JTAG-Based UEFI Debug and Trace - Webinar

The IEEE Joint Test Action Group (JTAG) standards define debug, test and hardware validation technologies that are ingrained within much of today’s commercial silicon. In particular, platform debug is enabled by JTAG-based run-control (for example: halt, go, set breakpoint, single-step) and trace (for example: instruction trace, real-time UEFI “tool-hosted printf” message trace). On many systems, JTAG-based debugging is typically available from the very first instruction after CPU reset, allowing it to assist with development of early boot software that runs before any device or bus is initialized.

This presentation will provide examples on the utility of JTAG-based UEFI debug and trace on x86 platforms.
