Random failure to upload code.

I do have a mkII for in circuit programming, although I had hoped that using arduino would mean I could leave it collecting dust :wink: And thanks for the advice about not doing 100 before I do a working prototype, I will definitely do that. It's good to know that I can at least change the time the bootloader waits for powerup. I am not entirely clear on how the bootloader can change the timing for reset, but I assume it's just outputting 5V through a resistor into a capacitor connected to reset?

Actually (sorry, I'm new to the arduino platform), there appears to be an option for using the arduino "as an ISP". Does that mean I can burn a bootloader by using the existing bootloader? Huh? If that was the case, I'd be pretty excited, because then at least it's just a two-step programming operation that I could script to happen from a single command without having to do multiple wiring jobs.

Thanks for that debug info Coding Badly. It outputs a lot of stuff, but it scrolls by quickly and the buffer isn't long enough to see the beginning by the end... do you know if I can make it send the debug output to a file? In any case, I captured it in the terminal and this is what it said:

Does this sound like the "resetting too soon" issue Grumpy_Mike suggested to everyone else as well?
