I am trying to update the firmware of an STM32F446RE Nucleo board with Raspberry Pi using usb-dfu protocol using dfu-util library. I want to leave the bootloader mode without actually pressing the reset button on the STM board. How can I do it? Can I do it using some GPIO pin of the Raspberry pi by giving a HIGH or a LOW to a specific pin of the STM board which might be there to serve the purpose of resetting the device as the button does.
Its really urgent
Kindly help.
Thanks in advance
Siddharth
