ASIL D certification for PX5 FILE Embedded FAT File System
SGS-TÜV Saar has certified the embedded file system for the PX5 real time operating system (RTOS) to the highest levels of functional safety for automotive and medical applications..
PX5 FILE is a deeply embedded file presenting a native Linux file system API and has been certified to IEC 61508 SIL4, IEC 62304 Class C, ISO 26262 ASIL D, and EN 50128 SW-SIL4 functional safety standards.
Developers can now use the certification of the embedded file allocation table (FAT) file system in conjunction with their application software certification to build a reliable safety-certified device for the automotive, industrial and medical industries.
Developed by Bill Lamie, the founder of the Thread X RTOS, PX5 has specialised in a small code base of just 1kbyte to ease functional safety certification. 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.
This gives a faster path to certification, reduces product liability with improved quality and time to market.
PX5 was 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 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.
“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 complete suite of functional safety certifications for the PX5 RTOS is available today directly from PX5.
