Hello all!
I am having difficulty flashing an ESP8266-12F.
The WIFI module is interfaced through an AVR micro controller.
The AVR only shovels date between my windows 7 PC and the ESP.
The AVR is powered with 3.3V so logic levels should be no issue.
I am able to communicate with the ESP using AT commands at 115200 baud.
I am also able to set the ESP module into boot mode and get the string :
ets Jan 8 2013,rst cause:2, boot mode:(1,7)
This indicates to me that the ESP has entered boot mode and that all relevant IO's have the correct logic levels for downloading new firmware.
One odd thing though is that now the baudrate must be set to 74880.
When I try to download a new firmware with ESP8266Flasher the program log outputs only 2 lines and hangs there.
Note:Serial port connected.
Note:Begin find ESP8266.
and nothing else.
I have also tried ESP8266DOWNLOAD TOOL V3.4.4 and get the following in the log window.
TEST!!!!
SELF.COMSTR: COM9
test running : False
BAUD 0 : 115200
test COM: COM9 <type 'unicode'>
test self._COM: COM9
test baud: 115200
======
CONNECT BAUD: 115200
============
com open
com port closed
test type : <type 'unicode'>
COM type: string
is open: False
serial port opened
-----------
baud: 115200
root baud: 115200
-------------
===============
BAUD : 115200
===============
Connecting...

It gets no further and obviously does not download anything.
I have tried all the different settings of SPI MODE with no joy.
I would appreciate any help with this.
