I had found this before, but it was so _old_ I'd disregarded it. As I read more it looks like a good jumping off point. It points out places I can get information - Like avarice (in this document) says it can only support hardware break points. DebugWire however only supports software break points which means that you can't debug a DebugWire only device with avarice, only the bigger ones that use JTAG.
Ah, well then, the document is old. Joerg added s/w breakpoints some time ago, so first of all you can do breakpoints in DebugWire, and secondly, on JTAG parts you can have more breakpoints than you have breakpoint registers as avarice simply overflows into s/w breakpoints. It still think you are out of luck with respect to data breakpoints, however.
Hopefully the document is still correct w.r.t. getting the loopback port working for remote debug.
<head shaking> I'll have to decode the more current documents to see what gives there. It appears that many of the devices that I use from Atmel support neither JTAG nor DebugWire, I'll have to upgrade.
? What doesn't use either one or the other? -dave
