I am trying to flash the Micropython Firmware on my ESP32 via USB via the CMD (admin mode) on Windows 8.
This is what im getting:
C:UsersAdministratorDownloads>esptool.py --port COM3 --baud 460800 write_flash --flash_size=detect 0 esp32-20190207-v1.10-54-g43a894fb4.bin
esptool.py v2.6
Serial port COM3
Traceback (most recent call last):

raise SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port 'COM3': PermissionError(13, 'Zugriff verweigert*', None, 5)
- Zugriff verweigert == Permission denied
What can i do here? Im not sure if this is an error on the OS side or on the script - i dont know what could possibly deny me permission when im using admin CMD?
- i read through this: https://stackoverflow.com/questions/6105182/error-while-opening-port-in-python
but turning the COM port off and on did not help.

Is the port perhaps in use by another program? Though the error message would probably be different, hm.
