Question

USBCPD SNK not generating file

Hi

I am trying to setup the NUCLEO-G491RE along with a X-NUCLEO-SNK1M1 to communicate with a USBC PD source.
I have tried to follow the STM32StepByStep - Getting started with USB-Power Delivery Sink.
STM32StepByStep:Getting started with USB-Power Delivery Sink - stm32mcu

After generating the code and trying to build the project I get the following error:
fatal error: gui_os_port.h: No such file or directory
make: *** [Utilities/GUI_INTERFACE/subdir.mk:25: Utilities/GUI_INTERFACE/gui_api.o] Error 1
make: *** Waiting for unfinished jobs....

I am unsure how to make this error go away, because as far as I understand it, the CubeMX code generator should give me all the necessary output files to make this simple sink project functional.

I would like to get the GUI to work, such that I can verify the ability to change the power output of the USBC Source.

I attached the generated files along with the CubeMX file.

Thanks in advance.

Hello @LINSS 

Let me thank you for posting and welcome to the ST Community.

The issue has been escalated to dev team under internal ticket: CDM0062124.

I will let you know as soon as the issue is fixed.

As Workaround, I recommend that you generate the code with STM32Cube FW_G4 V1.6.0.

Thanks.

Mahmoud
