News at a Glance...
OTTAWA, Canada, July 30, 2008 - QNX Software Systems today announced that it has published the source code for its entire suite of file systems.
Designed for high reliability and performance, QNX® file systems provide a standard POSIX interface for a wide variety of storage devices, including NAND and NOR flash memory; IDE, SATA, and SCSI hard drives; USB storage devices; CD and DVD optical drives; and RAM disks. The file system suite includes support for multiple industry formats, including FAT for Windows disk partitions, EXT2 for Linux disk partitions, and NFS/CIFS for network file access.
QNX has published the code as part of its hybrid software model, which enhances the productivity of embedded system developers by providing immediate, realtime access to the latest QNX code updates, bug fixes, and product developments.
Highlights of the source-code release include:
Unlike conventional file systems, QNX file systems run outside of the operating system kernel, as memory-protected applications. As a result, users can start, stop, or upgrade file systems on the fly, without having to reboot.
Moreover, a QNX-based embedded system can dynamically invoke the appropriate file system whenever the user inserts a USB stick, hard drive, iPod, or other storage device, and then dynamically unload the file system when the user removes the device. This capability simplifies the design of in-car infotainment units, industrial control systems, and other applications that must dynamically connect to a variety of media sources or streams.
Available for download
To download the source code for QNX file systems, QNX community members can visit Foundry27 (www.foundry27.com), the QNX developer portal, and click on the File Systems project.
The file systems join a growing list of QNX products now available in source form, including the QNX Neutrino® microkernel, QNX adaptive partitioning, QNX networking stacks, and board support packages for a large variety of embedded hardware.
Access to the QNX source code is free, but commercial deployments of QNX runtime components still require royalties, and commercial developers will continue to pay for QNX Momentics® development seats. However, noncommercial developers, academic faculty members, and qualified partners can download QNX development tools and runtime products at no charge.
