I own an ice40, but need to emulate chips it does not support, so I would like to upgrade it if that is possible.
or is my only option to get trace the AVRone?
Can the AVRone actually do a trace for code on a mega168 or mega324?
it is not obvious to me from the literature.
thanks

You need to ask Atmel about upgrades..
Why is the trace such a necessity? What about regular breakpoints and assert.h? Which AVR toolchain supports feedbacked profiling?

No RSTDISBL, no fun!

I think both were discontinued IIRC.

It seems it can't.

Trace is a great tool but on a single-threaded, small processor such as AVR does it really count as essential?

I can usually debug without emulator. But there are times that not much else will answer the questions.
I am currently debugging a 10kbit/sec protocol I wrote for inter processor communication. occasionally one message doesn't get through. Emulator helped solve it in about a day. I am pretty sure I would still be trying things if I didn't borrow an emulator.

I am doing assembly code, using studio4 - this supports trace (although it is cumbersome).

I have asked Atmel the upgrade question, but have not gotten a response yet.

I got a response from atmel rep - ice40 & 50 are discontinued.
no support available.
anyone out there know what the 'upgrade kit' was?
anyone have an ice50 for sale?
