Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Dear CommunityI am working on a project right now, using a STM32H725 with an external PHY (USB3300-EZK).The board is working and using FreeRTOS with CMSIS I have USB HS working.But trying to build my project on Azure with USBX, I can't get USB HS to ...
Hello,I have a STM32L4 and I need it:To be able to communicate with a laptop via USB (PC = Host, L4 = Device)To be able to communicate with a custom made USB device which only support being a USB Device (L4 = Host, Custom device = Device)I managed to...
Dear all,I'm working on a project based on STM32F479 microcontroller and I'm using STM32CubeIDE as IDE. The system uses an RTOS (in particular FreeRTOS) and I have reserved a working area into the microcontroller's flash memory to store system inform...
We received chips labeled "STM32F427VGT6 990C8 VQ MYS 99 141 4".Initially they failed to boot at all, but SWD debugger connects ok.The option bytes had BFB2=1, causing system memory to be mapped at 0x00000000 independent of BOOT0 state. After changin...
I am building a UCPD sink by referring to the following page. https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_SinkI would like to build a UCPD sink using interrupts etc. without using the RTOS. Is there any c...
Background:I am programming a FreeRTOS and CubeMx based application on the STM32L4S9AII6 MCU. For several months now, I have been fighting a memory based bug described in great detail here: https://community.st.com/s/question/0D53W00001X3HmWSAV/whack...
I want to communicate directly with a full speed CDC device from my STM32F769 running in USB host mode but I only have a high speed OTG USB port available. From example code for other STM32 devices it appears this is possible but can anyone confirm t...
I have a project that inadvertently appears to have what looks like the bootloader area.I'm using STM32CubeIDE and when I program the board from the IDE, it runs fine and all is ok. If I press the reset button then the board ceases to run.I've duplic...
I am working on enabling feedback for the PLAYBACK endpoint using STM32H750XB. I was successfully able to control the packet transfer between host and device based on feedback data sent to host, it plays for hours, no issues at all, no rollovers, no ...
