I can't seem to get the firmware to flash onto my ESP8266. In the flasher I have my firmware chosen, I have GPIO0 to ground and I hit flash and the wheel turns, the blue LED blinks, but the progress bar never starts moving or anything. I checked the Log and it seems to be stuck on "NOTE:Begin find ESP8266."
Does anyone know what I need to do to get the flasher to find the ESP8266 and get the firmware flashed?
Thanks
Perhaps if you provided - by way of an inline image in the post, an absolutely perfectly focused photograph of your arrangement taken in full daylight (but not direct sun) with all connections unobscured and explain either by posting it in "code" tags or a link to where you obtained it from, what software you are using to perform the flashing; we might be able to see what is causing your problem.
And you need to specify what exercises you have successfully performed with the ESP8266 prior to attempting this code flashing.
The first is a (poor) photo of my setup. There was no way to take a good picture of it so I included the schematic I followed in wiring it up.
I'm fairly confident that the hardware wiring is correct. I have been successful in communicating AT commands and getting strong responses. (However, AT+RST responds with the normal block of info then at the end where it should say ready, it says invalid. I guess that could have something to do with it...) I have also been able to get the IP address through AT+GMR. I have successfully PINGed the ESP8266 using that IP address.
As I noted earlier, the Restart results with "Invalid" which is why I wanted to update the firmware. The current firmware on the board is 0.21.00.0
mateyb:

OK, that's the first important thing.
I think you need to describe just what software you are using for the upload.
Sorry there mustve been a problem upoading the photo...
anyways, I downloaded the nodemcu flasher from github and I'm using the win 64 version.
SOLVED!
I'm not sure what I did to finally make it go, but I have solved the problem. Thank you for your time
Computers are sometimes like that.
I too have problems uploading firmware.
Esp passed the AT command test but, the sensor data was not getting updated on thingspeak so thought of updating the firmware. I donot have usb-ttl convrter but i flashed the esp using arduino itself and i doubt of not updating proper firmware what can i do now?
I could flash the esp using esp8266 flash downloader tool
this one: http://www.xess.com/static/media/uploads/blog/devbisme/2014-12-09/flashing_done.jpg
but could not do the same using this:

i didnot get proper firmware file also there are many files to be uploaded and the former tool allows to upload only one file.
In all this now after burning a "bin" file my esp is not even responding to the AT COMMAND TEST...
