TPS65994AD: Configuring it as DRP

Hello,

The GUI tool has been updated to this, however, the user guide has not been updated.  I also could not find the sink.bin file.  I would recommend the following:

Project-> New -> TPS65987DDH -> TIDA-050014 Sink Board

And I could not switch to FDTI either...

If you are connecting to the TPS65994 EVM, then please use the correct GUI and follow the steps as described here using the TIVA interface. 

The binary of the 988 family is not compatible with the TPS65994.  You will need to generate the sink configuration using the appropriate GUI tool.  As indicated on the product page you can request access to the GUI tool here.

Hi,

So I used the setting, Project-> New -> TPS65987DDH -> TIDA-050014 Sink Board, as you wrote.

But then how do I flash it to the boards?

According to the guide, I should flash the source board then the sink board, right?

This situation leads us back to the question.

Which interface should I use? FDTI or TIVA?

For PD duo, I think there is only FDTI, right?

And for 65994, TIVA could be an option.

But I am having trouble connecting to these two devices.

I could not use the FDTI on PD duo, TIVA on 65994 either.

This is what I am struggling with now.

And yes, I have used two GUIs.

TPS65981_2_6_7_8 Application Customization 6.1.4 for PD duo.

TPS65993_4 Application Customization 6.4.32 for TPS65994QFNEVM.

Please let me know if the GUIs are not correct.

The Power DUO uses the FTDI and the 65994 EVM uses a TIVA.

When you plug into the USB make sure you can see the com port enumerate.

Check the signals on the J2 header.  If this does not work you could use an Aarvark to program the devices instead using this header.

Sounds like you need to debug if the FTDI is bad.

Yes. Those are correct.  I have looked again at the 6.1.4 gui and you can find the binaries here:

C:\Program Files\Texas Instruments\TPS65981_2_6_7_8 Application Customization 6.1.4\tps6598x-application-customization\recovery

tps65987_power_duo_mode_SINK_evm_flash_image.bin

tps65987_power_duo_mode_SOURCE_evm_flash_image.bin

No, there is no additional COM port coming up when I plugged the board.

From what I saw in other threads, there should be like 4 additional serial port under USB devices, right?

And it seemed like I am not the first one having this FDTI connection error.

Could you please share your experience of debugging it with me?

Regards,

Alex

Thanks for finding the bin files.

But I still need to find a way to program it.
