Build your own system firmware. This book helps you understand system firmware architecture and minimalistic design, and provides a specialized knowledge of firmware development. The book includes guidance on understanding the system firmware build procedure, integrating pieces of firmware and allowing configuration, updating system firmware, creating a development infrastructure for allowing multi-party collaboration in firmware development, and gaining advanced system firmware debugging knowledge.After reading the book you will be able to assume better control while developing your own firmware and know how to interact with native hardware while debugging. You will understand key principles for future firmware development using newer technology, and be ready for the introduction of modern safe programming languages for firmware development. Detailed system firmware development case studies using a futuristic approach cover:Future scalable system firmware development modelsTypes of firmware development (system firmware, device firmware, manageability firmware)Tools and their usage while creating system firmwareHow to build infrastructure for seamless firmware development using a multi-party development modelDebugging methodologies used during various phases of firmware product developmentSetting up key expectations for future firmware, including thinner firmware footprints and faster execution time, easier configuration, and increased transparent securityWhat You Will LearnUnderstand the system firmware working model of the futureGain knowledge to say goodbye to proprietary firmware for different types of firmware developmentKnow the different types of tools required for creating firmware source code before flashing the final image into the boot device of the embedded systemDevelop skills to understand the failure in firmware or in the system and prepare the debugging environment to root cause the defectsDiscern the platform minimal security requirementOptimize the system firmware boot time based on the target hardware requirementComprehend the product development cycle using open source firmware developmentWho This Book Is For Embedded firmware and software engineers migrating the product development from closed source firmware to open source firmware for product adaptation needs as well as engineers working for open source firmware development. A secondary audience includes engineers working on various bootloaders such as open source firmware, UEFI, and Slim Bootloader development, as well as undergraduate and graduate students working on developing firmware skill sets.
