Hi,

I am thinking of getting a Dragon to debug an Atmega168 via debugWire and gdb under Linux. Looking at the AVaRICE source code, it seems that debugWire s/w breakpoints might now be supported, yet the documentation still says they are not. So, before I spend any money, I just want to find out what the current state of play is regarding avarice + debugWire?

Are debugWire software breakpoints supported?
Can I single-step through programs using debugWire?
Can I examine variable values using debugWire?

Thanks,
Matt.

I'm watching with interest and may contribute in due course. After several successful months of using AVR Studio and AVR-gcc under Windows, I managed yesterday to compile AVR-gcc under linux, with a view to building a version with the fixed-point patches (mentioned in another thread here) included.

Assuming I get that far it would be convenient to do the rest of my AVR development work under linux, so the Insight/GDB/Dragon/debugWire combination is an obvious way forward.
