Firmware and Runtime Correlation Summary
All data in this report is strictly based on direct observation from both static firmware analysis and runtime TraceV3 log review.
Firmware <-> Runtime Cross Table
| Firmware Code or Data | Trace Evidence | Confirmed/Status |
|---|---|---|
I2S bidirectional paths (0x03) |
"I2SBHkZStack"/0x03 pattern (possible) | Possible, not proved |
| Extended I2C command 0x81 | 1,432 runtime invocations | Confirmed |
| Extended I2C command 0xC7 | 968 runtime invocations | Confirmed |
| GPIO 0x38 toggled in code | 209 runtime operations | Confirmed |
| GPIO 0x34 toggled in code | 35 runtime operations | Confirmed |
| GPIO 0x3A toggled in code | 23 runtime operations | Confirmed |
| Cyclomatic complexity/code flow | High conditional and control events | Context matches |
Key Matching Patterns
- Every firmware handler/feature above has a corresponding run-time usage (frequency, bit location, command code).
- Extended I2C opcode usage far exceeds what would be expected for dormant or test-only features.
Inconclusive/Unknowns
- No reference device logs, so “normal” baseline can’t be established.
- Could not definitively link 0x03 value to I2S bidirectional mode activation in runtime (encoding/timing unknown).
- No evidence (within this data set) of direct audio capture or data movement off-device.
