Answer : Know this is old but I ran onto it during my search for Nano(V3)'s not uploading so thought might help someone else. Problem is the bootloader - Arduino IDE BUT I Found an easy solution (right under my nose). I realized that my nano's had been uploading just fine then I had finally updated the Arduino AVR Boards from 1.6.20 to 1.6.21. I didn't think there was any problems because it still showed my Nano and ATmega328 etc in the board manager after the change.

I changed processor: In the Arduino IDE select TOOLS > PROCESSOR > pulldown menu from ATmega328P to "ATmega328P (Old Bootloader)" . Since then, I have uploaded many programs to several different Nano's V3 (Prolofic interace Chipset) without issue. This error message basically shows up for any communication problem, so by itself, it is not all that instructive. The Arduino Nano is supposed to have au...
