How do I assign port COM3 ton docker image on Windows?

[NordmeyerT]

$ docker run -it --rm --device=/dev/ttyUSB0 -v $(pwd)/esp_wifi_repeater:/home/esp/esp_wifi_repeater martinfger/iot_devel:1.0
docker: Error response from daemon: error gathering device information while adding custom device "C": not a device node.

Removing the --device option allows me to start the docker image but when flashing I get

esp@292d2c4c18bd:~/esp_wifi_repeater$ make flash

I guess I have to pass the approriate --device option but how should it look like?

No complete solution, yet. But seems you have to attach COM3 to WSL first
Use PowerShell

usbipd bind --busid 2-3
usbipd attach --busid 2-3 --wsl

Then you can list attached ports

usbipd 

(i think I had to install usbipd first)

Makefile still contains "/dev/ttyUSB0". replaced this by "/ttyUSB0/ttyS2" as Claude says this responds to COM3 on Windows systems

now I am here

Download esptool from https://github.com/espressif/esptool/releases
and flash it in Windows without docker. It didn't work for me on macOS neither.
But remember to change the -fs parameter to 4MB, or it will not work with the newer versions ...
