Arduino UNO Wifi - home.html page

Hello,

I am using UNOWifi Firmware updater tool method to update the firmware.
It requires user1.bin and user2.bin files.

How can i generate the above bin files (windows platform) from the the 'factory' firmware source code of arduino.org's Arduino Uno WiFi board - "GitHub - bcmi-labs/Esp-Link: Control Panel and connectors for Arduino Uno WiFi".

Thank you.
