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...
Hello,I am attempting to use the built-in bootloader to flash code to the STM32H743 Nucleo-144 using the USART. I have tried two methods: following the flow chart in AN2606 Figure 48, and jumping directly to the bootloader, but so far neither method ...
I'm developing an STM32F429-based high-speed USB audio device that uses a Microchip USB3320 external PHY and would benefit from a DFU mode. Is there an example available anywhere for such a configuration?The default bootloader present in system memor...
hi, I am writing a custom bootloader and its only 20Kb in size, as per the STM32H7 datasheet it looks like I can't erase FLASH smaller than 128Kb, just wanted to confirm that in this case I have to waste rest of the sector data and allocate the full ...
Rev 4 of "STM32L4Rxxx and STM32L4Sxxx device errata" states that"Data FIFO gets corrupted if the write sequence to the transmit FIFO is interleaved with other OTGFS register access"and to work around it,"Ensure that the transmit FIFO write accesses c...
I'm trying to develop application using CAN driver. It looks like the STM32F1 HAL User Manual (UM1850) is outdated.The processor is STM32F103RGT6Where can I find documentation of CAN driver for 1.8.0 Cube version? Or maybe there is somewhere the upda...
Hello there,I don't know if I can call this a bug, but it shouldn't happen at all.Thing goes like this: I have a STM32G071, I enabled UCPD1 and 2, also CMSIS, USBPD library in CubeMXI generated code for SW4STM32, I write my custom board code in usbpd...
Hi All,I think SD_write() and SD_read() in sd_diskio.c (see below) have the timer tick overflow bug. For 30 seconds prior to osKernelSysTick() overflowing (every ~49 days), the functions will incorrectly return RES_ERROR without entering the while l...
Hi, I'm new to STM's. I'm writing program using bxCAN by HAL Layer. I had a problem with sending messages in time interval. For example I would like to send two messages in every 100ms, but when I'm doing it messages are missing, so I would like to h...
Hi all, I work a lot with CubeF4 library using and improving this code. Is there an official way to contribute or share my code, so that everybody can benefit from improved CubeF4 library?
Hello to everybody,my aim is to use the device like a usb pen drive and the memory is an sd card, butI got an issue using project usb device msc_standalone included in STM32Cube_FW_H7_V1.5.0: when I load this to evaluation board STM32H753I-EVAL2 and ...
