the selected serial port
 does not exist or your board is not connected

The actual unit I'm using is an ESP12S which I believe is a 4MB unit
I just tried with the "NodeMCU 0.9..." as per your screenshot but with no luck. I also tried "Generic ESP8266 module".

- Tue Jan 30, 2018 3:20 am #73571 I believe you have 1m not 4m flash memory, so choose generic esp8266 board and change flash size from 512k to 1m 64k spiffs.
At least that is what I think your error says.
