STM32F756VGT6 DFU USB not working

I have used DFU USB to program hundreds of STM32F7 devices over the past several years. It has worked reliably until the most recent batch of 200 boards using STM32F&56VGT6 devices. We had approximately a 10% failure of the DFU USB connection (USB no...

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...

where can I find STM32F107 of IEEE1588 routines

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.
