TPS65987D: Usage of TPS6598x Application Customization Tool with FTDI FT260 or FT232HL based USB to I2C adapter

Part Number: TPS65987D

Hello,

We are trying to use the TPS6598x Application customization tool to configure a TPS65987D mounted on a prototype board.

We don't own neither the Aardvark adapter nor the TPS65987-EVM or TPS65988-EVM (which contain a FTDI FT4232 chip)

but we own other adapters based on FTDI FT260 and FTDI FT232HL chips.

When trying to launch the software, the USB hardware seems to be detected, but an exeception is thrown:

Exception Encountered during I2C Test Read:No FTDI I2C channels (I2C_GetNumChannels) detected, exiting....

<type 'exceptions.Exception'>

Details :

Traceback (most recent call last):

File "dialogWindow.pyc", line 2807, in test_read

File "hw_interface.pyc", line 186, in hw_open

Exception

Looks like the 3 FTDI chips are incompatible with each other.

So my question is : does anybody have some experience with these chips? Is there a driver available for FT260 or FT232?

If no drivers is available, is there a chance to modify the existing one? (From the error message, I understand that it is written in Python and should be modifiable).

Thanks in advance for your answers.

    Hello,

    Unfortunately, we do not support those other FTDI chips and cannot support driver updates on that tool at this time. I would suggest using either supported adapter option (Aardvark or FTDI included with the EVMs). However, you could simply save the full flash binary image using the App Config GUI and then using another program of your preference to load that image onto the SPI Flash. You do not have to use the TPS6598x App Config GUI to load the Flash image onto the device.

    Thank you,
    Eric

    Thank you Eric,

    That's exactly how we are proceeding currently : we copy the data into another application.

    But direct connection would be helpful for tuning. So we consider buying a cheaper "FT4232H-56Q MINI MDL evaluation module"

    It contains the same FTDI chip as TI EVMs, so I excect it to be compatible with the Customization Tool. 

    Am I right?

    Hi Jean-Paul,

    We have not done any testing with that specific evaluation module. However, as you mentioned, it uses the same chip so I think it should be okay.

    Thank you,
    Eric

    OK, lets try it this way. I will give a feedback in a few days.
