I just joined forum and searched for the above error. I see plenty folks have reported the problem here, and many more on Google as well. But, there is no solution to date. Looks like there is an issue between Visual Micro and Atmel Studio. Has anyone been able to resolve the problem please? Following is the final part of the file I get with my run of Blink program. It runs fine when I use the Arduino IDE directly. But, never with VM running through Atmel Studio 6.1 or 6.2. I tried all Baud rates if that was the problem, but to no avail.
Thank you.

avrdude done.  Thank you.

Thanks Tim. I am using an Arduino Uno board (model R3) through a standard USB upload. I am not using a programmer. If there are tweaks that need to be done for this route, I would appreciate pointers towards my mistakes / changes that I need to make for this route to work.
Thank you.
