Hi,
i have the correct port selected and usw Arduino now for a few month.
SInce yesterday the port worked well. And if i connect an Arduino Nano for example it works.
Only with an ESP8266 it doesnt work.
First i thought, that the ESP is damaged so i tried another one - same fault.
So i tested it on my windows machine --> everything works (also with the ESP).
So i installed Manjaro Linux completely fresh and also Arduino.
Added the board url and installed the ESP via board manager and : Again it doesnt work...
Any further suggestions?
