Hello @Lmatt.1
have a look at this wiki, il will show how to use the UM2552 (stack user manual). The UCPD monitor tool is very convenient to trigger some actions, and see what's going on the protocol side.
You can also have a look at this wiki to see how to do sink application step by step.

Hello @Nicolas P. ,
Right now, the 100W sink system works.
But I met a problem that only one orientation (USB Type C) works normally, I mean output 20V(100W). There are a battery pack exists in my system. If removed this battery pack, two orientation all works fine.
It seems if there are a battery pack, the MCU power on all the time, The PD protocol only be running successful for CC1 or CC2, can't running succeed on another orientation when unplug and changed the orientations. If there are a battery the state was fixed( CC line can't be released all the time only if removed the battery pack).
What's the reason? Could you please give me some advice?
Thank you very much,
Matt

Hello @Lmatt.11 . I saw that you opened the same topic on an another post : https://community.st.com/t5/stm32-mcus-products/when-to-enable-the-dead-battery-mode-for-ucpd-there-are-a/m-p/602597#M226007
I propose to close this one, not to duplicate answers. Do you agree ?

@Alfredo ,
Do you met only one orientation of USB type C can be worked when there is a battery pack in the system?
If no battery, both orientations works fine, out put 20V/5A, or other PDO?
Thanks,
Matt
