  I'm having an issue communicating with NODEMCU unit after flashing Espruino firmware.

  I'm using the following python cmd to flash the firmware

  python esptool/esptool.py --port COM7 --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB 0x0000 "C:\Users\owner\Downloads\espruino_1v92\espruino_1v92_esp8266_4mb\boot_v1.6.bin" 0x1000 C:\Users\owner\Downloads\espruino_1v92\espruino_1v92_esp8266_4mb\espruino_esp8266_user1.bin
   0x3FC000 C:\Users\owner\Downloads\espruino_1v92\espruino_1v92_esp8266_4mb\esp_init_data_default.bin 0x3FE000 C:\Users\owner\Downloads\espruino_1v92\espruino_1v92_esp8266_4mb\blank.bin
  

  Everything seems to complete when flashing and the Espruino Web IDE is able to connect with the unit after flashing but I am not able to type in the left pane of the IDE and any "require" call such as

  var wifi = require("Wifi");
  

  errors with "Module Wifi not found".

  I am able to upload sketches using Arduino 1.8.1 IDE and the code works fine and the Wifi connects, so I know the NodeMCU unit is not broken(at least not completely).

  Any thoughts as to what the issue may be?

  --UPDATE 5/24/2017--
  I was able to use NODEMCU-Flasher with the same files listed above and got it working.

  Also, I then compared the settings of the NODEMCU-Flasher with the settings I was sending to the python esptool and noticed some differences so I,

  1. Updated the memory locations to match the ones used by NODEMCU-Flasher(OxOOOOO etc...)
     
  2. Changed the flash mode to dio(from qio)
     
  3. Changed the flash frequency to 40(from 80)
     
     

  After those changes I was able to run the esptool using python via command line and all is well! The revised cmd is,

  python esptool/esptool.py --port COM7 --baud 115200 write_flash --flash_freq 40m --flash_mode dio --flash_size 4MB 0x00000 "C:\Users\owner\Downloads\espruino_1v91\espruino_1v91_esp8266\boot_v1.6.bin" 0x01000 C:\Users\owner\Downloads\espruino_1v91\espruino_1v91_esp8266\espruino_esp8266_user1.bin 0x3FC000 C:\Users\owner\Downloads\espruino_1v91\espruino_1v91_esp8266\esp_init_data_default.bin 0x3FE000 C:\Users\owner\Downloads\espruino_1v91\espruino_1v91_esp8266\blank.bin
