HI, i have esp-12f , and try my first time flash. I manage to setup flasher and flash esp-easy firmware.
Flashing finish successful, than i put gpio00 to VCC and disconnect GPIO02 (It must be normal boot mode), but only thing i can see on serial port is infinity loop with message:
Fatal exception (0):
epc1=0x400ef424, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

my setup is:
VCC, EN, GPIO00
GND,GPIO15,
nothing more.

Make sure to supply enough current for the ESP8266. See the following for details.
