About this book:

This book provides a comprehensive guide to best practices in embedded software and firmware development for hardware startups, emphasizing reliability, security, and scalability. It meticulously covers foundational firmware architecture, including modular design, Real-Time Operating Systems (RTOS), and robust state machines, ensuring predictable and maintainable systems. The text also delves into critical aspects like communication protocols, hardware interfaces, and extensive testing methodologies, from unit and integration to system-level validation, including Hardware-in-the-Loop (HIL) and automated analysis.

Beyond core development, the book places a strong emphasis on critical operational and security considerations essential for connected devices. It details strategies for secure boot, trusted execution, and threat modeling, ensuring security-by-design from the ground up. Over-the-Air (OTA) updates are thoroughly explored, covering architectures like dual-bank partitioning for safe rollbacks, and the crucial role of firmware signing, encryption, and cloud-based update management. Practical advice on DevOps integration, version control, code review, managing technical debt, supply chain security, and building resilient cross-functional teams rounds out this indispensable resource for building future-proof embedded products that scale with a startup's ambitions.

What You'll Find Inside:

• Learn foundational firmware architecture principles for scalability, including Hardware Abstraction Layers (HAL), Board Support Packages (BSP), and layered design, to ensure modularity and ease of maintenance.
• Master the use of Real-Time Operating Systems (RTOS) and state machines to manage concurrent operations, achieve determinism, and design predictable system behaviors for complex embedded applications.
• Understand comprehensive testing strategies, including unit, integration, system, and Hardware-in-the-Loop (HIL) testing, alongside static and dynamic code analysis, to build robust and reliable embedded firmware.
• Implement secure boot, trusted execution environments, and robust key management practices, along with threat modeling and secure communication protocols, to protect devices from tampering and cyber threats.
• Develop effective strategies for Over-the-Air (OTA) updates, including dual-bank architectures, safe rollback mechanisms, and cloud-based fleet management, ensuring continuous improvement and resilience for deployed products.
