CHAPTER 2 • ESP8266 SOFTWARE
• The firmware is broken down into several files (3 normally) and these files need to be provided to the ESP Flash Download tool, together with the corresponding addresses found in the readme file. The files are listed in the NON-BOOT section of the file and they are (the folder and sub-folder names may be different on your PC): eagle.flash.bin in sub-folder ESP8266-AT-Upgrade\ESP8266_NONOS_ SDK\bin\at\noboot eagle.irom0text.bin in sub-folder ESP8266-AT-Upgrade\ESP8266_NONOS_ SDK\bin\at\noboot blank.bin in sub-folder ESP8266-AT-Upgrade\ESP8266_NONOS_ SDK\bin • Fill in the file paths and addresses (offsets). Notice that file blank.bin appears twice with 2 different offsets. After filling in the paths and addresses you should have a screen similar to the one shown in Figure 2.16. The paths and addresses are shown in detail in Figure 2.17.
