Circuit Diagram for Flashing the Firmware to ESP8266.Hardware Setup for ESP8266 Firmware Update.
#Flash esp8266 firmware install
The ESP8266 Firmware can be installed for two reasons: If you want to update the ESP8266 Firmware to its latest version or to completely install the new firmware (in case it was overwritten by any program). So, in this project, we will flash the official Espressif Systems’ firmware for ESP8266 Module using the official ESP8266 Flasher Tool provided by Espressif Systems which is the ESP8266 FLASH DOWNLOAD TOOL and Arduino UNO as the USB to Serial Interface. This leads to a lot of questions like whether the firmware is original or not, is the firmware up to date or not and many other. In my case, I have the ESP8266 ESP-01 Module by AI-Thinker. In the same project, I’ve mentioned that by default, the ESP8266 ESP-01 Module comes with an AT Command Firmware.īut if we write our own program to access the GPIO Pins (like we did in the previous project), the existing firmware will be completely erased and the new program will be written.Įven though ESP8266 WiFi Module is manufactured by Espressif Systems, the SoC is used by many third party manufacturers to implement their own custom modules.
#Flash esp8266 firmware how to
In the previous ESP8266 Project, we have seen how to write our own program in ESP8266 using Arduino IDE and control an LED using the GPIO Pins. This project can also be used if you want to update to the latest ESP8266 Firmware. This is the second project on ESP8266 and in this project, I’ll show you how to flash the Official Espressif Firmware in ESP8266 using Arduino.
