I want to clear all pending interrupts in my bootloader before jumping to the user application, otherwise an interrupt will remain pending and therefore other interrupts wouldn't be triggered in the user application.After reading the Cortex-M datashe...
I am working on power management and I put MCU in sleep mode (no low-power), but it doesn't wake up when it receives a CAN frame, it stays in sleep mode. I would like any CAN frame to wake up the MCU.To switch to sleep mode I use :HAL_SuspendTick(); ...
ST is unveiling STM32 Hotspot on GitHub, which comprises repositories developed by ST employees for demos or example features that are not part of the official ST GitHub page or the traditional STM32Cube ecosystem on ST.com.Developers now have access...

We are using STM32G0B1CBT MCU in our product. We assembled 10 pieces and out of 10, 2 devices are randomly going in hard fault sometime instantly after reset and sometime even after 1 hour. What would be the cause? What measures should be taken to re...
Hi,I'm using the UART functionality in NUCLEO-H745ZI-Q board. I want to transmit with UART polling and receive with interrupt. Every time I am able to transmit the characters on to the putty but sometimes receive interrupt is not working. I'm using H...
I am using stm32f030 Tim1
I have connected an external clock to TIM1 and I want to count the values where the counter register is overflow with interrupt. My code is like this, but it doesn't work. TIM_ICInitStructure.TIM_Channel = TIM_Channel_2; TIM_ICInitStructure.TIM_ICP...
I'm unable to find any information on the STM32H7 instruction prefetch behavior (from QSPI/octospi).My usecase/problem: I have a piece of startup code (executed from external QSPI) that moves the main application into (executable) RAM (this is basica...
The STM32 Selection Guide 2021 Shows that STM32F407VET6 contains 512K flash, but actually the flash could be wroten from address 0x0800 0000 to the 0x080F FFFF, So what's the problem?!
