ESP8266 Community Forum

Hi! I wanted to program the LED blinking example to the ESP8266 with Arduino, using a programmer adapter (This is the configuration what i'm using: . I pulled GPIO1 to gnd, and i managed to flash the example project. But however, it seems that the chip is not responding, actually nothing happens. I uploaded many other examples, but nothing happens. Of course I removed the pull-down from GPIO1. I flashed back the original firmware (with the help of this link: https://medium.com/jungletronics/flashing-the-official-espressif-firmware-in-esp8266-arduserie-17-2234fc088076 but neither the AT commands working. Has anyubody faced this kind of issue?

That programming adapter is a nice little tool, but are you sure it is working? If you have a generic USB-serial adapter, you may want to double-check. This is the way I did it a few years back:

Good luck,

Problem solved, programmer is working. All i had to do is to set flash mode to DOUT instead of DIN.
