Am just getting up to speed on bootloading. I haven't seen how to deal with this situation in the info I've found.
I will not have physical access to the device, but will be connected via RS232. I will need to tell the device to go into bootload mode from the other side of the RS232 connection. What I've seen so far requires an input to a port pin to indicate to the device to bootload. Is there a common way to deal with what I'm trying to do?
Also wondering where to find a well documented bootloader. As I recall, Atmel has one on their site. Is there anything that may be better in some way? I'm using ICCAVR.
