I'm experiencing FDCAN Memory Access Failures on the STM32H503KBUX during CAN Rx. I am also experiencing intermittent CAN Rx message drops (every 1 in a 200), and I believe the two are related since no others errors are firing. I know the drops are h...
The Reference Manual for L4 series (RM0394) says on page 1007:"When the LPTIM is running with an asynchronous clock, reading the LPTIM_CNT register mayreturn unreliable values. So in this case it is necessary to perform two consecutive read accesses ...
Hi,I'm working on a design containing a STM32U535. I need to connect it to a SDHC interface (µSDHC connector). The STM32U5 documentation talks about a SDMMC1_CKIN signal. It is not clear to me if this signal is always required or not. I think the doc...
I am having a problem reading SPI data on an STM32F407 where it always returns 0x00. I actually have this working using HAL on the same hardware, however for legacy reasons I need to get this working with SPL. This application is just sending clock s...
Hello,Is it possible that STM32f207ZGT6 purchased in 2025 from an official distributor have an old silicon revisionrev_id = 0x200f?
According to some reference it is good to have ground polygon under IC 1. Is it okay to have ground polygon under IC? 2. Does it effects heating issue?3. I saw two hole behind the IC of nucleo 144 board. What that mean?
Hello, I am using firmware STM32CubeF1 v.1.8.6, the STM32Cube MCU Package for the STM32F1 series. The folder name in the Repository is STM32Cube_FW_F1_V1.8.6 (version 1.8.6).In order to stay current I downloaded the latest the patch for STM32CubeF1, ...

Dear ST Support Team,I am developing a USB-based device using the STM32H755 microcontroller.In order to ensure proper identification of the device on host systems, I would like to requestthe allocation of a unique USB Product ID (PID) under STMicroel...
Hello we try to use the backup sram on 0x3880 0000 .We have build the software :#define BKPSRAM_BASE 0x38800000UL #define BKPSRAM_SIZE 0x1000UL typedef enum { BkpSram_Init = 0 , BkpSram_Wait = 1 , BkpSram_WriteStr = 2 , BkpSram_ReadStr = 3 ...
