Thank you for a good start for setting it up.
It is not working for me yet.
Any idea with what i do with this?
Looking for upload port...
avrdude: Error: Invalid -P value: 'COM17'
Use -P usb:bus:device
Witch I understand is that Auto-detected is wrongly formated for the -P.
I see that @Fernando_Fontana used this:
upload_flags = -P$UPLOAD_PORT -b$UPLOAD_SPEED
upload_port = COM4
upload_speed = 19200
But there is no so to say “:device” there. How is that formated?
Thx for your help
