    USB-C Function Test fail

    mamic_3349671

      Hi,
      we are working with CCG5 (CYPD5225-96BZXI) and SDK 3.3.0.
      Our board is currently under certification tests and results that USB-C Function Test fail on:

      TD 4.6.5 Try.SRC DRP Connect Sink Test

      PD 2.0 5A Active Cable -> For a PUT_R, the PUT must provide Rp on both CCS.
      PD 3.0 5A Active Cable -> The PUT connects the SS pairs after 80 ms.


      Looking at https://www.usb.org/sites/default/files/USB_Type_C_Functional_Test_Specification_2018_05_28.pdf, we found that TD 4.6.5 test fails on steps D.2.c.i and D.6.a.i.
      We haven't found any connection between CCG5 firmware configuration or external HW layout connected to CCG5 and actions involved in test procedure, but seems that all is managed by CCG5 firmware internal routine.

       

      Did you receive any feedback about this issue?
      Is there any aspects on firmware configuration or external HW layout connected to CCG5 to focus on?

       

      Best regards.
