I have designed an audio device based on a STM32H743 MCU. For synchronization purposes I need to be able to count incoming USB frames.To achieve this, I use TIM5 in slave mode, with ITR8 as its trigger. The results are puzzling. I am getting either 1...

I am trying to use the built-in bootloader in DFU mode on STM32H743IIT.1. I built my application and created a *.dfu file2. The bootloader starts fine and my device enumerates properly as "STM Device in DFU Mode"3. DfuSe Demo (v3.0.6) detects my devi...

I am working on a USB device based on a STM32H743 MCU, using ThreadX/AZURE and USBX.According to RM0433 (the reference manual for STM32H742, STM32H743/753 and STM32H750), the USB peripheral supports:- bidirectional endpoint 0- 8 IN endpoints- 8 OUT e...

I am trying to implement a USB audio device using ThreadX/AZURE and USBX, mostly by following instructions from: https://docs.microsoft.com/en-us/azure/rtos/usbx/usbx-device-stack-supplemental-2#usb-device-audio-class It's been pretty frustrating, un...

I am trying to get Azure-RTOS/ThreadX running on a STM32F4-DISCOVERY board.I generally followed the instructions from https://community.st.com/s/article/how-to-create-a-thread-using-azurertos-and-stm32cubeide except:- I (obviously) picked a different...

Same port of the same host. I don't have a Linux host handy right now, but can probably find one later if I have to.I tried reading the FNSOF field. Well, this is interesting. FNSOF is incrementing at the expected rate on all boards. The timers are s...

I made the task blink a LED every second (10 periods on, 10 periods off) and there is no difference between the boards. I also made the boards output (over a USB serial port) the TIM5->CNT register every period, and sure enough, one increments 1000 p...

TIM5 registers attached. The values are identical in both sets of boards.I have a ThreadX task, with a 50ms period loop. In each iteration, I read TIM5 CNT and compare it with the previous value. The results I am getting are either 50 (as expected) o...

For some reason, STM32Cube Programmer can't find my device.I actually tried using your HEX2DFU tool, but it gives me an error message:F:\M595275-00>HEX2DFU.exe M595275-00.hex -out M595275-00.dfu HEX2DFU 0.01 Copyright (C) 2013-2017 sourcer32@gmail.co...

STM32H743, USB2 SOF events happen normally or at twice the expected rate.

DFU bootloader issues

ThreadX/AZURE and USBX unable to use all available endpoints?

Has anyone managed to get a USBX audio device working on STM32 MCU? Do any official examples exist?
