Bothell, WA, May 14, 2010 --(PR.com
)-- Today Datalight unveiled a new whitepaper describing details of the company’s process for booting an embedded Linux system directly from NAND flash. Often considered problematic by OEMs in the past, booting from NAND is quickly becoming a requirement for smartphones and other embedded systems as consumers demand smaller, less expensive devices. As OEMs look for ways to save cost and space, many are eliminating the expensive and bulky NOR parts formerly used to boot the system. However NAND presents challenges in reliability and durability that call into question its suitability for booting a sophisticated operating system like Linux.
“We wrote this whitepaper to guide customers through one of the only reliable methods we’ve found for booting Linux from NAND,” said Ken Whitaker, Datalight Director of Engineering. “The sophisticated bad block management and wear-leveling in FlashFX Tera render NAND reliable for booting Linux.”
Datalight also recently released its Datalight Linux Bootloader, a sample project designed to further simplify the Linux bootstrapping process. It was originally built for the LogicPD MX31-lite platform and can be easily adapted for use on other hardware. The Datalight Linux Bootloader is included in new versions of Datalight Reliance Nitro, Datalight’s high performance reliable file system for Linux.
The whitepaper, entitled Bootstrapping Linux from NAND Flash with FlashFX Tera and Reliance Nitro, is available now from Datalight at http://www.datalight.com/resources/bootstrapping-linux-from-nand-flash
More about Datalight’s Flash File System for Linux
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.
The Reliance family of file system
s and FlashFX family of flash media managers comprise the Datalight flash file system solution. Reliance was designed from the ground up for high reliability applications. Dynamic Transaction Point™ technology gives developers full control over performance and data protection characteristics, protecting users from file system corruption, even after unexpected system interruption. Embedded applications can benefit from faster boot times that remain consistent for the life of the product, regardless of disk size. FlashFX™ Tera features pre-written support for over 300 flash parts, works with virtually any NAND controller, and features wear leveling, bad block management, and background compaction for unrivaled performance.
Datalight, Inc. headquartered just north of Seattle, Wash., develops technologies to enable risk-free mobile data. Datalight file system and device driver software ensures reliability, performance and flexibility, and is used worldwide on many of today’s most well-known devices.
