Slim Bootloader (SBL) is an open source platform firmware to initialize platform hardware and boot an operating system through a payload. SBL provides a linear execution flow and relies on Intel® Firmware Support Package provided interfaces to accomplish platform initialization in a simple manner. This simplicity makes platform firmware enabling much easier by democratizing firmware development and encourages more participation from system software development community to cater to various IoT requirements. By taking a modular payload approach, SBL provides scalability to various different requirements by supporting different payloads. These value propositions provided by SBL - including open source with permissive licensing, simple execution flow, scalability and a rich set of features - will translate to lower TTM and TCO for the customers and make SBL an ideal choice for many IoT designs.
