Hardfault on USBPD_PE_StateMachine_DRP
I am developing a USB power delivery solution involving the STM32G0B1. I have already followed the tutorials for creating a simple DRP application on a Nucleo devkit and they work as expected.To my understanding there are two paths that we can take; ...
Resolved! USB C PD Try.SRC and Try.SNK
I can't find Try.SRC or Try.SNK features for DRP devices in ST's USB C Power Delivery Stack (USBPD Core). Did I miss something?If it is not in the stack yet. Is ST planning to integrate this feature? What timeline are we looking at?Is it easy to impl...

USB Device CDC ACM
Hello,I am working on USB device CDC ACM for STM32N655L0. I found an example about "Ux_Device_CDC_ACM" for NUCLEO-N657X0-Q. Can I use this example for my mcu? How can I find ioc configuration of this example?I also tried to implement this example to ...
STM32H723 wrong data when interfacing QuadSPI & OctoSPI RAM
Starting from a working application based on the STM32U585A microcontroller, we changed the CPU to have the ETHERNET peripheral available. The flash is connected via quadSPI to the microcontroller, while the RAM is connected via octospi .Microcontrol...
