Hi 

Please check the project file to see what the problem is.

3527.not working .pjt 7750.type c display port alternative mode.pdf

The following reference binary works. Ask if you can convert the reference binary into a project

 Thank you very much for your help.

Hi Kim,

Please ensure you are using the latest version of the Application Customization Tool. When selecting a project file, you will have to answer many questions related to what you want your system to support. Once the template is created, you need to double check the GPIO configurations to make sure they match your hardware.

Thank you,
Eric

Hi Eric

I am using version 5.13 of the Application customization tool.
I was not wrong with gpio

I have selected Enable Display Port SVID, Enable Display Port Mode1 in the application customization tool configuration mode, but it does not fit into the display port alternative.

Hi Eric

I checked the display port alternate native mode behavior with the UFP reference design.

How can I charge the display port alternate native mode and the phone at the same time, because the phone is not charging?

Hi Kim,

You can modify the Port Control Register (0x29) to do a power role swap to source. You would need to check "initiate swap to source". This would allow your device to do a power role swap to source if the phone supports PD.

Thanks,
Eric
