Debugging early-stage bootloaders has historically been a fragmented experience, often requiring vendor-specific tools or customized logics. However, as the industry moves toward standardized boot flows, the UEFI Debug Support Protocol has emerged as a critical bridge.

In this talk, I will share the journey of implementing this protocol within U-Boot and LK (Little Kernel). We will explore the nuances of contributing to EDK2, and how these implementations simplify debugging the UEFI applications. Attendees will gain a deeper understanding of how standardized debug protocols can unify the development experience across different firmware ecosystems.
