Allows the software to read or write directly to system RAM and flash memory addresses without needing the CPU to execute instructions.

EJTAG is often considered a "hacker’s playground" because it allows for total control over an embedded system, bypassing software-level security restrictions. 1. Unbricking Devices ejtagd

Developing for EJTAG-enabled chips usually requires a combination of a hardware "dongle" and a software debugger: EJTAG: аттракцион для хакеров - Habr Allows the software to read or write directly

The daemon can abruptly freeze the CPU mid-clock cycle, allowing engineers to view registers exactly as they sit in silicon. ejtagd

The power of EJTAG lies in its well-defined architecture, which is composed of several key hardware components integrated into the CPU:
