TPS65987EVM: Trying to connect as Charge while Host Mode

Andrew Phillips2

Part Number: TPS65987EVM

I am trying to get the TPS56987EVM configured to allow for a Samsung Galaxy 9 to charge while in host mode. The device claims to support USB PD, and I am trying to get it to be able to charge while in host mode (like a Kiosk mode). The USB PD supports this I believe, but I don't know how to configure the TPS65987EVM to test and emulate this.

Can anyone give me some help here? I can get it to charge (in fast mode) but it doesn't recognize any device I'm plugging into the board. I am using the DisplayPort Sink Board (but using the USB A port only).

Any assistance would be greatly appreciated here!

Thanks!

Hi Andy,

Are you using the latest version of the TPS6598x Application Customization tool? You should be able to select TPS65987D and load a standard UFP project for this to work. Please keep in mind that you will need to use the 10G EXPANSION EVM with the TPS65987EVM for this to work. And you would need to use the expansion board with the USB Type-B connector.

Thanks,
Eric

Thanks a ton for the quick reply....

I have tried this and couldn't seem to get it to work. The one does not recognize the keyboard (even though it does when I plug it in directly without the EVM). Please see attached picture.

I create a new project and selected the UFP project as well, flashed it, and it doesn't appear to help.

I do, though, always get a "SPI Verification Failed" so maybe that is the issue?

Attached is the image of my setup, by project as well. Anything else I can provide?

Hi Andrew,

The SPI Verification should not fail. Can you confirm that you have the barrel jack connected to the EVM when you are flashing it? I suspect that the configuration is not being loaded onto the EVM correctly.

Thank you,
Eric

I do not, I was not aware that was the case. I'm in a conference call, but will be available to try it in an hour. I'll plug the barrel in and then try the flash. Thanks a ton for the feedback, give me an hour to try it out!

That did not resolve the issue (connecting the barrel plug in). Still get the same error, I've attached the screen shot. Any other ideas?

I got it to do the SPI verify now by completely re-installing the FTDI drivers from the FTDI website and not the ones provided by the TI install. Seemed to fix my SPI Verify issue. working with the configuration now to get it to charge while a USB host, I had to play with the settings some beyond just loading the default profile as suggested but I got it to do what I want, and its working! Thanks for all the help. For future reference to anyone else, get the FTDI drivers from their website (at least that's what did it for me).
