I am looking for a good Linux distribution for an embedded system. We
a small budget, so costs does make sense. Better supports are also
appreciated. Could anybody please recommend one or a few candidates?
BTW, how is ¦ÌClinux 2.6.26? How is Wind River Linux 3.0? Which one is
better in your opinion? Any other good candidate?
Thank you in advance.
BTW, I heard 90% of the embedded Linux developers built their own OS for
free, instead of purchasing a commercial distribution from Wind River or
LynuxWork or else. Is it true? Our product is not hobby work any more, and
we are serious about the business. Is it a good choice for us to go with a
free Linux or a commercial distribution?
At my work WindRiver did a pretty convincing presentation about their
Linux offering. The management types were keen to use it but there
were 2 reasons that we decided no to go with it. The first was we'd
already gone down the path of rolling our own and couldn't really
figure out what we were going to gain by handing over money. The
second was we would be locked into using the full workbench (based on
eclipse) suite of tools and the windriver build system.
We didn't like the tools because we'd had some bad experiences with
the eclipse C indexer dieing horribly when pointed at a massive
codebase (like the Linux kernel). We'd also built up a nice make
system that we'd essentially have to re-do.
My preference would be the roll your own approach using code from
kernel.org and something like buildroot (http://
buildroot.uclibc.org/) or openembedded (http://openembedded.org/) for
your make system and userland apps.
Having said that if you are starting from scratch and have got the
cash WindRiver have got the tools and training infrastructure that may
save you some time.
Very informative. I think it is the way to go!
