#47041 Hi,
I'm new to ESP8266.
I've read some guides on getting started with them and while they all differ in a few ways, they all say that I should be able to type AT or AT+GMR etc in to the terminal window and get a response. If i reset the device with a BAUD rate of 74800 I get the following in programming mode (GPIO 0 tied to GND):

Code: Select allets Jan  8 2013,rst cause:2, boot mode:(1,7)


If I remove GPIO 0 from GND i get the following message:

Code: Select all ets Jan  8 2013,rst cause:1, boot mode:(3,6)

  SPI Speed      : 80MHz
  SPI Mode       : DIO
  SPI Flash Size : 32Mbit

I have tried changing BAUD rates and typing AT commands with no success.
The firmware I flashed was:

boot_v1.2.bin - 0x00000
user1.512.new.bin - 0x01000
blank.bin - 0x3E000
blank.bin - 0x7E000

I am using an AI-Thinker ESP8266 12F and I'm completely confused by the above 4 files so any help would be greatly appreciated :)

#68318 I have exacly the same problem. It's the ESP-01 with the lastest firmware from https://github.com/espressif/ESP8266_AT, i'm getting the "jump to run usererror user bin flag, flag = c
user code done" error (?) message.

Please someone with the solution?

#70910 Hi guys,

I'm trying to put the AT firmware on my ESP-12.
I got that same error as @CraigDubya.

I'm using the newest "ESP Flash Download Tool" (version 3.6.1.0) with these settings.

Thank you in advance.
