STM32 MCUs Boards and hardware tools

Why can't VDD-USB be tied to voltage derived from USB VBUS, even when VDD is OFF? If they need to be tied together, than the USB will disconnect every time VDD is OFF and will need to be re-connected. It should maintain this connection when VDD is OFF.

Does the STM32L072VBT6 or STM32F072VBT6 not allow for the USB connection to function, even when VDD is OFF?

Resolved! why is LD3 (red power led) working with 3V3 input on NUCLEO-F072RB ?

I have this board (revision C-04) with ST-LINK removed (PCB cut off), so the power 3V3 is supplied from CN7. It works fine, but the red power led (LD3) also works. LD3 is, I think, connected to the 5V net, and 5V to 3V3 regulator should not be workin...

Change OSC_IN pin with OSC32_IN ?

I am using STM32F030C8T6TR. An external 8 mhz oscillator was connected to the OSC_32_IN-OUT input by mistake, not to the OSC_IN-OUT pins on the board I have. Hardware cannot be changed. Can I reconfigure the pin with software or How can I use it? I a...
