Feature Description

Tracing allows an on-board log to be built of software execution where various points in the software a sample point can be saved with a time tag.

Rationale

Tracing (a.k.a autopsy) would provide a report of activities done in software before, say a reset. It would help identify/debug the causes of an issue in software.

Scope of Work

• Fw : Defining a trace port -- Done
• Svc :
  • Implement a trace file logger component to input traces and log to files -- Done
  • Create UTs -- Work in progress

consider adding state machine transitions, timer acquisition and release traces, and EVRS
to the category of traces that are automated. Also consider what a potential IO trace could look like. A ring buffer for IO is always requested for 1553 and recently M-Bus on Psyche. Presumably a limited IO trace of some could be packaged with the autopsy log and be useful.

Thanks Vivek. I'll discuss this with Tim and also go through the ones Eddie suggested to add to the list.
