Welcome to the sandbox-daimler repository! This workspace contains a modular automotive software project for automotive ECUs (Electronic Control Units), focusing on embedded systems, safety, diagnostics, and compliance with industry standards. This project implements an AUTOSAR-compliant ECU. Below you'll find an interactive guide to the structure, technical details, and how to get started.

🔑 Technical Keywords

MCU / Microcontroller: - Platform in use: Infineon AURIX2G (TriCore tc33x) - Core: TriCore (tc33x variant) - Vendor: Infineon Technologies - Toolchain: TASKING VX-toolset for TriCore - Used for real-time control, safety, and diagnostics in automotive ECUs

ECU Functions and Main Functionalities: - This project concerns a single automotive ECU for occupant safety, diagnostics, and secure boot. - Main features include: - Crash detection, occupant protection, and airbag deployment - Boot process management, secure startup, and firmware integrity checks (Boot Manager) - Firmware flashing, update, and rollback (Bootloader, Updater) - Cryptographic operations, secure key storage, and authentication (HSM) - Vehicle diagnostics (UDS/KWP), error logging, and reporting - Communication over CAN, LIN, FlexRay - Functional safety (ISO 26262 compliance, ASIL levels) - Traceability, static analysis, and quality assurance

Product Details: - Automotive ECUs for occupant safety (airbag, seatbelt), secure boot, and diagnostics - Boot Manager (BM) is responsible for secure boot, firmware validation, and update coordination - Suppliers: Autoliv and others - Modules: Bootloader (FBL), HSM (Hardware Security Module), Boot Manager (BM), Updater modules

Norms & Protocols: - AUTOSAR (Automotive Open System Architecture) - CAN, LIN, FlexRay (vehicle communication protocols) - ISO 26262 (Functional Safety, ASIL levels) - UDS (ISO 14229), KWP (ISO 14230) for diagnostics - Security: HSM, cryptographic modules

Compliance & Quality: - Static analysis (QAC), code coverage, traceability - Integration/unit testing, safety-relevant requirements - Reports and metrics for quality assurance

Release & Traceability: - Binaries: ELF, HEX, MAP files - Test and coverage reports - Traceability to requirements and architecture

📁 Main Directory Structure

Architectures/: System and application architecture documentation (DOCX, diagrams, requirements)
Components/: Source code for application, bootloader (FBL), HSM, BM, updater modules, organized by supplier (Autoliv, etc.)
Methods/: Guides and how-tos for building, flashing, and development processes (DOCX)
Metrics/: Reports and scripts for static analysis (QAC), integration, and unit testing (Python, BAT, DOCX, XLSX)
Releases/: Compiled binaries (ELF, HEX), maps, and production deliverables for each release
Scripts/: Automation scripts for build, test, reporting, and configuration management (Python, BAT)
Tools/: Tooling for build environments, CANoe, Eclipse, Python, AUTOSAR, Doxygen, etc.

🚀 Getting Started

Explore the Architecture: See Architectures/Application/Description/ for design interface docs (DOCX, AUTOSAR ARXML)
Build & Flash: Follow the guides in Methods/HowTo/ (DOCX) for step-by-step instructions
Run Static Analysis: Use scripts in Metrics/Static_Analysis/ (e.g., run_qac.bat, PP4G_QAC_Analysis.py) for compliance and code quality
Check Releases: Find binaries and maps in Releases/R09.0_P91/ (ELF, HEX, MAP)
Automate Tasks: Leverage Python and batch scripts in Scripts/ for CI/CD, reporting, and more

🛠️ Key Technologies & Protocols

C/C++: Main embedded codebase (Components/)
Python: Automation and analysis scripts (Scripts/, Metrics/)
Batch Scripts: Windows automation for builds and reports AUTOSAR ARXML: Architecture and configuration (multiple locations in Components/)
CAN, LIN, FlexRay: Vehicle communication protocols
UDS, KWP: Diagnostic protocols
DOCX/XLSX: Documentation and metrics

📚 Documentation & Interactive Exploration

Design Docs: See the Architectures directory for interface specs, requirements, and diagrams. AUTOSAR Configs: See Components/ for ARXML configuration files
How-To Guides: Methods/HowTo/ (build, flash, compliance)
Test Reports: Metrics/Integration_Test/, Metrics/Unit_Test/ (DOCX)
Static Analysis: Metrics/Static_Analysis/ (QAC, compliance, safety)

🧩 Contributing

Add new components in the appropriate Components/ subfolder (C/C++, AUTOSAR)
Update or add scripts in Scripts/ for automation (Python, BAT)
Place new documentation in the relevant Architectures/ or Methods/ directory (DOCX, ARXML)

📢 Interactive Tips

Search for keywords like MCU, AUTOSAR, CAN, UDS, ISO, ASIL, HSM, FBL, BM, supplier, product, diagnostic, safety, compliance, traceability, test, coverage, report in the codebase for technical details.
Click on any folder above in VS Code to explore its contents.
Open DOCX/XLSX files directly in VS Code with the right extension.
Run Python scripts from the terminal for automation.
