Arduino Troubleshooting for avrdude: stk500_get sync():not in sync,resp=0.00 :roll_eyes:

  1. Make sure you have the right item selected in the Tools > Board menu. (yep)

  2. check that the proper port is selected in the Tools > Serial Port (done so)

3)check if the drivers for your board are installed correctly is by opening the Tools > Serial Port menu in the Arduino software with the Arduino board connected to your computer (have done so, many times)

board = SparkFun Arduino Pro At328, 5v,

  1. Physical Connections (Yes) :fearful: :roll_eyes:

First make sure your board is on (the green LED is on) and connected to the computer. etc, etc (checked all)
Make sure there's a bootloader burned on your Arduino board. To check, reset the board. The built-in L LED (which is connected to pin 13) should blink. If it doesn't, there may not be a bootloader on your board. (yep, it blinks)

I've gone thru the whole troublshooting list, to no avail.

There seems to be no answer to this problem. Does anybody know what causes it?

Did you try pushing the reset button just after the sketch finishes compiling?

EDIT: Also, are you using Arduino 1.0? If so, were you using an earlier version (for example, 22 or 23) when you were able to download to it before?

yes, I'm using arduino 1.0. and I have pushed that reset button at all different times.

There seems to be no hope. I'll have to find a hobby that is more amenable to my nerves.

That is annoying.

There seems to be a rash of this dreaded "not in sync" error message erupting on this forum. I too caught the problem when I was trying to download to a Really Bare Bones Board (RBBB) Arduino, but pushing the reset button at the appropriate time solved it for me.

Others seem to have caught a different disease with the same symptom. Hope someone finds a cure.

UPDATE: You did not happen to use pins 0 and 1 for anything, did you? Like Soft Serial communications?

Thanks for the help
No, I have nothing hooked to any pins, just the FTDI board

You mentioned in the other thread that you have a new FTDI board. Did the problem start when you started using that board? Or did the problem start when you had changed nothing from before?

I know it adds to the frustration when you get questions rather than answers. But sometimes the reset line on FTDI boards can cause a problem. I'm wondering if that is what is happening here.

Things grow increasingly complicated. The Sparkfun FTDI board is new as of yesterday. The Sparkfun Arduino pro is over a year old, and I have been able to upload sketches to it in the past using a FTDI board that I had bought from Fundamental Logic(FL)
(http://store.fundamentallogic.com/ecom/index.php?main_page=product_info&cPath=6&products_id=14)

I have also been able to upload sketches with the FL board to other arduinos like RBBB boards, but now that FL FTDI board doesn't work either. HOWEVER, I have a FL Iduino board, which includes a FTDI uploader, that I can upload sketches to one or two AR168's that I have on hand.

As you can see, things just get more complicateder as I go along. So I ordered an Arduino UNO from Sparkfun, and hope that will be usful

That is indeed a complicated mess! I can see why you are frustrated.

You know more than I do about this, so I have little to offer but sympathy. I suspect, although I have no real evidence, that the timing of the reset sometimes does not work.

With my RBBB, the automatic reset did not work, and I got the not in sync error. What I ended up doing is disconnecting the reset line going into my RBBB, and doing the reset by hand. That worked for me.

But it sounds like you have tried everything like that.

Good luck to you with your new UNO.

I did have get ----> The "message" - avrdude: stk500_get sync():not in sync,resp=0.00

  1. Don't give up yet...
  2. The bare bone Arduino do blink if you apply power ? yes... without the FDTI connected...
    --> If yes. The Arduino chip is working.
  3. The FDTI board from Sparkfun have to be connected in that way :

FDTI TX ----> RX Arduino
FDTI RX -----> TX Ardiuno
FDTI DTR ---- > 0.1 uF cap -----> Reset Ardiuno

Try that... and see what happen..... re-load a blink code and see what happen. In theory, that should work. Work for me.

If you haven't tried going back to an earlier IDE and trying it, then that should be your next move. I hand many others ran into this same problem with 1.0 and any " non standard" Arduino bords
