ESP8266 Community Forum

Hello Experts,

I have started working on ESP8266 and right now trying to run blink example using Ardunio IDE but we
have been struggling to execute application on ESP8266 and
our esp8266-01 is resetting again & again with watchdog reset error
wdt reset
load 0x4010f000, len 1264, room 16
tail 0
chksum 0x42
csum 0x42
~ld
Setup don start

We have been using below schematic for the connection and here is the part number.

ESP8266 01 wifi transceiver
D-SUN "USB to TTL" (Blue)

Please advice how to proceed further.

On another ESP8266-01 I don't see output of AT command too .

Just my two cents:
* GPIO0 and GPIO2 should never be left floating.
* The 3.3v line on most FTDIs is not powerful enough.
