Hello

I have a STM32F429I - DISC1 microcontrollers. After mishandling likely, the microcontroller was not started.

When I plug in the USB cable, my computer tells me that the device is not working properly. The only LEDs that are turned on are:

- G2 ((red) for 3.3 V power-on)

- LD6 ((RED) OC  (over- current))

Is it possible to reset the microcontroller or reboot?

Thank you

    Physical damage is not something you can fix with a button.

    If you have loaded some broken software you can strap BOOT(0) to VDD and have the device boot into the system Loader, from where you can erase the errant code.
