STM32H7A3ZIT6Q Custom PCB – ST-LINK/V2 Detects 3.22 V but Shows "No STM32 Target Found"

Hello STM32 Community,I am currently working on a custom PCB designed using the STM32H7A3ZIT6Q (Cortex-M7) microcontroller. I am trying to program the MCU using an ST-LINK/V2 debugger through a Tag-Connect adapter, but STM32CubeProgrammer is unable

Wrong conversion time on ADC and two samples instead of one.

Hello,I am using NUCLEO-U5A5ZJ-Q evaluation board.I have configured ADC1 to do a single conversion and a software start.I want to measure ADC conversion time.My main test code looks like thiswhile(1){ HAL_ADC_Start_IT(&hadc1); HAL_D

Problem loading STM32WB5MM RTC prescalers

I have used STM32CubeMX to change the prescalers in the STM32_WPAN section. However, the code itself never uses the new values. It appears that “something” has marked the RTC as already initialized and it won’t execute that code.How can I force my co

stm32mp135d-odyssey outdated buildroot repositories

Hi listI am testing the STM32MP135d-odyssey for a project. It is small, still cheap, has support for POE and on board ethernet connectors and SD-card holder. The buildroot repositories are quite old so I wonder if the board is in actual use and can b
