That is basically where your program will jump to the bootloader, but you would have had to coded that portion. Atmel has an example of that on their website and I do use it. Basically, host software will communicate to your MCU and tell your MCU to jump to the bootloader. However, that will not help you in this case unless you have coded it. I modified my original post to tell you the necessary hardware conditions that should work. So, try out the hardware conditions in the previous post and if you cannot get them to work you will have to get another chip. Also, I neglected to mention that youll need to have the ALE disconnected, but no one ever uses this pin and is usually left unconnected.
