AUTOSAR Memory Stack is a collection of software modules that stores, clears and manages Memory. It consists of the following modules Memory Abstraction Interface : MemIf abstracts from the number of underlying FEE or EA modules and provide upper layers with a virtual segmentation on uniform linear address space. …

Collection of Automotive sensor information from internet, Water in Fuel Sensor WiF sensor indicates the presence of water in the fuel. It is installed in the fuel filter and when the water level in the water separator reaches the warning level, the Wif sends an electrical signal to the ECU…

XCP (or) “Universal Measurement and Calibration Protocol” is a network protocol originating from ASAM for connecting measurement/calibration systems to electronic control units, ECUs. It enables read and write access to variables and memory contents of micro-controller systems at run-time. To achieve independence from a specific physical transport layer, XCP was…

Below are some of the C rules mandated by AUTOSAR Declaration There should not be more than one declaration per line. Eg uint8 blockIndex, lastBlock; /*violation*/ Brackets Brackets shall always be used in complex expressions even if the C priority rules do not necessarily demand this for operators. This also…

EcuM is one of the first module initialised, immediately after any Ecu Reset and responsible for initialising all other BSW modules including OS and RTE. The list of modules and order of initialisation is configurable in EcuM.​ EcuM manages various possible states (like Startup, Run, Sleep,Shutdown) that an Ecu can…

Here are some basic characteristics that AUTOSAR OS should have Should be configured statically(meaning the priority and properties of the tasks , stack size . etc.. are fixed at build time) Real time responsiveness provides priority based scheduling provides protection features like memory , timing protection etc.. should run on…

ECU hardware needs to be tested to ensure safety of the vehicle and consequently ensure compliance to ISO26262. These tests are comparable with the power on self test (POST) which we have in our PCs. However unlike POST HW tests in AUTOSAR can run in startup, normal execution or shutdown…

In this article , we will see about the features provided by AUTOSAR to be compliant to ISO26262. ISO26262 is a safety standard for on-road vehicles . In layman terms, ISO26262 tries to reduce the probability of vehicle accidents which could potentially injure or kill driver/passengers arising out of fault…

ADC Driver configuration: Many configuration items are available as per AUTOSAR spec to configure the ADC driver. These items are grouped together as containers. Important containers and their configuration items are listed below. Adcgeneral: This container contains the general configuration of the ADC Driver AdcDevErrorDetect: Switches the Development Error Detection…
