Hi, i'm doing a project and i need some information. It is possible to get an electrical diagram of the ST-LINK / V2 ?

STM32- Nucleo-L476RG schematic: Why is PB12 (Pin 33) connected to V_ref/VDDA (Pin 13) ?

Hello,I'm designing a new schematic for am IOT project with STM32L476RGT and looked for reference in the schematic of the Nucle-L476RG. In this schematic the  V_ref/VDDA (Pin 13) is connected to PB12 (Pin 33). Why are these two pins connected?

STM32G030F6P6 Running at 2.5V - Can I use STLINK-V3SET in SWD Mode?

I have designed a prototype based on the STM32G030F6P6  microcontroller. The microcontroller runs on a battery. The power to the microcontroller comes from a 2.5V regulator. Is it possible to debug this configuration using an STLINK-V3SET in SWD m...

Upgarde Nucleo H743ZI2 to segger J-link

I have upgarded several old NUCLEO boards without any problem. All boards ware equipped with ST-LINK-V2 debugger I've tried to upgrade two new Nucleo boards board equiped wit ST-LINK-V3 .Result : Both returns error during upgrade. See attached scre...

Hi, I am trying to flash stm32f103 board. I am facing connection lost issue. For more details check attached image. Thanks, Aditya

Implement ST-link design in my own boards

I successfully made a PLC board with a Nucleo development board on it.Now we are ready to ramp up production, we like to implement the Nucleo board design in our own board design.Because we make use of ST-link for drag en drop new firmware via mass-s...

Custom board and ST-LINK : can't get a program to run on power up

Hi guys. I'm somewhat new to STM32 programming.I did a program that I can start on a custom board using ST LINK V2 debugger / programmer. If I unplug the ST Link, it continues to work well. However, if I power off the board, I can't get the program t...

LAN8742 PHY does not work properly on STM32 F437VIT (Custom Boards). Everything properly wired?

Hey!I want to use the LAN8742A on a STM32F437VI.Unfortunately it doesn't work as intended. I have the suspicion that sth is not properly wired because the Ethernet LED's doesn't light up after powering up. The initialization via LWIP doesn't work pro...
