AMI Debug for EFI 1.0

AMI Debug for EFI is a professional firmware-debugging tool focused on the EFI/UEFI environment. It helps platform and BIOS/firmware engineers diagnose issues from the earliest boot phases (SEC and PEI) through DXE and into UEFI drivers and applications. The tool exposes low-level system state, enabling efficient bring-up, faster root-cause analysis, and improved firmware reliability.

Key capabilities include:

• Breakpoints, single-step execution, and inspection of memory, I/O, and CPU registers
• Visibility into UEFI data structures such as HOBs, PPIs, protocols, and handles
• Support for common debug transports (for example, serial/UART and USB debug, depending on platform support)
• Symbol-aware debugging with integration into typical toolchains and build outputs
• Non-intrusive tracing that reduces the need for ad hoc instrumentation

Typical use requires a target build with debug symbols and board-level enablement for the chosen debug transport. While often used with EDK II- and Aptio-based firmware, applicability depends on the platform’s firmware configuration and available interfaces.
