Blackboard is the standard-bearer for student ID systems around the world. Their contactless cards serve as campus ID, building access, and point-of-sale accounts for meals and other services, and are rapidly replacing the old magnetic stripe systems. The cards and readers use a Windows Embedded CE-based platform. When Blackboard’s BSP provider learned that the systems would be responsible for keeping track of sensitive financial transactions, they recommended Datalight software to make certain that the system will function with bullet-proof reliability. To read more about our work with Blackboard, check out the full success story.

Recently we developed a sample project to demonstrate how to boot Linux from flash on an embedded system.  Booting NAND with a single (root) file system can be a challenge, even when using a NOR chip to initialize as this project did. So how did we do it? In order to simplify the process, we loaded our Datalight bootloader into the NOR flash and programmed the monitor that comes with the board to jump directly to it. So if you use the sample project with a Freescale i.MX31, a single command starts the loader and allows it to load the kernel and the initial RAM disk from flash managed by FlashFX Tera with Reliance Nitro. It will then read them into memory, jump to the kernel, and the kernel will start running code from the initial RAM disk which loads the FlashFX Tera and Reliance Nitro drivers into the kernel. Next, it mounts the flash as the root file system and the system is powered up and running. Within about ten seconds your i.MX31 is up and running with FlashFX Tera running the flash and Reliance Nitro running as the root file system. If you’d like to try it for yourself, we’ve included sample code for this project with our latest product release. In addition, our sample loader could just as easily be loaded into memory other ways.

We recently had the opportunity to work with Digital Payment to solve a NAND flash corruption issue by using the validation tools that come standard in FlashFX Pro. You’ve probably seen their shiny parking meters around town, including many remote locations that have no permanent power and no easy access to service. That’s why when Digital Payment learned of the reliability benefits of Reliance, they saw an opportunity to improve up-time and lower service costs. Reliability is just one of many reasons their parking meters are popular with parking lot owners and municipalities looking for dependable, user-friendly machines. Be sure to check out the full case study for more information about Digital Payment’s experience with FlashFX Pro and Reliance.

Customers tell us the performance and reliability benefits of our products are important competitive advantages for them. So with hundreds of Datalight customers shipping millions of products, why don’t you see more glowing reviews and fact-driven case studies on our website? As one top-tier consumer OEM recently told us, “If our competitors know that we use Datalight, they may use it too, and we don’t want to lose that advantage.” What a fantastic endorsement – Datalight is an ingredient of this customer’s “secret sauce!” Just last week an OEM building a metering product expressed reluctance to have us publish a case study. They were concerned competitors googling their name would find it and learn about the problem Datalight solved for them. One the one hand, it’s wonderful that our products are a factor in customers beating their competition; on the other hand it’s frustrating to not be able to tell the world about the role we’re playing in market leading devices. For now, our solution is to take the “Dragnet” approach and change the names to protect the innocent. And now you know the rest of the story: behind each example we use in marketing our products sits an organization driving fantastic innovation in the embedded industry with a real-world problem that Datalight solved.

Here are a few case studies that we are allowed to share:

Bothell, WA, – March 18, 2010 – Datalight announces support for Linux kernel versions up to 2.6.29 with new versions of FlashFX Tera, the file-system independent flash memory driver and Reliance Nitro, the highly-reliable, high-performance file system. FlashFX Tera version 1.2 offers out-of-the-box support for over 300 different flash memory parts from all the leading suppliers, expanding the choice for OEMs using flash memory. Linux is finding its way into more devices such as smart phones, automotive infotainment, and industrial equipment which require both responsiveness and 100% data reliability, by adding Reliance Nitro 1.2, OEMs can ensure rock-solid reliability of their systems without paying a performance penalty.

“Datalight continues to raise the standard in delivering advanced file system features for MontaVista Linux,” said Dean Misenhimer, Director of Marketing at MontaVista Software. “Our partnership provides our customers the option of a pre-integrated professional flash file system solution to speed their development of flash-based devices. This ultimately leads to faster time to market with superior performance and reliability.”

FlashFX Tera supports the full range of flash technologies including NAND, NOR, and MLC NAND flash in a single driver. Its patented wear-leveling and bad block management extend the useful life of devices using flash. While FlashFX Tera can be used with virtually any file system, pairing it with Reliance Nitro provides an optimized data storage software stack to simplify system development.

Reliance Nitro version 1.2 also adds support for extended file attributes. Most commonly used to designate file permissions, extended attributes are important to customers using special Linux distributions like SMACK. As data quantity and complexity in devices grows, extended file attributes can also be used for storing additional metadata (data about the data), such as digital rights information, GPS location or any information that makes finding and using the data easier. The ability of Reliance Nitro to serve as the root file system for Linux can simplify the data storage stack for these devices by allowing them to operate with a single file system.

“With the growth in adoption of Linux for data-intensive embedded devices, OEMs need a flash file system that better supports their reliability and performance requirements.” said Roy Sherrill, Datalight CEO. “By migrating our flagship products to Linux we’re filling that gap in the market with a robust, commercial-grade solution backed by our reputation for responsive, high-quality support.”

If you’re on LinkedIn, check out the Realtime Embedded Engineering Group for an interesting and often lively discussion of the issues facing our community. We particularly enjoyed reading the recent thread about the drivers included by hardware vendors being less than optimal for most flash parts. The consensus can be summed up in one blogger’s statement;

“What many silicon vendors refer to as a ‘driver’ is nothing more than the code left over by their inhouse hardware development team. This code typically exercises just a small subset of the device capabilities (or whatever they were working on last) and doesn’t even come close to meeting the definition (or spirit) of a general purpose device driver.”

We couldn’t have said it better ourselves. A lot of our time in developing our FlashFX family of flash memory drivers is spent ensuring completeness, reliability and portability to a wide variety of CPUs and operating systems.

Last week one of our customers sent the following evaluation report in an email to Datalight support staff:

“Right now we are in the process of testing the impact of Reliance Nitro in our application. Apparently, we noticed some boost in the performance:  faster write speed, significant speed increase of transaction point creation, faster read speed, and significantly faster directory read (we typically have 1000 files in the directory). So, in conclusion, the overall performance of the system is boosted quite significantly.”
