The execution jumps to a specialized, hardwired memory address segment called dmseg (Debug Memory Segment). ejtagd
Accessing system state without stopping the CPU (where supported). " Elara said
: While commonly associated with MIPS-based devices (like routers and early game consoles), it also provides support for various ARM-based systems. ejtagd
Overview of features like hardware breakpoints and Single Step mode.
"Lieutenant," Elara said, her voice raspy from days of disuse. "Run the cipher again."
: In its prime, it was a lightweight solution that didn't require the overhead of massive IDEs or expensive commercial debuggers. Drawbacks :
