Hi @Susu ,

I have designed a custom board using STM32G431 and TCPP03, am able to see the debug traces in CubeMonUCPD. But unable to get the GUI interface and board is not detected. I have enabled the GUI interface in cubemx ,still not working.Can you please help! 

 

Thanks in advance!

    You can refer to this wiki ,Chapter 9.1.

    But I have also tried to use a UART to USB converter (like CH340) to visualize debug trace, but get the same result as yours. It seems like that only using the onboard ST-LINK can work effectively.

    So, currently you are using ST-link with your custom board to access GUI_INTERFACE?

    Yep, using the Nucleo onboard ST-LINK.

    Hi @RJain.1 

    Only STMicroelectronics COM ports are authorized.

    In your specific case of a USB UART converter that appears as a COM port to the PC, it is excluded from the list of potential COM ports by the STM32CubeMonitor-UCPD. Otherwise, any competitor could use our tool.

    Hi @FBL , 

    The explicit contract has been completed correctly, but it is unable to select a source PDO (the Selected SRC PDO is empty, as shown in the image by the arrow).

     

    PFA, trace, and screenshot.
