ESP8266 Community Forum

Hi folks,
It's my first esp and i read alot about it.
It is esp-12f. I manage to put in flashing mode and flash ESPEASY on it.
Flashing went succssful. Than u put esp in normal mode and i stuck in infinity loop with exception:
"Fatal exception (0):
epc1=0x400ef424, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000 "
My setup is preaty simple:
3.3V to VCC, CH_En
GND to GND, GPIO15

for boot mode:
i put GPIO0 to GND and GPIO02 to VCC
for normal mode: GPIO ot VCC, and GPIO02 to GND

for power supply i use my FTDI1232 3.3V pin

With this setup once, it start normaly, i was able to connect to wifi , get IP from esp, but when restart averything gone..

Please advice !

This page might help. There is a good chance your setup does not supply enough current for the ESP8266.
USB to serial chips such as FTDI do not supply enough current @ 3.3V to power the WiFi radio.
