ESP32 Forum

Hello;
Acccording to my System Device Manager, my COM Port is COM5.

I am using Windows10, and according to a hint ypo can check your port by connecting / disconnecting from USB
, while typing "ls /dev/tty*" into the Msys2 MinGW terminal:

I have noticed that my Settings for the serial flash tool port are: "/dev/tty /dev/ttyS4"

In the end i got the following error message:

"serial.serialutil.SerialException: could not open port '/??/COM5': WindowsError( 3, 'Das System kann den angegebenen Pfad nicht finden.') --> "System can't find the Path"


Any ideas why this happens and how to fix ?
I have added some Images about it.

Note: I tried "ttyCom5", and ttyUSB0" before also ithout success.

Thanks for your helping hand

Hi ruppie,

Did you try COM5? We ship the MSYS2 environment with a Mingw32 (native Windows) Python. The main reason for doing that is (ironically) so that the fiddliness of Unix-style port names isn't required.
