Arduino fio avrdude: stk500_getsync(): not in sync: resp=0x00

I have tried EVERYTHING to make this work, including replacing the board.

I have an arduino fio

I am attempting to upload a sketch to it (just a blink to validate it works) with an FTDI to USB cable

I am using Arduino 1.5 BETA and I also tried Arduino 1.0.5 Neither of which worked and resulted in the same error.

I attempted to use a different comp with a fresh install that resulted in the same error.

I updated my FTDI driver to 2.0.8.30 still the same error

I dismantled the FTDI wire and re-soldered it to new wires to verify it wasn't a bad connection.

I attempted setting the baud rate in device manager to 9600,57600, and 115200

I tried pressing the reset button as I uploaded the sketch

I tried changing COMS

I tried plugging an Arduino Uno in, validating that it works no problem. Then I plugged the fio back in. Got the same error again same error.

This is the second board I have gotten that does this. It's not the board. What the hell is wrong with this software. I shouldn't have to work this hard to upload a freaking sketch.

IDE output

avrdude done.  Thank you.


And yes, I have tried restarting both the IDE and the computer(s).

• Has it worked in the past? Oct 8, 2013 at 3:41
• Yes, which is the most irritating part. When I first got it (about a week ago) I uploaded a blink sketch to it and it worked. 1 week has gone and it has been sitting on my desk untouched. NOTHING has changed Oct 8, 2013 at 3:41
• Hmm. Check out this page and see if any of the various posts there are helpful: forum.arduino.cc/index.php?topic=28223.0 Oct 8, 2013 at 3:54
• That is where I got many of the solutions I tried above Oct 8, 2013 at 4:03
• @OlinLathrop Olin, in this case I defend his position. I'm pretty sure that "base" and "bit" meant something else before electronics, yet no one complains here. These terms are specific to a product, so it's correct to use them in that context. Nov 8, 2013 at 16:31

So I went out to microcenter today and bought ANOTHER new arduino fio. I also bought a usb to FTDI breakout board instead of a cable.

For ish and giggles I attempted to load a sketch onto my old arduino with the new breakout board. Worked instantly.

5 Hours wasted and lesson learned. Try a new cable if you get this error.

I had the same issue in windows 7.
