STM32 MCUs Embedded software

How does one design a circuit where an STM32H7 is never unrecoverable?

Per section 2.6 of RM0433 (https://www.st.com/resource/en/reference_manual/rm0433-stm32h742-stm32h743753-and-stm32h750-value-line-advanced-armbased-32bit-mcus-stmicroelectronics.pdf), when the STM32H7 boots up it latches the boot pin and then goes to...

MCU can't enter or exit to/from bootloader mode only after power on

Hi, My MCU is STM32G441VBT6 , this MCU is on PCB I designed myself and I use UART3 in bootloader mode.My boot0 pin is connected through resistor 10k to GNDAnd the reset pin is connected to push-button (parallel witch capacitor 100n) and GND.MCU start...

STM32F4 clock configuration tool generates code that causes USART baud rates to be 2x too fast

I am using the STM clock configuration tool STM32F4xx_ClockConfiguration_V1.10.xls to generate the system_stm32f4xx.c file for a project using a STM32F407 processor with a 16MHz HSE. I am also using the Keil MDK-ARM V5.23, and the STM32F4xx_DSP_StdP...

I am using STM32F030CCT6TR microcontroller for my Bootloader, but the while switching to application there is an error in initialization of System Clock.

I am blinking LED every 4 sec for up to 5 counts in Bootloader and switching to Application where I am blinking LED every second.But while jumping to Application the Clock Initialization is failing.

STM32L452RET6P VDDUSB Pin

Hi all,I'm using the STM32L452RET6P in my PCB design.I would like to use its USB Device feature and unlike some other STM32 i encoutered, it seems that here there is a special need in VDDUSB pin on the MCU.Can someone help me understand how to use th...
