I completed "QNX Approved Training: Introduction to QNX Neutrino Architecture. " in September 2024, filed the certificate, and forgot it existed until today. QNX hashtag#Neutrino runs under a large share of the vehicles on the road. Digital cockpits, ADAS controllers, gateway ECUs, infotainment stacks. The microkernel design keeps drivers and protocol stacks out of kernel space, so a driver fault does not bring down the kernel. For anyone working on ISO/SAE 21434 and freedom from interference, that isolation property is where the threat model starts. The course covered the microkernel, synchronous message passing, resource managers, and the process model. Solid grounding for the automotive cybersecurity. Thanks to Dave Nickerson and QNX for running the session. hashtag#QNX #21434 hashtag#Neutrino hashtag#CAV hashtag#AutomotiveCybersecurity
