STM32L433 stuck in bootloader after updating with CubeProgrammer

Hi, I have a custom product/board that has an embedded STM32L433. The STM32 is powered with an external battery. It is also connect through USB to a COM board that runs Windows. The COM controls the boot0 and reset pins of the STM32 which allows me t

LSE clock not starting correctly on STM32F103

Hello everyone,I am using STM32F103ZG MCU in a custom board for more than 7 years; 5 years ago, for shortage issues, I change the LSE oscillator from MC-306 32.768K-E3 (CL=6pF; ESR=50k max) to 9HT10-32.768KAZY-T (CL=7pF; ESR=70k max) and I changed t

tearing down spi connection before stop1 breaks flash write on stm32u375

That pretty much says it all. Any attempt to tear down the connection (disable spi, disable dma, etc) before (long before) stop1 causes flash write after (many instructions after) the wfi to fail with PGSERR error. Not tearing down the connection

STM32H563 use DMA for RX and IT for TX on a UART

I’m just starting a new project using the STM32H563. It has 16 channels of DMA, 8 in GPDMA1 and 8 in GPDMA2. I have at least 11 peripherals I’d like to use DMA for, UARTs, I2C and CAN. That means 22 channels of DMA if I want to use DMA for RX and TX.
