System Firmware (eBook)

Find the right bootloader solution or combination of firmware required to boot a platform considering its security, product features, and optimized boot solutions. This book covers system boot firmware, focusing on real-world firmware migration from closed source to open source adaptation.

The book provides an architectural overview of popular boot firmware. This includes both closed sourced and/or open source in nature, such as Unified Extensible Firmware Interface (UEFI), coreboot, and Slim Bootloader and their applicable market segments based on product development and deployment requirements.

Traditional system firmware is often complex and closed sourced whereas modern firmware is still a kind of hybrid between closed and open source. But what might a future firmware model look like? The most simplistic boot firmware solution uses open source firmware development. This book helps you decide how to choose the right boot firmware for your products and develop your own boot firmware using open source. Coverage includes:

• Why open source firmware is used over closed source
• The pros and cons of closed and open source firmware
• A hybrid work model: for faster bring-up activity using closed source, binary integrated with open source firmware

What You Will Learn

• Understand the architecture of standard and popular boot firmware
• Pick the correct bootloader for your required target hardware
• Design a hybrid workflow model for the latest chipset platform
• Understand popular payload architectures and offerings for embedded systems
• Select the right payload for your bootloader solution to boot to the operating system
• Optimize the system firmware boot time based on your target hardware requirement
• Know the product development cycle using open source firmware development

Who 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.
