Resolved! USBPD keeps getting state detached after attached_wait
Hi,I am working on a custom USB-PD board and trying to make a sink. To check if everything was working as is it supposed to do, I followed the "10-minute" sink example from ST. But when I connect a USB source, the sink keeps detaching the connection ...
Resolved! Make EXTI generates a request to DMA1 on STM32H7
Hi,I'm trying to trig a DMA from the EXTI0 input. There is a good example in the STM32Cube package for the H7: Projects\STM32H743I-EVAL\Examples\DMA\DMAMUX_RequestGenBut this example uses the BDMA and I need to use the DMA1. I tried to make some modi...
Why enter the ISO in/out incomplete interrupt? STM32CubeExpansion_USBAudioStreaming_V1.0.0 UAC MCU STM32L476
Hi all:If I plug in USB 2.0 mode high speed port(PC recognition Windows7), frequently enter the ISO in/out incomplete interrupt. but if I plug in USB1.0 mode full speed port,is OK. Once enter the incomplete interrupt.record or playback, audio will b...
Resolved! Can I communicate with high speed device using Full speed host(NUCLEO-F411RE)?
I am working on USB CDC ACM device. I want to communicate with High Speed device using full speed host(NUCLEO-F411RE). As I am new to USB protocol, but I know that device starts communication in FS mode and switch to HS mode only if host respond to J...

Resolved! HRTIM update using LL is too slow
Hi Everyone,I am trying to run HRTIM Master unit with repetition interrupt and the repetition counter is 1. Now, when I am in interrupt I have to update compare and period registers and using LL to do so. But, within interrupt merely updating registe...
STM32Cubef7_v1-16-0.zip stops downloading with Forbidden
The software almost finishes download and then quits with forbidden. This is using chrome on Windows 10. I am trying to learn the F767ZI that I just received. Ideas?
RTOS is not working in STM32F072.
I have created a project in STM32CubeIDE with UART and some GPIO's as Input and Output.I have created 2 Tasks using FreeRTOS - CMSIS v1(osPriorityNormal, osPriorityBelowNormal) with different osDelay(osDelay(500);, osDelay(600);). I have compiled and...
Tool for flashing over CAN using system memory bootloader
Hi,We are developing products using STM32F746ZE. We have a requirement for fashing the device using on-chip bootloader over CAN interface. We found tools(FLASHER-STM32) on the ST website, which can be used for flashing through UART.Similarly, for the...
