Minimalistic or kernel plus a few packages would be ok.
Has anyone even attempted to put some subset of embedded
gentoo onto a coldfire?
I would suggest trying crossdev with the target:
m68k-softfloat-uclinux-uclibc
See http://www.gentoo.org/proj/en/base/embedded/handbook/?part=1&chap=3
If it's supported directly in the linux kernel, then you might be able
to just use
m68k-softfloat-linux-uclibc
but I'm not sure if that will work.
Use uclibc for sure (no mmu). uClibc also has a dynamic / shared object
loader as well, which was developed in recent years, so even on mmu-less
systems you can still use functions analogous to dlopen(), dlsym() (AFAIK).
Of course, whether or not the patchsets are incorporated is another
story, but since Coldfire is a pretty well ironed-out architecture, I'm
sure you won't have any issues.
Using portage as a build tool for mmu-less systems is a great idea in my
opinion. I would suggest using Ned's crossdev-wrappers as well (search
the list).
Yea, I still researching my options.
Also, the are continuing to beef up the
performance of the high end chips, in the coldfire
family.
When I figure out what I'm going to do, I'll drop
a note on the list, to let anyone comment on the
approach.
Thanks,
James
