    Failed to enter VDM mode process




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


      (1) In the initial state, I am a Power sink.

      (2) Then, I actively initiated PR_Swap to become a Power source.

      (3) Finally, I call dpm_start(TYPEC_PORT_0_IDX) to get back to the initial state.

      (4) After CC re-communicates, sometimes the enter VDM mode process fails.



      In the Fail case, Enter VDM mode process failed.


      Pass case:

      Fail case:



      1. How to avoid this happening?

      2. When I enter this state, where can I read the information?



      Thank you.
