Can't upload to ESP8266 with Arduino IDE

I recently got an esp8266, I tried programming it with the Arduino ide, downloading the addon with the board manager of Arduino IDE. I didn't do anything else with it (no trying to get it flashed with other stuff)

I follwed a correct schematic to hook it up, selected "generic esp8266" into my arduino ide board menu, and selected the correct serial port.

But I can't get it to work! Each time I press upload I get an error :

warning: espcomm_sync failed
error: espcomm_open failed

This is really getting on my nerves, can someone help me? :ugeek:
Thanks

Buy something like this:
https://www.sparkfun.com/products/14050

Adafruit sells a similar item and eBay dealers have a wide variety of non-FTDI devices, but make certain that you find one that can do 3.3V and 5.0V using a jumper ... not cutting a trace!

I have 2 of the Sparkfun boards and have had them for several years ... I keep one at 3.3V and the other at 5.0V and have never had an issue. Yes, you pay a little more but you get support and replacement options.

Also, for ESP8266, consider the under $4 NodeMCU by Lolin (and others) that has the USB-serial on the breakout. These are great development boards and I now do all of my coding on these ... then move to another ESP8266 afterward if I need a smaller footprint.

Or, you might just move to Linux and tell Microsoft to shove it ... uC development is a P.I.T.A. under Windows but some folk feel committed to Windows like to a bad marriage.
