How to update ESP8266 firmware with NodeMCU

When you purchase new ESP8266, Some of the AT commands does not work with this version and need to update AT firmware to get more functions. NodeMCU is a firmware programmer application for ESP8266 SOC (system on chip) programming. 

What would be needed to program ESP?

1. USB to serial converter (Need voltage divider circuit to allow 3.3v communication)
2. NodeMCU application
3. Firmware version.

Download NodeMCU application:-  https://drive.google.com/file/d/0B886Kbl42IVuU3c3TEpjVU9GMVU/view?usp=sharing

Download Firmware:- https://drive.google.com/file/d/0B886Kbl42IVuRnNPcEMtUHB5WDA/view?usp=sharing

Follow Steps for configure ESP8266:-

1. Make the circuit as per given circuit diagram.
2. Set GPIO-0 pin low during programming. After programming leave GPIO-0 pin free.
3.  Download these bins to the specified address.

 Bin                                              Address

boot_v1.1.bin------------------->0x00000

user1.bin------------------------->0x01000

esp_init_data_default.bin---->0x7C000

blank.bin------------------------->0x7E000

Unzip downloaded files, Select Config menu in NodeMCU application and click on gear icon to set the given address with specific file name.

If you are using to upload other firmware version, read “ReadMe” file and set file address according given detail.

After setting file and address, click on “Operation” button. Set your serial port and click on Flash button to upload firmware files.
