ESP8266 Community Forum

- Fri Jul 03, 2015 12:32 pm #22365 I see the "...boot mode:(1,7)" at 74880 then garbage keeps pouring on the terminal.
This is using PuTTY and TeraTerm. I've tried every baud rate I can think of and/or have found mentioned on this forum.
Is there some way to blast it back to the stone age and start from scratch?

- Sat Jul 04, 2015 8:59 am #22424 I've finally managed to connect it to a Windows computer and see the boot messages. This is what I got:

Code: Select allets Jan  8 2013,rst cause:2, boot mode:(3,6)

Any ideas what the problem could be?

- Sat Jul 04, 2015 10:07 am #22430 Dear all,

I also got the same problem!

My PIN configuration:

* Flash Mode:
- CH_PD, REST, GPIO15, GPIO2 = VCC 3.3 V
- GPIO0 = GND

- After flash firmware (example: AT firmware) without reset (unplug and plug power) I can perform AT command via baud rate = 115200
- If I try to change GPIO0 to HIGH or FLOATING and reset -> I can't access serial any more (seem the esp8266 is fail to boot in this case).

So I you can fix this issue, please let me know.

Thank you so much.
