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...
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 ...
I'm a newbie to STM products. Lots of experience with other vendors, and am used to seeing example solutions that go from point A to point B. STM seems to provide tool descriptions (and I understand why given the combinations of tools, versions, pr...
I have a stm32f446 setup with a virtual com port. I using a task with FREE RTOS. The task is blocked by waiting on a semaphore (xSemsphoreTake). In my CDC_Receive_FS routine I am simply calling xSemaphoreGiveFromISR when ever this function is called....
Looking at stm32 USB library for USB device (not host)( particularly for 32F769) I noticed in source code, different approaches between core ID 300A and core ID 310A. However I found no documentation that explains that versions. Does someone know wha...
