STM32G071 USB PD dual role port data disconnects when changing from sink to source

I am using STM32G071 for my USB PD application. I have one dual role port(default sink) and one sink port for charger. When I attach charger I change the role of drp from sink to source. But hub chip in the application gets disconnected when I change...

Resolved! STM32G071 UCPD Dead Battery pins does not work.

I have STM32G071 MCU to control a USB Type C hub and I want to use VBUS Powered sink in the application. I have connected Dead Battery pins to their respected CCx pins. It supposed to act as a sink when there is no power but when I connect the type c...

STM32G071RB: USB PD application, REQUEST_DISCARDED debug message from PE.

HelloI am building an USB PD application.- MCU: STM32G071RB- Tool: STM32CubeIDE (Firmware version 1.6.1)I am using 2 USB PD ports (UCPD1 and UCPD2).The power role of UCPD1 is DRP, and UCPD2 is Sink.And I am reading debug messages through STM32CubeMon...

Resolved! What is the minimal configuration required to support USB C PD on the STM32G071 line?

Hello everyone! I'm very new to USB C PD so bear with me.I'm currently designing a very simple temperature controller board that uses a USB C PD power supply. I am using a STM32G071C8U3 as the host MCU. I have connected the CC1 (PA8) and CC2 (PB15...

Hi. We are using your company's NUCLEO-G071RB and X-NUCLEO-SRC1M1 to evaluate USB-PD. We were able to confirm the output voltage is 5V, but if I want to change the output voltage to 9V or 15V, how would I build the proxy?

Why does ST32CubeMonitor + DISCO constantly disconnects

I just bought a STM32G071B-DISCO because I was looking at using an ST32 in my USB-C application and I'd hoped this could be an analyzer and a starting point. However it constantly disconnects and loses contact with the board. No refreshing brings it...

Resolved! How To Run 2 UCPD ports on CMSIS V1

Hey allI am building an application using a STM32G071RB with a DRP1M1 as ucpd 0 and a USBDP1 (old SNK1M1) as ucpd 1 and new to the STM UCPD worldIn an attempt to start from a working base, I used the DRP1M1_DRP example project as a starting point. Th...

Resolved! USBPD Core library calling reset handler on DISCOVER SVID Reception

When my STM32G0B1KET receives an Discover SVIDs message, it responds GOODCRC, then the core library function PE_StateMachine_VDM() calls the reset handler. After reset the system hardfaults. System responds to discover identity properly. The USBPD_VD...

Trying to move over G0 DRP example code, the UCPD tracer program stops seeing the board

I am trying to build an application with a SNK and DRP usbc port, using a USBPDM1 and a DRP1M1 with a nucleo g071rbI have successfully run the DRP example application, but when I try and add the functionality to my sink application stm32cubemonitor-u...

Resolved! Why do I not receive a USBPD_NOTIFY_SRCCAP_SENT notification?

I am trying to set up a sourcing power delivery port on an STM32G0 system. I have set up switching of VBUS, and when I connect up a sinking device my system detects it, sets up VBUS and starts sending source capacity messages.Log:<Connect source to p...
