USBPD GUI interface not working

[RJain.1]

Hi,

I have designed a custom board using STM32G431CB and TCPP03. I am trying to make as a sink device. I followed this video : https://youtu.be/cbdFHmMOMwk?si=GqcDTJeDxTsrFDiG

I have successfully generated and compiled the code. Also, i enabled the GUI interface and TRACE. I am able to get the trace messages in STM32CubeMonUCPD. But unable to see the GUI interface board port, I tried refreshing it several times but no luck . 

Please help.

Thanks in advance.

Hi @RJain.1 

Did you ensure that SysTick is initialized correctly ? Please attach .cpd file to dive further.

Hi @FBL ,

Yes, I have checked systick is working as expected. I am able to get the traces as shown below:

I am unable to get the .cpd file, just captured the traces in UCPD monitor. I am using monitor - UCPD 1.4.0

I have attached my .ioc file.

Please check the configurations.

I am stuck with the project, I just want to access the GUI Interface to get the SINK configuration. please help.

Thanks,

Hi,

I can get the trace and GUI Interface by connecting the UART wires to ST-link UART, but why an ordinary USB to UART converter like CP2102 module cannot display the GUI Interface, only showing traces!!

Hi @RJain.1 

You can save the trace by simply clicking on save trace. 

Check demo implementation and UART configured for GUI interface as a reference.

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 tool. Otherwise, any competitor could use our tool.

Okay, got it.
Thanks!!
