I just got this and can't get the code to upload. it says this:
Binary sketch size: 1018 bytes (of a 14336 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
Any idea what's going on?
ps. it's the blink example.
Check the troubleshooting guide: http://www.arduino.cc/en/Guide/Troubleshooting#upload
That was the first thing I tried. It didn't help. But i think i figured out the problem. Here is the new situation:
the ftdi drivers will not install. windows seems to think it knows what drivers i need better than i do. it says windows has determined that drivers for "Unknown USB Device" are up to date. I know what files need to be installed. isn't there a way to force install them or something?
I just bought two Nano 3.0's (sn11BP0202, and 11BP0203). Same thing. No driver recognized. For either of them.
I have an Arduino Uno which comes up fine. When I plug it in, all of a sudden /dev/tty.usbmodem411 shows up. Downloads work. Life is good.
Plug in either of the Nanos and /dev/tty.usbmodem411 goes away... leaving a couple of Bluetooth modems which do not work to communicate to the Nanos. When I try to download, I get:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding
It's not the cable. It's not the particular Nano 3.0 (unless I got two bad ones).
I'm running MAC OS X, and Arduino 0022
Something's broke.
Well, good news... (at least for me).
I downloaded the latest FTDI drivers ( http://www.ftdichip.com/Drivers/VCP.htm )
and things got good. Interesting since my previous drivers were not that old.
Both boards now load.
Thanks for the forum and I hope this helps.
Good day!
I’m doing a project using my arduino nano version 3.0 and I had encounter several problems regarding it..
Here are my problems:
Can anybody in this forum help me out solve my problem?
Thank you.
Hi guys, I just found the easiest solution to INSTALLERS, FTDI, Software Updating and stuff. These guys from CZ just uploaded the driver for solving these issues on arduino Nano. Worked for me, hope it works for you.

So, just to help anyone else running Mountain Lion (10.8.5) and a Nano V3.0 ATmega328 CH340G:
My system:
Macbook Pro with 10.8.5
My Nano I got off EBay and it's full description is:
Mini USB Nano V3.0 ATmega328 5V 16M Micro-controller CH340G board For Arduino
So, I was able to get things to work finally. I first tried the recommended (above) link:
http://www.ftdichip.com/Drivers/VCP.htm
After install (but no reboot) I didn't see the desired files. I didn't know you had to reboot. 
So, I am pretty sure it would've worked. Regardless, since I didn't know about the reboot, I did a bunch of searching and finally got this driver:
[CH341SER_MAC.ZIP from http://wch.cn/downloads.php?name=pro&proid=178](http://CH341SER_MAC.ZIP from http://wch.cn/downloads.php?name=pro&proid=178)
and finally had the sense to reboot. It worked.
Anyway, just wanted to say thanks to you all for posting the ftdichip info and hope this helps others that may have had problems like I did. I think when I begin to get more serious I will use those and also get the official Arduinos. But for my budget, this approach has got me started.
Thank you.
Hi - just got one of these: Mini USB Nano V3.0 ATmega328 5V 16M Micro-controller CH340G board For Arduino, - needs a CH340g driver - found one & brief description at Модуль CH340G. Переходник USB COM TTL (RS232). - It 's a zip file, opened & worked ok. This site also has drivers for Windows, Linux, Mac.
Regards
I've tried the two European websites referenced for the Windows drivers for NANO. Norton is preventing me from installing from either. So I'm lost. I'm having the same issues as others: my Uno and Mega boards register cleanly and automatically but my Nano boards don't. Windows finds no drivers for them. I'm holding my hands up in futility and surrender. Help please. Kurt
Start by posting a link to where you got them from so we can check which USB to serial chip it uses.
I purchased them on eBay from nyplatform.

Thanks for the help in advance.

The driver for that board is the FTDI usb to serial driver. They are signed so Microsoft should not have a problem with them. The drivers are here.
OK. I installed the drivers you listed. The Nano appears on Com3. But when I upload/compile to it I get the following error messages:
Binary sketch size: 3,220 bytes (of a 30,720 byte maximum)
processing.app.SerialNotFoundException: Serial port 'COM3' not found. Did you select the right one from the Tools > Serial Port menu?

@KurtSignals, What com port do you see in device manager with the Nano plugged in?

Thanks this worked for me, after I tried the FTDI drivers http://www.ftdichip.com/Drivers/VCP.htm
When I plug in my Chinese Nano clone into my WinXP laptop USB port it shows a "USB Serial Converter" is loaded into my Device listing under "USB Serial Controllers". From reading many postings on this subject I see I need to download a different driver called CH341SER. I found the zip file, downloaded and unzipped it into two directories: DRIVER and INSTALL. Now when I double click the USB Serial Converter item and click on the Install New Driver choice, I have directed it to these directories. Windows looks at them and informs me that this driver is no better than the current installed driver (or similar language) and refuses to install it.
How can I force the installation of CH341SER?
Thanks.
Firstly check the USB to serial chip on your board to confirm it is the CH340. If it is the drivers are here.
The chip is an FTDI FT232RL. It also says 1402-C and CN480661. Thanks. Any ideas?
