ESP8266 Thing - Flash to AT Firmware default.

Post by cyberrat » Thu Aug 27, 2015 12:58 pm

Hi,
I need your help guys ;) .. recently I updated my ESP8266 Thing with the NodeMCU Firmware. But now I want to go back on default AT Firmware. I have some problem to Flash Firmware with the latest version of the firmware. I have found nothing on the sparkfun website to talk about it or how to do that.

Firmware : AI-v0.9.5.0 AT Firmware.bin
Flash Tool : ESP8266 Flash Downloader
Address : 0x00000

Error that I receive at the end.

Writing at 0x0007dc00... (99 %)
Writing at 0x0007e000... (99 %)
Writing at 0x0007e400... (99 %)
Writing at 0x0007e800... (99 %)
Writing at 0x0007ec00... (99 %)
Leaving...
Failed to leave Flash mode

I don't understand what's is wrong. My final objectif is return the unit with the default AT Firmware latest version.

Regards,

cyberrat

there's a big forum of ESP8266 users (not Sparkfun).
A quick Google turned up

This is normal, because there is no possibility to leave the Flash mode. This means your programming was successful.
