    CYPD3125 + PS8740B report Error

    Mosh_3277376

      现在ccg3与MUX芯片已通过iic能够通讯,但当与电脑相连时,会依次报告  aa   84  9a(Hard Reset Sent to Port Partner)  b8(Hardware Error )  9a  b8  9a  b8  9d  的事件,具体寄存器值见附件log.txt

      抓取MUX与ccg3的IIC波形,为:20 00 20,只有一帧数据,请帮忙查找一下ccg3中是什么情况下会出现这种情况,多谢。

          Hi Moon,

           

          Could you please kindly take a look the MUX on your design supporting UFP or DFP mode? Please kindly notice that CY4531 is supporting DFP role since the board assembling PS8740B.

           

          Mwanwhile, please kindly share the CC log of this test case to us.

           

          Thank you for contacting us.

           

          Best Regards,

          Lisa
