AUTOSAR OS essentials: Master the core of automotive real-time systems, from its OSEK/VDX heritage to its critical role in modern ECU projects.

Gain deep insights into runtime behavior, covering task scheduling (Basic vs. Extended), ISR categories, resource priorities, and synchronization.

Learn to implement time-driven systems using events, alarms, counters, and synchronized schedule tables.

Gain practical experience: ~70% of the course is dedicated to configuration labs using vendor-neutral ARXML and industry-standard patterns.

How this helps: Confidently architect and troubleshoot tasking, timing, and protection mechanisms in complex production projects.

Who it’s for: Embedded and automotive engineers looking to master the AUTOSAR OS stack and multicore operation.

The training also includes advanced coverage of Debugging Hooks, Multicore IOC, and Memory/Timing Protection features.

Curriculum

Fundamentals

What AUTOSAR OS provides; relationship to RTE and BSW
OSEK/VDX heritage and terminology; OS objects taxonomy
Scalability Classes (SC1–SC4) vs. OSEK Conformance Classes (BCC/ECC) — when each matters

Tasks and ISRs

Basic vs. Extended tasks; activation, states, priorities; preemptive vs. non-preemptive
ISRs Category 1/2; context and nesting; stack considerations
Hooks: StartupHook/ShutdownHook, PreTaskHook/PostTaskHook, ErrorHook

Resources, critical sections and synchronization

Resources and internal resource; Priority Ceiling Protocol and deadlock avoidance
Spinlocks for multicore; interrupt control and critical sections
Trusted functions (overview)

Events, alarms and counters

Events for Extended tasks (SetEvent/WaitEvent/ClearEvent) and state transitions
Alarms tied to counters; relative vs. absolute; auto-start and cyclic alarms
Counters, tick rate and time base selection

Schedule tables and time management

Schedule tables vs. alarms; expiry points and actions (ActivateTask, SetEvent, etc.)
Synchronizing schedule tables; next expiry, repeating and explicit synchronization
Using schedule tables for periodic control

Protection and multicore operation

Timing protection (budgets, overruns, protection violations)
Memory protection (OS-Applications, MPU regions, supervisor/user modes)
Inter-OS-Application Communication (IOC)
Core-aware configuration and distribution of tasks

Configuration, generation and troubleshooting

ARXML configuration overview; mapping tasks, ISRs, resources, events and schedule tables
Code generation and integration; OS startup sequence
Troubleshooting patterns: missed activations, priority inversions, protection violations; tracing tips
