  Thanks Wilberforce for your reply.
  I have already tried that many times.
  I had even pressed the reset button on my board.
  I even tried flashing using the Flash button on the board. By plugging in the USB while pressing the Flash button.

  This is the board version I have. see attached.

  Hi All,

  I'm a newbie to this, so please bear with me.
  Trying to load the latest Espruino firmware 1.94 to my ESP8266 12E boards. It came with Node MCU and I used it to flash Arduino programs through it's IDE and it worked perfectly.
  I have 3 ESP8266 units and tried flashing Espruino on all of them and had no luck.

  My Os is Windows 10 Pro (64bit)

  Symptoms:

  • I do not see any flashing errors. All flashing programs seems ends successfully.
    
  • Espruino IDE communications Baud rate is set to 115200
    
  • At first connect from Espruino IDE, it says disconnected (see picture).
    
  • At second connect from IDE, it connects. But on the terminal prompt I cannot type anything. prompt does not accept any text (see picture).
    
  • I used PuTTY, still the same. I do not see a thing. Cannot type any text at the prompt.
    See attached pictures please (see picture).
    
    

  Tools used to flash firmware:

  • nodemcu-flasher (see pictures for it's configurations)
    
  • esptool.py
    
  • For python I use Enthought Canopy
    
  • firmware I used for my board is "espruino_1v94_esp8266_4mb"
    

  • I did a erase flash. command line for that

    python "../../esptool/esptool.py"  --port COM4 erase_flash
    

    esptool.py v2.2-dev
    Connecting....

    Erasing flash (this may take a while)...

  Command line I used to to flash to board,

  python "../../esptool/esptool.py" --port COM4 --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB 0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.bin
