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...
Hi,I attempt to free the 1st sectors of the MCU flash by relocating the firmware and its interrupt vector table to further sector (e.g sector 5 at 0x08040000 address). For that purpose, I updatedthe linker (IAR) configurationthe vector table location...
Hello!This function was defined and used instead of memset to reset mbedtls's sha256 context. Is there a good reason behind this choice?https://github.com/STMicroelectronics/STM32CubeH7/blob/master/Middlewares/Third_Party/mbedTLS/library/templates/ha...
Hello,I have this board that I have to use for the project. I am using STM32H7S3H8 and 4x MEMS microphone, and I am strugling to get to the point where only math with CMSIS-DSP is important. Is there any example, .ioc file that I could look up to for...
I've written a flash-based bootloader for the STM32F4 using the latest STM32CubeMX tool and its HAL libraries. I've avoided all the usual pitfalls (it's not my first bootloader), and my code works reliably. I'm not erasing my bootloader segment, writ...
I'm working on RTC smooth digital calibration on an STM32U575 board using the HAL function HAL_RTCEx_SetSmoothCalib(). I'm using the LSE (32.768kHz) as the RTC clock source.What I'm trying to do:I want to adjust a known RTC drift (e.g., 500ms) over t...
Hi,On the STM32N6570-DK board, I’m running an application that uses TouchGFX and FileX.Both the TouchGFX frame buffer and FileX temporary buffers are located in external memory (XSPI1).I’m observing intermittent write failures when SDMMC IDMA is used...

Hello,We have developed a product based on STM32M4 and would like to enable our clients to do DFU firmware update. We have develop a Windows based app which will include STM32_Programmer_CLI and make use of it. Although we would need our client to in...
Hi,I am using a NUCLEO-G071RB development board. I accidentally erased the original bootloader while flashing a custom one. Is it possible to reflash or restore the built-in bootloader on the NUCLEO-G071RB development board? If so, where can I obtain...
I am having issues when writing a buffer that is declared in the external buffer to an SD card. When I tried to download a bulk file (1.5MB), write failure (f_write returns FR_DISK_ERR) would happen at least once during the download process, but if I...
