Wind River Completes Embedded Linux Metamorphosis 107

Posted by Hemos from the going-to-the-tiny dept.
An anonymous reader writes "Embedded software powerhouse Wind River's metamorphosis into an embedded Linux vendor appears to be complete. The company will announce today that it is shipping a pre-release version of its first embedded Linux distribution, and that it has already delivered 1,000 "developer seats" for the Carrier Grade Linux 2.0 compliant software."

      actually a little more than that needs to be said.

      if they have a solid RT linux product for their embedded offerings then they might be able to tie things up and run with it. If it's a general purpose embedded linux then they just wasted a HUGE amount of time.

      A slightly good linux person with 5 days of time and a copy of building embedded linux systems can throw down a good fast small embedded linux distro that will make ANYTHING that a commercial distro look silly and horribly overpriced.

      We looked at embedded linux distros 4 years ago here and settled on a roll your own.

      we have a better product that we KNOW works for us, is easily customized and is certianly much smaller than anything we could buy.

        Same here.

        I joined a team working on functionality running on an embedded Linux distribution about a year ago. After doing major cleanup in the sources, including an upgrade to the newest release of the embedded distribution; I started looking under the hood.

        Several portions of the distributions were replaced by busybox, uclibc and a gcc-3.4 based toolchain. In the process, we built our own Perl based build system (with CVS): we check in/out only the modified files (basically only platform files) and use the original tarballs (tar xkfj).

        As a result, we were able to decrease the embedded compressed filesystem to less than 33%, our code is much closer to the upstream developments (e.g. for network drivers, this can be an issue) and our system is modular and flexible. (btw, size does matter in production and for field upgrades): smaller, faster and cleaner...

        I am currently in the process of cleaning up the platform dependent files for release and inclusion into the upstream projects (hopefully they get accepted).

        We moved away and have not looked back and saved over 25,000 Euros per year (and rising) in the process. Yes, the embedded distributions are terribly expensive. If you have money to spare, consider hiring teams from the companies selling expertise and releasing the code like http://www.denx.de/ [www.denx.de], http://www.codepoet.org/ [codepoet.org], http://www.pengutronix.de/ [pengutronix.de], http://www.mind.be/ [www.mind.be], ...

        That was the old regime. I worked at Wind River in 2002, when they were in dire straits, and met the then-CEO, Tom St. Denis, who was firmly anti-Linux--to the point that, if someone in a meeting mentioned Linux, he would just ignore you, as if you hadn't spoken. (Wasn't just me--other people told me the same thing happened to them.) A while after that, St Denis got fired (okay, "left the company to pursue other opportunities") and the new CEO (Ken Klein) is very pro-Linux. I was at a meeting in December where he spoke enthusiastically about open source, and reminded us that the company wants to maintain a "good neighbor policy" (i.e., let developers devote company time to open source projects.) I think this attitude is the single biggest difference between the struggling Wind River of 2002 and the stable Wind River of 2005.

      No, it's not. I used to think Linux would be all that and a bag of chips for embedded systems, but working with it dissuaded me of that fantasy.

      It doesn't have a nanosecond clock, and there aren't any patches available for the 2.6 kernel.

      There's no real-time support without patching the living hell out of your kernel, and then possibly running a mini-kernel underneath.

      And, while not strictly relevant, it also doesn't have PPS API support built-in, which means you're also in for a wonderful round of patching to get something even remotely workable for synchronized systems. There's still no hardpps() support, so even that's just a maybe.

      If you want something suitable for critical, real-time embedded systems, you'd have to patch the kernel so much that it'd barely look like Linux at the end.
