Open a command prompt, run mos flash in the directory where the application’s mos.yml exists and you’ll be able to copy the output.

In order to be able to flash the firmware to a ESP8266 with 1M of flash, you should run mos build --platform esp8266 --build-var FLASH_SIZE=1048576. Otherwise the build command will assume the default, which 4M of flash.
