Autosar Developer Interview Questions and Answers

Synchronous port interfaces require the sender and receiver to operate at the same time, while asynchronous port interfaces allow for independent operation.

• Synchronous port interfaces are used when the sender and receiver need to be synchronized in their operation.

• Asynchronous port interfaces are used when the sender and receiver can operate independently.

• Examples of synchronous port interfaces include SPI and I2C.

• Examples of asynchronous port interfaces include UART and USB.

Code flash is used to store program code while data flash is used to store data.

• Code flash is non-volatile memory used to store program code that is executed by the microcontroller.

• Data flash is also non-volatile memory used to store data that is retained even when power is removed.

• Code flash is typically larger in size than data flash.

• Examples of data stored in data flash include calibration data, configuration settings, and user data.

DCM submodules include DCM communication control, DCM diagnostic control, and DCM data transfer.

• DCM communication control manages communication between the diagnostic tester and the vehicle's electronic control units (ECUs).

• DCM diagnostic control handles diagnostic requests and responses between the tester and the ECUs.

• DCM data transfer manages the transfer of diagnostic data between the tester and the ECUs.

• Other submodules include DCM security access, DCM routine control, an...read more

Expected CTC is negotiable and open to discussion. Hybrid work is preferred.

• Expected CTC can vary based on experience and skills.

• Hybrid work is a preferred option as it allows for flexibility and work-life balance.

• The specifics of the hybrid work arrangement can be discussed during the interview process.

CDD module in Autosar stands for Complex Device Driver and is responsible for interfacing with complex hardware devices.

• CDD module handles communication with hardware devices that require complex processing.

• It abstracts the hardware-specific details and provides a standardized interface for upper layers.

• Examples of complex devices include Ethernet controllers, graphics processors, etc.

Different CAN states refer to the various operational modes of the Controller Area Network.

• CAN bus-off state occurs when the CAN controller is unable to participate in communication.

• CAN error-passive state occurs when the controller detects errors but is still able to communicate.

• CAN error-active state occurs when the controller is actively trying to recover from errors.

• CAN bus-on state is the normal operating state where the controller is actively participating in communicat...read more
