BlackBerry QNX announces safety-certified filesystem

BlackBerry has strengthened its QNX OS for Safety with the addition of a unique POSIX-compliant, ISO 26262 certified, integrity checking filesystem to provide OEMs and other embedded software suppliers an additional layer of validation when building safety-critical systems. Certified to ISO 26262 ASIL B, the automotive industry’s functional safety standard, QNX Filesystem for Safety verifies the integrity of all filesystem contents at runtime, enabling embedded software developers to detect if any corruption has taken place and to take all necessary actions to maintain the safety of the system. If, for instance, a file that ran a safety-critical function like collision avoidance or object detection got corrupted before running or was loaded with incorrect configuration data, the issue might not even be noticed until it was needed in a crucial moment, potentially leading to a dangerous or even fatal situation. QNX Filesystem for Safety guards against this, validating all data and performance parameters that safety-critical systems are built and run on.
