USB PD Dead Battery Issue

[xufl]

• My STM32H533VE works as PD Sink.
• We connected CC1/CC2 with DBCC1/DBCC2 (as AN5225), STM32 cannot power up with a USB PD adapter. The adapter supplies power for ~20ms then stops the supplying.
• If I remove the long time initialization code (LSE initialization), system can boot up and USB PD works fine (PDO can switch).

Is this normal? if yes, I may move the LSE initialization later.

Hi @xufl 

I have found your issue is already under investigation internally 224687 and you can reach your local FAE for further updates.

Hi FBL,

Is there any progress on your investigation? Have you reproduce this issue? FAE does not get any update. And I need to report the latest status to cutstomer and management.

Best Regards.
