DisplayPort Alternate Mode command flow did not finish running.

Dear,

I made a dock and used the CYPD4236-40LQXI_dock sample code.

Stopped in step 8 when entering DisplayPort Alternate Mode.

I can't see the "DP_Status_update" sent from my laptop.

How to solve this error?

This is PASS case.

This is fail case.

Dear Lisa,

But this source side is a laptop, and I can't control it.

Is there any way to avoid it sending this message?

Best Regards,

Hi Manu,

Could you please kindly use a laptop which was mass production on the market? And test it again?

Best Regards,
