ESP8266 Community Forum

Sometimes my ESP8266 , on power on hangs on bootloader. Its stuck there and then if I just restart it by turning power off then on it works normally.
I checked serial output of it on baud 74480 which is its bootloader output ,in the hang state it just shows some lines till boot mode and then no serial on any baud rate.
I failed to know the reason. I tried different code but I don't think the code is problem . It just randomly stuck at boot sometimes. Can anyone help me ?

Hi
Have you found a solution to your problem, because we experience the same with our propriety board
Thanks

Forgot to mention (I'll also add it in your other thread @Eli Lurie), but this concerns you both: the ESP is very picky when it comes to power supply, especially at boot time (this is the time everything is started, including the actual WiFi radio), since then it needs the most power.

Make sure you've got ample and solid power at 3.3V which can provide at least 300mA (but preferably > 500mA) of current.
