2.2.2 ESP FLASH DOWNLOAD TOOLS This is the official tool for updating the firmware of ESP8266EX. The tool is maintained by “Espressif Systems”. Download and extract the latest version of “FLASH DOWNLOAD TOOLS” from the official Espressif web-site. The archive is usually located under “Tools” sub-group at the web-page with the ESP8266EX. Now, depending on the firmware we want to use, we need to select one or more files in the ESP Flash Download Tool Download Path Config panel. Each of these files must be loaded to the correct memory address. This information should be in a Readme file in the firmware archive file. I managed to flash to AT ver 0.5.0.0 using ESP8266 DOWNLOAD TOOL (as you describe above) with the default settings. My next step was to integrate with Blynk ( www.blynk.cc ), their support forums recommend the latest AT version (1.1 or higher) as stable. Weak function wifisetbackupmac for setting user MAC. MbedTLS support. And download espinitdata.bin into flash, when the system needs to be initialized, or RF needs to be calibrated again. We also recommend using the flash download tool to tweak the settings as per your requirements and click GenInitBin to generate espinitdata.
How do you completely erase ESP32 flash chip using Flash Download Tool? This has been tricky for a long time (LONG time, especially in case of the ESP8266). This has been made simple in the latest version of the Flash Download Tool.
This version of the Flash Download Tool comes with a simple “Erase” button. This lets you completely erase ESP32 flash memory.
This is something you should do every time you get a fresh ESP module and plan to run your own custom firmware on it.

Note that we are not providing a link to the new Download Tool because the link changes rather frequently. You can find the Download Tool on Espressif’s official website. The one download tool supports all of Espressif’s chips (ESP8266 and variants as well).
It would probably be a good idea to select the flash size manually rather than just rely on the automatic size detection. Murphy loves ESP developers most!
