Add serial console, log export, and autoboot detection#6
Merged
Conversation
Serial Console (TUI + WebUI):
- Post-recovery interactive serial terminal in both UIs
- TUI: Input widget for commands, Ctrl-C sends 0x03 to device
- WebUI: text input + Send/Ctrl-C buttons, auto-scrolling output
Autoboot detection:
- Console read loop auto-detects "autoboot" in serial stream
and immediately sends Ctrl-C to interrupt U-Boot countdown
- Session-level break extended to 15s with autoboot keyword detection
- Fixed false-positive prompt matching on boot log substrings
(e.g. "hisilicon" in SPI probe function names)
- Verified on real hardware (defib_hi3516ev300_20260330_163650.log)
Log export:
- "Save Log" button in TUI (writes defib_{chip}_{timestamp}.log)
- "Save Log" button in WebUI (browser file download)
- Captures both recovery progress and serial console output
Bug fixes:
- TUI BadIdentifier crash: stage ids replace spaces with hyphens
- Duplicate log messages removed (Boot mode entered x2, Recovery complete x3)
- Handshake waits forever (no artificial timeout) across all 3 protocols
- "power-cycle the device now!" message on all protocols (Python + JS)
- Ctrl-C in TUI sends 0x03 to device instead of killing app
Tests:
- 6 autoboot regression tests from real hardware captures
- ProgressScreen rendering regression test
- *.log added to .gitignore
