Scope
We capture trace windows around modem bursts, correlate with thread ready queues, and recommend priority ceilings without starving maintenance tasks.
Included analyses
- IRQ budget spreadsheet tied to modem AT windows
- Thread readiness heatmap for 48-hour soak
- Deferred work queue sizing experiment plan
- Mutex audit with priority inheritance toggles
- Power-manager handshake review
- Release notes template for RTOS tuning deltas
Outcomes you can publish internally
- Evidence-backed priority table
- Safer defaults for maintenance threads
- Trace recipe your team can replay monthly

FAQ
Which tracing backends?
SEGGER SystemView, Percepio Tracealyzer, or vendor ITM—whatever you already license.
Can you sign an NDA?
Yes, mutual NDA precedes log exchange.
Limitations?
We do not certify safety compliance; we supply measurements and recommendations only.
Experience notes
“Clear read on why our MQTT thread starved during OTA.”
“Still tuning priorities, but the RTOS queue fairness brief gave us a shared vocabulary.”
