The Yocto Project is a Linux Foundation collaborative open source project whose goal is to produce tools and processes that enable the creation of Linux distributions for embedded and IoT software that are independent of the underlying architecture of the embedded hardware. The project was announced by the Linux Foundation in 2010 and launched in March, 2011, in collaboration with 22 organizations, including OpenEmbedded.
The Yocto Project’s focus is on improving the software development process for embedded Linux distributions. The Yocto Project provides interoperable tools, metadata, and processes that enable the rapid, repeatable development of Linux-based embedded systems in which every aspect of the development process can be customized.
In October 2018, Arm Holdings partnered with Intel in order to share code for embedded systems through the Yocto Project.
The Unified Extensible Firmware Interface (UEFI) is a specification that defines a software interface between an operating system and platform firmware. UEFI replaces the Basic Input/Output System (BIOS) firmware interface originally present in all IBM PC-compatible personal computers, with most UEFI firmware implementations providing legacy support for BIOS services. UEFI can support remote diagnostics and repair of computers, even with no operating system installed.
Intel developed the original Extensible Firmware Interface (EFI) specification. Some of the EFI’s practices and data formats mirror those from Microsoft Windows. In 2005, UEFI deprecated EFI 1.10 (the final release of EFI). The Unified EFI Forum is the industry body that manages the UEFI specification.
Licensed provider for quality coreboot consulting services
coreboot, formerly known as LinuxBIOS, is a software project aimed at replacing proprietary firmware (BIOS or UEFI) found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system.
Since coreboot initializes the bare hardware, it must be ported to every chipset and motherboard that it supports. As a result, coreboot is available only for a limited number of hardware platforms and motherboard models.
One of the coreboot variants is Libreboot, a variant of coreboot aiming to be fully free of proprietary blobs.
The Linux Vendor Firmware Service is a secure portal that brings together firmware updates uploaded by renowned hardware vendors. The LVFS provides reliable firmware alongside with the detailed metadata for clients such as GNOME Software or fwupdmgr for controlling updates remotely through a terminal. There is no charge to vendors for the hosting or distribution of content and open source nature of this project provides additional value to the market with contributors from dozens of people from different companies. Consulting companies can offer advice on specific request implementation or help with custom plugins integration for fwupd allowing different protocols to be supported. We have experience in introducing new solutions (libflashrom API and fwupd flashrom plugin) into the current LVFS ecosystem and are not afraid to accept the most demanding firmware security challenges. We can become the maintainer of the firmware for your platform at any time!
