Error when Initial flashing on windows

Posted on
  • 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

    A fatal error occurred: File .\esp_init_data_default.bin (length 128) at offset 66846720 will not fit in 4194304 bytes of flash. Use --flash-size argument, or change flashing address.
    
    
    

    Please let us know how to change --flash-size argument, or change flashing address.

    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.

    Please let us know how to change --flash-size argument, or change flashing address.

  • 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.
