68300

I use the '376. Great processor.
As for debugger, I use the visionClick/visionProbe setup. I have used 
the Metrowerks and evaluated SingleStep.
I generally use the Diabdata compiler. But I use the Metrowerks as 
well. Even when I use the Metrowerks compiler, I still use the 
visionClick debugger.
I think the visionClick is the best debugger I've ever found! BUT and 
its a BIG BUT. I purchase my visionClick just before WindRiver bought 
EST. And WindRiver has screwed it up! I run version 7.2 or close to 
that. I think WindRiver's first release was somewhere around 7.5 and 
not a user friendly. WindRiver supports visionClick/visionProbe for the 
PowerPC, but there is not much action around the 683xx family.
As for "bare metal" situations, the visionClick is the best. It has 
some hardware tests built in, memory tests, memory write tests, memory 
read ...
for very simple programs, you could get by without external RAM or ROM.
Pity that WindRiver messed up a very good thing.
If you can get a visionProbe and visionClick 7.2 (or about) license, 
then he'd be in business.

I would be interested in how you set up the gcc toolchain. In 
particular if you know how to set it up on a Mac OS X.

And for our Good friend Charlie, is there going to be a lead free or 
RoHS compliant version of the 68332 and 68376 available? And do you get 
to goto the Embedded Systems conferences? I really would have like to 
see you there. And I would have liked to have seen Mayer or Anderson 
there to kick some butt. The Freescale representatives didn't seem to 
be interested in talking to anyone but themselves. If I sound ticked, I 
am ... still.

P.S. I hope the 683xx family is  like the 8051, and lives forever.
