Re: Creating a gentoo based system for embedded
[In reply to]
I know and I agree with every one this is possible to generate this system
, BUT the main problem is in the possibility to make evolve this system and
the tools to create and maintain it .(I think this is the awaited added
Gentoo seems a good choice , because you may be able to upgrade your system.
I know there are tools that have been developped like catalyst. Is it a good
choice in this case ?
Building an embedded system from scratch will work, but you are faced to
evolution problem.I agree that embedded system must not evolve every day, but
every year our customers are requestings for new features in there machines.
we should be able to add these new features with the today 's tools and
technologies (ex : wifi was not really implemented fin industry ew years
Thanks for your replies.
I will try catalyst and will give you my feedback .
