esp8266-12e flashing problem!!!
Posted: Mon Jan 08, 2018 11:19 amHello guys 
I got some problems with flashing any kind of programs to esp8266-12e.
Beside that, the AT Command doesn't work either. When I power up the esp, it sends a message to serial with a buderate about 74000. The message says:
ets Jan 8 2013,rst cause:1, boot mode:(3,7)
load 0x40100000, len 2408, room 16
tail 8
chksum 0xe5
[And some other stuffs]
[And some information about second boot version and SDK version]
Then stops working. Actually freezing. No AT Command responses, no flashing(arduino ide says: espcom open failed) just nothing
In addition, it's all right when I change the esp, esp07 works good, but I need this one.
The wirings: gnd & vcc is connected to reliable power source(3.3v) gpio15 >gnd.
In flashing mode, gpio0>gnd. Tx Rx connected to usb to ttl converter. ch_en > vcc. And when I disconnect and connect the ch_en the message comes again.
How can I solve it??? :'(
Thank you all.
