ESP8266 Community Forum

My ESP8266 resets itself after flashing.
After completing the flashing process, it stay with the code for aprox. 5 secs and then resets.

I'm using Arduino IDE for ESP8266 v2.0.
GPIO0 to GND.
Reset to a Tact Switch to GND.
CH_DT to VCC 3.3V.
Using FTDI FT232RL in 3.3V.
Using external power source for the ESP8266.

What could it be?

How do you power the ESP ?
You need a strong power supply ...

I use 3.3V 1A external power supply.
PS: Somehow after many attempts it happen to work. The code remained. I reached that twice when changing the board selected on the IDE. When I tried for the third time, it gone back to resetting after flashing.

do you have a serial monitor, does it initially show any thing ?
does it show any thing after a reset ?
