Resolved! STM32F407 Discovery External Power + ST-Link
Hello,I‘m trying to power up my development board with a external 5V power source. Is it possible to use the on-board ST-Link via USB at the same time? Thank you for your help. Best regards.

Nucleo-STM32F401RE + ST-Link problem - cannot connect to the target
I have a problem with the connection. Yesterday my board stopped working (there is a file FAIL.txt: "The interface firmware FAILED to reset/halt the target MC" at board disk). I've done some research on how to fix it, but neither pressing reset nor c...
STM32F1-Error debugger
I run into this problem every time I debug. No matter what I did I couldn't fix it. Even though I selected Debug configuration>Debugger>ST-LINK(OPENOCD) and Reset mode>software system reset it still works. I made a chip earese from the ST-LINK UTILI...
STMCubeProgrammer does not program STM32L55
Hello, I am working on NUCLEO-L552ZE board which has STM32L55 Cortex M33 MCU.I can program the device using Keil IDE using ST-Link Debugger option. But I would like to program the device using ST-Link Utility or STMCubeProgrammer. ST-Link Utility can...

STM32G4 USB self powered device / VBUS handling
I am setting up a STM32G4 based USB self powered device with CubeMX. The CDC/ACM stack nearly runs fine. How shall I implement VBUS handling? The part has no dedicated VBUS pin. So some app notes suggest to connect VBUS to a GPIO-extInt or ADC and im...
Resolved! STM32G030F6 OSC_EN
Hello,I am using STM32G030F6, use HSE, but when I set the system clock, PA14 change to OSC_IN but while PA15 change to OSC_EN, and I can't find any specification of this definition, can I use it as OSC_OUT?
STLink v3 Mods not flashing STM32H7 MCU
We have a STLink v3 Mods which is not capable of programming any STM32H7 MCU. The programmer works fine with G4s, F3s, F4s and L4s. Using the STM32Cube Programmer and 4kHz as a connection speed works fine for reading and writing. Higher speeds do not...
