Robert Day, VP of marketing, said: “LynxOS-178 2.2.4 has been developed to fully meet the requirements of DO-178C – the latest standard used by the FAA to certify commercial software-based aviation systems – while maintaining the open standards support such as FACE and POSIX to allow true software portability, even for safety-critical applications”.
LynxOS-178 2.2.4 offers full native POSIX.1 support, including the services specified by POSIX 1.b (real-time extensions) and POSIX 1.c (threads extensions). This open-standards support allows safety software applications to be ported from one system to another and facilitates the migration of applications written for other POSIX OSes, such as Linux. LynxOS-178 2.2.4 supports the latest FACE 2.1 standard, providing APIs for the Security, Safety Basic and Safety Extended profiles. LynxOS-178 2.2.4 is complemented by the Lynx Certifiable Stack (LCS), a DO-178C certifiable TCP/IP protocol stack, for safety certified networking components.
Released initially for a range of QorIQ processors from NXP, Lynx is also porting the OS to Intel x86 and ARM platforms.
