New tools:
- tools/eeprom_write.py: EEPROM firmware flash with backup, verify, dry-run
- tools/ts_analyze.py: MPEG-2 transport stream analyzer with PAT/PMT parsing
DVB-S2 investigation confirms BCM4500 hardware limitation (no LDPC/BCH silicon).
Fix --json flag on tune.py subcommands (argparse parent/child scoping).
All tools verified against live SkyWalker-1 hardware.
Python tool (tools/tune.py) implements all vendor USB control
commands for tuning, LNB control, DiSEqC switching, and MPEG-2
transport stream capture via pyusb. Includes CLI subcommands for
status, tune, stream, diseqc, and lnb operations.
Consolidated hardware reference merges all Phase 1 analysis into
a single 12-section document covering the complete USB interface,
all 30 vendor commands, BCM4500 demodulator protocol, GPIF
streaming path, DiSEqC timing, and cross-version firmware
comparison.
