Using batch (.BAT) files to help with Flashing ESP8266

Using batch (.BAT) files to help with Flashing ESP8266

Having installed ESPtool.py and downloaded the latest version of Espruino into a folder:
In my case, I created a folder
"C:\Users\jj\Documents\espruinoEsp8266Fl­ash"
and then copied the two batch files into the subfolder
"C:\Users\jj\Documents\espruinoEsp8266Fl­ash\espruino_1v95_esp8266"

Identify the ESP8266 Chip

Plug the ESP8266 into a USB port ( using supporting hardware)
Ground GPIO pin 0
Reset the chip and run ESPinfo.bat

ESPinfo.bat

:: Read ESP8288 or ESP32 chip info
set /p pport=Enter a Com port 
echo %pport%
pause
esptool.py --port %pport% --baud 115200 --no-stub chip_id
esptool.py --port %pport% --baud 115200 --no-stub read_mac
esptool.py --port %pport% --baud 115200 --no-stub flash_id
pause

and the output

C:\Users\jj\Documents\espruinoEsp8266Fla­sh\espruino_1v95_esp8266>set /p pport=Enter a Com port
Enter a Com port com3

C:\Users\jj\Documents\espruinoEsp8266Fla­sh\espruino_1v95_esp8266>echo com3
com3

Press any key to continue . . .

Note the Flash size for the chip I used is 1Mbyte. So I will use a batch file set up to program the ESP8266 with that size flash chip.
Reset the ESP8266 and then run "C:\Users\jj\Documents\espruinoEsp8266Fl­ash\espruino_1v95_esp8266\FlashESP8266_1­M.bat"

:: Flash ESP8288 1M chip with Espruino
set /p pport=Enter a Com port 
echo %pport%
pause

The output:

Disconnect GPIO pin 0 from the ground and reset a couple of times.
Start WebIde and connect to the ESP8266
