When you download the latest firmware , there are many folders in there ,
In the bin folder there are again too many folders :

esp_init_data_default
boot_v1.4(b1)
user2.2048.new.5

and more and more .

Why is this company cant do things normal ? everything is a big mess, and if you want to do something big
its almost impossible with their bad support/website/data sheets/etc

Anyway , what .bin file do you flash from the tones of files in this folder ?

thanks .

I am a beginner with this too, and I agree, there's a lot of versions, releases and various information all over the place and it's hard to find which is the latest firmware and where to find it. In fact I don't even think there is a single latest firmware, because there seem to be multiple vendors, e.g. Espressif and AI-Thinker, and each has their own firmware. Mine is AI-Thinker and I can't find their latest firmware as their site is all in Chinese. I did find this though on the Espressif site:

http://bbs.espressif.com/

and after a few clicks (under Documentation / FAQ -> Release FAQ list), you get, eventually to this page:

You would think the answer would point you to the latest firmware, but instead, after a few more clicks, you get to choose between Non-OS SDK v.0.50 and Free RTOS SDK.

Also, is the firmware from different vendors interchangeable? Can it be installed on any esp8266 version?

Someone please have mercy on us and shed some light.

Actually, here's something useful:
