Well, any esptool operation really ends with timeout like below. I tried esptool from github (v4.5? the latest) and v2.5 (old versions even fail detecting the mac). The module is on breadboard with five 10K pullups/pulldowns. This is the first time I am trying this tiny module, espp8266 with usb-serial on board ("nodemcu"?) always worked so I am really not sure sure about this one, any hints?
