Embedded Debugging and Instrumentation

Embedded debugging and instrumentation expose what firmware and hardware are doing inside a target device. Debug probes, breakpoints, trace hardware, and deliberate event records help you inspect failures that ordinary application logs cannot explain.

Embedded Debugging and Instrumentation

Embedded debugging is the practice of observing and controlling software on a target device from a separate host computer. Instrumentation adds deliberate measurements or event records to the firmware. Together, they make otherwise hidden processor state, timing, peripheral activity, and failure context available for analysis.

An embedded target often cannot run a full debugger itself. It may have little memory, no display, no filesystem, and strict timing requirements. The common arrangement therefore separates the work across several components:

                                              target debug hardware
                                                          │
                                      core, memory, flash, trace sources

The host debugger maps machine addresses back to functions, source lines, and variables by reading the unstripped executable and its debug information. A debug server translates debugger requests into operations understood by the probe. The probe drives the electrical debug transport. On the target, on-chip debug hardware supplies run control, register access, memory access, breakpoints, watchpoints, and optional trace.
