After seeing on http://www.espruino.com/ESP8266_Flashing#initial-flashing-on-windows , I tried to initial flash on windows to NodeMCU device(esp8266-esp12E).
After executing like below command:
But I saw the below error:
python "..\esptool\esptool.py" --port COM6 --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 32m 0x0000 .\boot_v1.6.bin 0x1000 .\espruino_esp8266_user1.bin 0x3fc0000 .\esp_init_data_default.bin 0x3fe0000 .\blank.bin WARNING: Flash size arguments in megabits like '32m' are deprecated.

In addition, the type of my esp8266 board is "esp8266-esp12e-NodeMCU V2" board.
The information of board would be refered to the link, " https://components101.com/development-boards/nodemcu-esp8266-pinout-features-and-datasheet"The page shows belows info. of my board.

Sorry for this question .
I found the miss typo of command "0x3fc0000 .\esp_init_data_default.bin 0x3fe0000 .\blank.bin"
I solved after changing "0x3fc000 .\esp_init_data_default.bin 0x3fe000 .\blank.bin" because of 4MB, total flash size.
Thanks to all.
