user29553: When I was trying to blink an LED using ESP8266, I had an issue with it. After successfully uploaded the code (https://diyhacking.com/esp8266-tutorial/), the blue LED stayed on & when I opened the serial monitor using Arduino IDE 1.6.12, I only saw "Fatal Exception" error (showed in the picture). I couldn't see how the code works and the worst thing was I couldn't even try the AT command.
The connections:
Arduino <--->   ESP8266 (ESP-07)
Tx  <--->   Tx
Rx  <--->   Rx
GND <--->   GPIO0
GND <--->   GND
3.3v<--->   CH_PD
3.3v<--->   VCC
            GPIO2 -> LED 

I have been trying to troubleshoot this issue but haven't got the solution yet. I am afraid there is an issue with the firmware or the worst situation, I spoiled my ESP8266.


user28569: Looking at your serial monitor window it shows "Geuino Uno". I think you forgot to change the target of the compiler to "Generic ESP8266" like shown in the how-to and you probably uploaded bad code to your module.
