Not typical "avrdude: stk500_getsync(): not in sync: resp=0x00"

First of all, yes I have read about 40 forum posts on this subject following every single tip given by anyone.

To this point, there are facts:

  • My board is original Arduino Uno R3, it is selected in Tools menu with proper port
  • Getting this error on both windows and MacOS on different computers (Device itself is seen by system, working properly)
  • No shield or any extension is connected to arduino (or anything else to any pin, everything is disconnected)
  • Bootloader is surely OK (read down below about usbasp)
  • I have done this test http://forum.arduino.cc/index.php/topic,73748.0.html with positive results, connection is OK, getting echo
  • Fusebits are set properly (Checked them with ISP programmer)
  • When I connect arduino using my USBAsp programmer it works, I can burn bootloader without error, uploading blink sketch resulting in blinking diode.
  • Playing with reset button when uploading does nothing, tried many many times

Does anyone have anything else to recommend in this situation?
Arduino stopped working by itself randomly, I uploaded some sketches ok and then bam error.

That error usually means the '328P is not responding.
Did your latest sketch do something to tie up D0/D1? Like blast out tons of serial messages?
Try this: File:preferences, turn on verbose outputs.
Start a download, and press & hold the Reset button.
When you see "Compiled xxx of 32xxx bytes", release the reset button.
May take a few tries to get the timing right.

My latest sketch was working with 2 devices on l2c, one LCD displaying digital sensors parameters and time from second device connected to l2c, Real Time Clock. And then this happened.

Info I'm getting from newest beta arduino GUI on MacOS:

Now I'm fooling around with the reset button as You suggested, no luck so far but I will try anyway

Now, after many tries with resetting I can say it failed. I even replaced the atmega328P chip itself to my friends arduino uno chip with blink program loaded but problem still exists, my chip in his arduino communicates without problem.

Loopback test proved that communication with arduino is ok, chip itself is ok, so what else could fail then?

Carefully inspect the board. Any damaged traces? Any pins shorted to each other? Do the 5V and 3.3V levels measure okay at the power header? Is the Reset voltage at 5V?

Powered via usb 3.0:
Reset measures 4.81V
5V measures 4.81V
3.3V is exactly 3.30V

Powered by external 12V power adapter:
Reset measures 4.98V
5V measures 4.98V
3.3V is still 3.30V

No visible damage on both sides, just finished inspecting them with jewler's microscope.
I think I'm going to pass on this device and buy new one :confused:

Might be best. Hard to offer more long distance.

Hello all,

I have same error "avrdude: stk500_getsync(): not in sync: resp=0x00". I use arduino uno, windows 8 and arduino v.1.0.5. I get the error when I upload on arduino uno board, but in arduino mega 2560 work fine... please give a hint whether the board is damaged or that IDE ???. I post error log on here
:

anybody can help me solve the problem? I will very appreciate it. Cheers from Indonesia

I try debuging in setting preference check all verbose "downloading" and "upload", and when i upload sketch, I get message like this :
