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 ...
SDIO with STM32U575
Hello everyone! I'm working on a project using an STM32U575 microcontroller, and I need to manage an SD card (read, write, etc.) via SDIO in 1-bit mode, but without using FreeRTOS. I noticed that FatFs is not natively supported for this MCU in STM32...
Resolved! How to configure sdmmc for SD card in stm32h7s7 with FATFS
Hi,Im trying to configure SDMMC 4 wide bus with FATFS for SD card.Im not able to see any DMA options or Platform setting to set SD detect GPIO pin.am I missing something? I have refered through most of the documentation and tutorials online but with ...
EEPROM Emulation issue on STM32G0B0CET6 in RTOS task
Hi,I'm currently using an STM32G0B0CET6 and encountering an issue with writing a uint32_t variable to EEPROM using Write_U32_Variable(). The function works correctly during task initialization and in normal bare metal while loop too, but it fails whe...
Pending a transfer on an I3C controller and target to happen after an IBI
I am using two STM32H503 boards. One is programmed as an I3C controller, the other as an I3C target. My goal is to have the target send an IBI on the bus and the controller will receive the IBI and then immediately issue a pended read -- there will...
Resolved! Call HAL_ETH_ReleaseTxPacket() from ISR context?
I am connecting a TCP/IP stack to the HAL_ETH driver of an STM32F7xx. I am using https://github.com/STMicroelectronics/STM32CubeF7/blob/master/Projects/STM32F767ZI-Nucleo/Applications/LwIP/LwIP_HTTP_Server_Netconn_RTOS/Src/ethernetif.c as a starting ...
