[avr-gcc-list] Which ICE to get?


G'day all.

I'm just starting with AVR programming. The project uses at ATmega128,
and an STK500 board. However, I'd also like to get a JTAG device for
in-circuit testing.

My question is: Should I get a mkI or mkII?

I guess the question is really: What do the Linux tools work with?

Many thanks in advance, etc.

Cheers,
Andrew Bromage

That depends on whether you're willing to fork out the money for an
mkII one or not. I don't think buying an original mkI would make
sense anymore at all (if they are still available), but of course,
there are a number of cheap clones including DIY ones. For the
ATmega128, there's not much difference between both, except the mkII
protocol is a bit safer in handling. With the mkII one, you're open
for new MCUs you might want to use in future, while the mkI appears to
be a dead end now, i.e. I don't think Atmel will provide firmware
upgrades that make it support more MCUs, and the XML files for the new
devices don't mention mkI support either.

With both ones now. For downloading code, it's already just the
opposite currently, avrdude 5.0 supports the JTAG ICE mkII but not yet
the mkI (though I just committed the code for that to CVS). For
avarice, there's no released version yet that supports the mkII one,
but you can download a CVS snapshot, and it's my intention to roll an
avarice 2.4 release in the near future.

Never trust an operating system you don't have sources for. ;-)
