TPS65987D: TPS65987D works with HD3SS460, no DisplayPort signal output

Hi TI team,

We have a project that used TPS65987 and HD3SS460 to implement DP ALT mode on the Source side. The schematic is attached.

Now the TPS65987 can be programmed by the Application tool. And the PD status works fine (5V/3A is good), and the UFP device can be detected when making a TypeC monitor plugged.  But no Displayport signal output！！！The program project file is attached.

Using the Application tool debug mode, below are some screenshot for reference.

Looking forward to your response. Thanks!

It's strange that DFP_U is connected but DP function is Disabled and HPD is always low.
