STM32 MCUs Boards and hardware tools

According to AN4488 for STM32F4 (64-pin in my case), the VDDA pin "must" be connected to two decoupling capacitors. Is this needed for digital-only applications? If not, should the pins be left floating? The ADC seems isolated from the rest of the supply.

STM32F429ZI VBAT pin characteristics to resist short-circuit

Hello,​We use STM32F429ZI on our project now, and the VBAT pin is connected to a button cell as RTC power supply. And we are running a short circuit test on VBAT pin, if there is a short circuit on the VBAT pin, then it means that the positive termin...

I have some problem with stm32h723zg uart

I was working with stm32h723zg uart3 pin. I was using micro usb pin with stlink for uart and It works fine but I relise I have to use 3.3V power for pwr consumption test with stlink-v3pwr so I set jp2 with no jumper, and set on jp1 which it will set ...

I am experiencing failures of the LSE oscillator on STM32F427VIT6 during thermal cycling.

I have an ESC ECS-.327-CDX-1082 32.768KHz crystal on the LSE of an STM32F427.I have read and followed AN2867.All of the boards produced so far have had the oscillator come up initially.All of the boards subjected to thermal cycling (-20°C to +70°C) h...

St-link v2 upgrade to 3.11.3 seems to cause a "target no device found" problem. I was wondering if this is due to me using el cheapo generic stm32f401cdu6 boards? Is there chip counterfeiting happening, and has ST started testing for counterfeit chips?

This problem exists with both a nucleo 446re programmer as well as multiple generic stlink v2 programmers. These programmers will all update successfully from the stm32cubeide. I have tried different debugger settings. This "target no device found" ...
