U-Boot Concept now supports the EFI Boot Graphics Resource Table (BGRT) feature. This enhancement allows for a more seamless and branded boot experience on devices that use EFI_LOADER, i.e. the Unified Extensible Firmware Interface (UEFI).

What is BGRT?

The BGRT is a table in the ACPI (Advanced Configuration and Power Interface) that allows the firmware to pass a logo or image to the operating system during the boot process. This means that instead of a generic boot screen, users can be greeted with a custom logo, such as a company or product brand. This creates a more professional and polished user experience.

Why is this important for U-Boot?

By supporting BGRT, U-Boot can now provide a more consistent and visually appealing boot experience on a wider range of devices, particularly those running operating systems like Windows or Linux that support UEFI. This is especially valuable in embedded systems and custom hardware where branding and a unique user experience are important.

This new feature further solidifies U-Boot’s position as a leading bootloader for a diverse range of applications, from embedded systems to servers. It demonstrates the community’s commitment to keeping U-Boot up-to-date with the latest industry standards and providing developers with the tools they need to create modern and user-friendly products.

Welcome to the new official blog for Das U-Boot! For over two decades, the U-Boot mailing list has been the vibrant hub of our development discussions. While the mailing list remains our primary channel for patches and technical conversations, this blog will serve as a new platform to share deeper insights, project news, and community stories in a more accessible format.

As of mid-2025, U-Boot is more critical to the embedded ecosystem than ever. Our development is thriving, with robust support spanning a vast array of architectures from ARM and x86 to the rapidly expanding world of RISC-V. U-Boot provides a flexible, powerful foundation for countless products in the industrial, automotive and consumer-electronics spaces, incorporating modern standards like FIT, EFI and Firmware Handoff to meet today’s demanding security and interoperability requirements.

This blog is a community platform, and we need your voice to make it a success. We invite developers, maintainers, and users to contribute posts. Have you recently ported U-Boot to a novel board? Do you have a technical deep-dive on a specific subsystem you’d like to share? Or perhaps a case study on how U-Boot solved a unique challenge in your project?

If you have an idea for a post, please email the admin to get a login for this site. We’re excited to build this resource with you.

Happy hacking!
