# Analysis Methods
This document details the techniques used for analyzing TraceV3 files and CS35L27 firmware, including data sourcing, static and behavioral analysis, and anomaly correlation.
## Source Files
- logdata_LiveData.tracev3 (3.3 MB)
- 00000000000076e4.tracev3 (7.6 MB)
- 000000000000442d.tracev3 (870 KB)
- 00000000000012fa.tracev3 (643 KB)
- 0000000000000005.timesync (46 KB)
## Methods Summary
- Static analysis of firmware for code paths (I2C, GPIO, I2S)
- Runtime analysis for corresponding events/patterns in trace files
- Manual search for undocumented commands (0x81, 0xC7) and suspicious GPIO patterns
