I'm kind of a newbie to the ESP8266 with regards to loading the newest AT firmware.
I have tried unsuccessfully to load the newest 2.1.0 AT bin into my ESP.
I'm using the RobotDyn Arduino Uno + ESP8266 board http://robotdyn.com/catalog/boards/uno_wifi_r3_atmega328p_esp8266_usb_ttl_ch340g_micro_usb/.
I followed several blogs and the documentation, and downloaded the firmware from https://github.com/espressif/ESP8266_NO ... master/bin
From there I picked the following files:
For the user bin, there are two subdirectories, I used the binary from https://github.com/espressif/ESP8266_NO ... .new.2.bin
Here is the screenshot of the ESP download tool:
And the download log looks like this:
One funny thing I noticed is that the log shows it erases the flash in several places but it's missing a writing message. I expected it to print out some message like "writing at ...".
It didn't show any error either so I was under the impression it worked..
Then after this operation completes the ESP it seems it didn't write the firmware at all.
When I connect to the serial terminal, I can only see data @ 76800 baudrate, instead of at 115200, and only this message shows up:
Can anyone tell me what's wrong?
That helped me start digging a bit more, but in the end I found that apparently I had a corrupted copy of the files.
I downloaded the full zip file from github, then manually selected the files and downloaded again.
Just in case, I moved all blank.bin downloads to the top and then reflashed, and it worked.
