Ok, before I start, just let me say, I've found the 'Exit debugWire' button on the Dragon control panel when finishing up a debug session.
What I'd like to know, is what exactly AVRStudio is doing when I press this button.
Why? Cus I want to understand how it does what it does.
You see, from what I've read, when the target chip's fuse is set for DWEN the only viable way to get it reset is to use HVSP (Tiny25). So I tried that, and it didn't work! The chip was on my target board with a full 6 pin ICSP cable and power supplied from the Dragon. (I've not populated all the headers/Zif on the Dragon yet, that's this afternoons project).
So, if I can't reprogram the fuse using HVSP off board, how the Dickens does AVRStudio do it?
