Detailed Explanation of ECU Network Management State Transitions: The Complete Mechanism from Sleep to Repeat Message State

2026-05-16 by boardor

In modern automotive electronic systems, dozens or even hundreds of ECUs (Electronic Control Units) communicate and coordinate through bus networks such as CAN, LIN, and FlexRay. To effectively manage the operational states of these ECUs and conserve vehicle battery power, AUTOSAR (Automotive Open System Architecture) has established a comprehensive network management protocol. Among these, the … Read more

Differences Between PRIMASK and BASEPRI in ARM

2026-05-09 by boardor

Recently, I discovered a phenomenon: in the AUTOSAR OS, if an interrupt occurs after task scheduling, the BASEPRI is used to control the enabling and disabling of interrupts. If it occurs before task scheduling, PRIMASK is used for control. This article introduces the differences between these two. 1. Differences <span>PRIMASK</span>: All or nothing switch. It … Read more

Why Automotive Embedded Engineers Must Understand AUTOSAR

2026-05-08 by boardor

Introduction Automotive electronics are transitioning from single ECU systems to centralized and highly interconnected architectures, leading to a dramatic increase in software scale and complexity. Early engineers only needed to master microcontrollers and low-level drivers, but today’s vehicles contain hundreds of ECUs and thousands of signal interactions. In this context, AUTOSAR is not just an … Read more
