Resolved! STM32G070 booting problem after option bytes (user options) modifying/recovering
Hello, I am developing a home appliance application on an MCU STM32G070CB using X-CUBE-CLASSB package and IAR EWARM IDE V8.32.4. I used NUCLEO-G070RB for the early development. The app ran fine until I turned on the SRAM parity check in the options b...
Resolved! STM32CubeMonitor-UCPD "message rejected for this port configuration" when requesting Power Profile
Hello, I'm able to connect the STM32CubeMonitor-UCPD with NUCLEO-G071RB and X-NUCLEO-SNK1M after following the instructions in AN5418. I only changed port 0 Sink PDO1 to 0x020641F4.I want to use the setup as a sink and always want to get the maximum ...
How to force a DRP usb PD3 port to source mode?
Hi, I am implementing a system with two DRP ports using an stm32g0 runnig a full USBPD stack. One of the ports is connected to a powerbank (usb pd v2). The other is connected to either a charger, which is used to power the system and charge the power...
For UCPDx controller, I want to configure a sink for 15V/3A(45W) use STM32G0B1RCT6. What's the meaning of UCPD number for 'GP' version LQFP64 package?
Hello, I find there are a note for 'GP' version LQFP64 package.In blank of UCPD, which has the number "1" .The note is: One port with only one CC Line available(supporting limited number of use cases).Is that mean only one UCPD controller( UCPD1 or U...
Resolved! Dynamically set PDO with G0 and ucpd - charge through dongle
The background is I am trying to build a pass through or charge through dongle like application. Using a G0 with 2 UCPD ports, port 0 as sink, and port 1 as DRP, using the respective TCPP chipsMy goal is to have the input port 0, get the available PD...
Safety Critical Application
Hi everyone, We are developing safety device which need to go in a fail safe mode in any kind of failure to achieve SIL2 or SIL3 level of safety. And we want achieve UL certification.And we are using STM32G0B1CBTx MCU. And for writing code I am refer...
How do I open the UCPD SNK1M1 Sink project from Github in the STM32CubeIDE?
Initially I followed the tutorial at https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_Sink#-5BOPTIONAL-5D_Advanced_USB-PD_application but couldn't get that to work. It shows negotiations in the STM UCPD softwa...
Should BSP_USBPD_PWR_VBUSOff() and BSP_USBPD_PWR_VBUSOn() of the USBPD library block until the VBUS voltage is ok?
Hi,We try to implement a DRP device with the USBPD library on a STM32G071 uC.From the documentation the requirements for the following functions are not clear:BSP_USBPD_PWR_VBUSOff():- Should it block until VBUS < USBPD_PWR_LOW_VBUS_THRESHOLD?- What ...
Resolved! Is There a Way to Hack USB-PD on STM32G030K8?
Hi All, I designed my board with a STM32G0 series MCU with the main intention of using its USB-PD peripheral. I later realized that it is only the STM32G0x1 series MCUs would be capable of USB-PD while I will be receiving a board turn with an STM32G0...
