What do you think about testing with that TPS6598X-CONFIG?  Should they uninstall that now?

Thanks,

Darren

Hi Darren,

Could you please try the application on a different machine? We have seen issues with the FTDI drivers on some Windows environments.

Please share your observations.

Kedar,

 Which application do you recommend they install first on the other machine.

Thanks,

Darren

Hi Darren,

Sorry for the delay in response. Since this is a Windows environment related issue, I cannot comment on any other application dependency since the Configuration tool runs stand alone.

Hi Daren and all,

We have had same problems as you reported and today we have found a solution for WIn 10 computer:

- uninstall TI SW for TPS65987DDH

- uninstall drier for FT4232 chip

- go to FTDI WEB, look for drivers for FT4232 and the table listing all Windows drivers. First line shows WIN10 driver 2.12.28 and on this line on last column is explanation "Available as a setup executable". 

-click on "setup executable" and download file CDM21228_setup.zip

- Install FT driver from this file, do not connect TPS65987 EVB or anything else to computer

- Now install again TI SW but remove all hooks from FTDriver and other drivers in the window on the beginning of installation, install just SW

- Try again, now I2C will show proper port and board will work

Best regards,

Branislav

Hi Branislav,

Thank you very much for sharing this.  I really appreciate the level of detail you provided.

I'll pass this information along, and I'm hoping to report back here with the results.

Thanks again,

Darren

Thanks Branislav.

Darren,
Can you confirm if Branislav's steps helped resolve the issue?

Hi Kedar,

The customer had to put this aside and won't be able to test and confirm for 2 or 3 weeks.

Thanks,

Darren

Hi Kedar; Darren and all,

I have posted a solution how to make TPS65987EVM working with TI SW, the problem was in FT4232 driver installation. Since last 4 days we use EVM and we still have some problems. Sometimes it behaves different on WIN10 and WIN8 machine. One example is that SW suddenly can't find I2C on address 38 but on 20. The solution we found is to restart SW. Other persistent problem is that write to EEPROM does not work and returns error. Possibly it is also related to SPI driver for FT4232.

EVB board we have is with TPS65876DDH chip. It is very complicated to found the difference between DDH, DDJ, D and other variants of the chip.

Best regards,

Branislav
