Medallion CPU development kit

Techsol has released the first development kit for their Medallion CPU modules. The four sqare inch, low-power Medallion modules are preloaded with Linux, device-drivers, graphics and communications software. (more…)

While attending the standards meeting for the Embedded Linux Consortium, it was pointed out to me that MontaVista has recently changed their policy of making the Journeyman CDs available. Those CDs, and ones like them, have brought the GNU cross-compiler to a lot of people. (more…)

Just because it's a TV-based device doesn't mean our finalists are catering to their inner couch potato. Using the Linux4.TV platform, they plan to interrogate suspects, run AI security systems in their homes, teach distance education classes and rock out in the home studio. (more…)

Part 2: Vendors and their products

Most of the “traditional” (if 12-18 months qualifies as “traditional”) embedded and real-time Linux players were present, plus a few newcomers. These included distribution providers, tools vendors, purveyors of middleware (browsers, GUIs, protocol stacks, etc.), chip makers, and board/system manufacturers . (more…)

Part 3: My favorite demo's

Now for the fun part! Here are some pictures — and brief descriptions — of some of the gadgets and demo's at the show that really caught my eye. (more…)

Part 4: ESC press release roundup

Finally, in case you missed any of the many announcements of products, services, and partnerships relating to Embedded Linux that accompanied the conference, here's a list of all the headlines . . .

• ELC proposes unified Embedded Linux platform spec
• (more…)

Embedded systems, even in their high-end variants, are resource constraint systems by desktop or server standards. At the same time, complexity of operations require many optimization strategies that were designed for server and desktop systems to be utilized in embedded systems as well. (more…)

During the development of embedded GNU/Linux projects a few main modes of operation have evolved. These modes will be briefly described in the next sections, showing the flexibility of embedded GNU/Linux. This flexibility is a product of the wide range of hardware Linux and embedded Linux has been deployed on — ranging from commodity… (more…)

The term compatibility has been widely misused, OS's claiming to be 'compatible' as such — without stating to what they are compatible. So first a clarification as to how this term is being used here. Compatibility between embedded OS and desktop development systems is one aspect here, this compatibility being on the hardware and… (more…)

Q5. How does OSware compare with other dual-OS, telecom-oriented stuff, such as products from Enea or Wind River? (more…)

Sorry; this article is no longer available online at IT-Director.com… (more…)

Q24. Can you characterize the state of embedded Linux, as a market and as a technology? (more…)

D. SUMMARY

At this point, it does not appear that any one approach can be all things to all realtime applications. It is therefore too early to pick a winner. Advocates of a given approach are therefore advised to concentrate their energy on implementations of their favorite approach, rather than engaging in flamewars with advocates of other… (more…)

C. LINUX REALTIME APPROACHES

The following general approaches to Linux realtime have been proposed, along with many variations on each of these themes:

1. non-CONFIG_PREEMPT
2. CONFIG_PREEMPT
3. CONFIG_PREEMPT_RT
4. Nested OS
5. (more…)
