Part Number: TUSB1146EVM
Other Parts Discussed in Thread: TUSB1046EVM,

Would it be possible to receive the "Application Customization Tool" project file and binary image for the TUSB1146EVM and TUSB1046EVM development boards? Trying to recreate EVM on a custom board but having some issues.

Thank you,

Thank you for the files but I still seem to be having the same issue.

Whenever I plug in a displayport to USB C cable the DFP enabled is always reading as "DP Functionality Disabled". Is there a connection that isn't being made?

We are using a TPS65987DDH to control a TUSB1046 ALT mode redriver in GPIO mode. The GPIO's seem to be getting the right values but the display never comes out.

Version below.

Hey Arian,

I got the default projects from David, and took a look at the project file.

Could you try enabling the DisplayPort Mode Auto Entry Allowed bit in the DisplayPort Capabilities register?

Could you also obtain a PD log of the transaction and share it?

Thanks and Regards,

Chris

Chris,

We were able to solve the issue. Turned out to be an incorrect connection. The displayport interface on the device we were connecting to needed an inverted HotPlug signal.

Thanks,
