#20902 I think that configuration available from http://arduino.esp8266.com/package_esp8 ... index.json
are not compatible with Your board (from photo)
Check your:
..\packages\esp8266\hardware\esp8266\1.6.4-673-g8cd3697\boards.txt
and compare it with:
https://github.com/esp8266/Arduino/blob ... boards.txt

flash mode is different ... probably You have "qio" for nodemcu but for this new board should be "dio"

so...try to copy all section "nodemcuv2.name=NodeMCU 1.0 (ESP-12E Module)"
from board.txt available on github to Your boards.txt file
restart Your arduino, select new board NodeMCU 1.0 and try again
