PX5 has announced off-the-shelf functional safety certification of the PX5 FILE. Developers can now leverage the SGS-TÜV Saar certification of this embedded file allocation table (FAT) file system in conjunction with their application software certification to more quickly and cost effectively build a reliable safety-certified device for the automotive, industrial, and medical industries.
For developers of both safety-critical and non-safety-critical devices, the ultra-small certified file system offers a stable, reliable foundation built to industry best practices to support improved product reliability, security, quality, and time to market.
“Not only is functional safety top of mind for developers of safety-critical devices, but it impacts security since a device with functional safety vulnerabilities is easier to compromise,” said William Lamie, CEO of PX5. “This functional safety certification gives all embedded developers confidence in the safety, security, and certifiability of their application code. It’s also available without any compromise of core benefits, making PX5 RTOS and PX5 FILE the smallest, fastest, safest, and most secure in the industry.”
The PX5 FILE certifications were performed by SGS-TÜV Saar, a leading accredited, independent company for testing, auditing, verifying, and certifying embedded software for safety-related systems. The PX5 FILE is now the only deeply embedded file presenting a native Linux file system API that has achieved functional safety certification to the highest levels of the IEC 61508, IEC 62304, ISO 26262, and EN 50128 functional safety standards, specifically IEC 61508 SIL 4, IEC 62304 Class C, ISO 26262 ASIL D, and EN 50128 SW-SIL 4. Developers using the PX5 FILE can leverage the RTOS certification artifacts to save time and money during application certification.
Only certified RTOS and file system with industry standard APIs
As the first RTOS with a native POSIX pthread API, which is a standards-based API for multithreaded applications developed in C, the PX5 RTOS offers a familiar programming interface for embedded developers. The PX5 RTOS native pthreads implementation supports code portability and re-use, while providing a small memory footprint, full multithreading and hard real-time functionality. Similarly, PX5 FILE provides developers with the industry standard Linux file system API and with complete FAT 12/16/32/exFAT file system support, including fault-tolerant operation. Both PX5 RTOS and PX5 FILE include full development tool support, source code, and royalty-free licensing.
