Resolved! EXTI Interrupt Not Triggering on STM32-G0B1RE (HW & SW Triggers Fail; SysTick OK)
Body:Hello STM32 Community,I’m facing an issue with EXTI interrupts on my Nucleo-G0B1RE board (STM32G0B1RE). The EXTI interrupt doesn’t trigger, even though the configuration appears correct, and I’ve tested both hardware and software triggers. I’ve ...
Resolved! Derivation of 12-character USB serial number in STM32C0's system bootloader
How does the bootloader in the STM32C071 system memory generate its 12-character USB serial number string descriptor (e.g. "205537C24236")? I notice some similarities between this serial number and the 96-bit unique device ID at address 0x1FFF7550, ...
Resolved! STM32F411 "User specific sector"
I'm developing a tool to gang program STM32 products. I'm currently working on the STM32F411 (reference manual RM0383) and the FLASH_CR register SNB field mentions two sectors: user specific sector and user configuration sector. The user configuratio...
SPI_MOSI pin does not drive a certain logical level in SPI master mode
Hello, ST experts PB3&PB4&PB5 pins are configured to SPI_SCLK,SPI_MISO,SPI_MOSI in STM32U595VIT6. The code framework is generated according to CubeMX. It works well when communicating with its partner(TI's 32bit ADC), and HAL_SPI_Receive() is called ...
GPIO inputs pushed LOW upon HSE failure
I'm using an STM32H733 running from HSE clock with CSS disabled.In a normal situation, the used GPIO inputs correctly read as HIGH as they are pulled HIGH by an external pull-up / LVTTL (push-pull) drive, verified with the oscilloscope.After exposure...

Resolved! stm32f746 sdmmc 1 Bit vs 4 Bit Data
Designing custom board based on STM32F746G-DISCO. I am using the TQFP chip, so a few less IO. The DISCO board uses a 4 wide data, but I do not have enough pins so I will only have 1 bit wide data. I only want to use SD card to be able to upload n...
