CTkToplevel grab_set() fails when called before the window is
fully realized on screen. Defer to after(50ms) so the window
has time to become viewable.
Replace 'Read Serial' button with 'Open UART' that opens a new
UART Monitor window (CTkToplevel) with:
- Title bar with status indicator (● connecting/ready/monitoring/error)
- Port info display + Start/Stop/Clear buttons
- Large scrollable log area (CTkTextbox) with monospace font
- Auto-scroll to bottom, line counter in status bar
- Boot info parsing (IP, version) shown as [BOOT] prefix
- Background serial monitoring via UartMonitor class
UART unavailable handling:
- On init, tries to open serial port in background thread
- If port can't open → shows 'UART 不可用' state with error message
- If port opens → shows 'Ready', user clicks Start to begin monitoring
Window features:
- Modal (grab_set) — focus stays on monitor window
- Clean up UartMonitor on close (WM_DELETE_WINDOW handler)
- Thread-safe UI updates via after(0, ...)
- Reuses existing UartMonitor from serial_monitor.py
Configuration panel now has a 'Xilinx Kit:' row at the top with:
- Entry field showing current path
- [Browse] button using system directory dialog (cross-platform)
- Select root directory (e.g. /data/xilinx or C:/Xilinx)
vitis_checker.py now scans xilinx_root subdirectories:
1. System PATH (shutil.which) — works on all platforms
2. Legacy vitis_path/bin
3. xilinx_root/Vitis/*/bin and Vivado/*/bin (all versions, newest first)
4. Common install paths (Windows: C:/Xilinx, Linux: /data/xilinx, /opt/xilinx)
Multi-version: scans all version directories under Vitis/ and Vivado/,
picks the newest version for each tool.
Config: xilinx_path replaces vitis_path (backward compat kept)
1. SubStepFrame defaults to expanded (▼), not collapsed
2. erase_all checkbox has command=_on_erase_toggle → immediate config update
3. _deferred_init runs _check_vitis/_refresh_ports in background thread
Fixes UI freeze during startup (subprocess.run for tool versions)
4. Sub-step colors now match StepHeader:
- pending: gray ACCENT_PENDING (#888888)
- running: blue CIRCLE_RUNNING (#0078D4) with pulse animation
- complete: green ACCENT_COMPLETE (#107C10)
- error: red ACCENT_ERROR (#D13438)
- Running sub-step pulses between light/dark blue like StepHeader
Based on real hardware timing data from XC7Z100 testing:
UART Monitoring:
- New UartMonitor class in serial_monitor.py: background thread reads
serial output continuously, parses for IP/version/boot messages
- GUI starts monitor when workflow runs, stops on completion/close
- Serial lines flow into log display in real time
Step Timing:
- New step_timeouts config (experience × 2):
check_env:30s flash_erase:120s flash_program:600s
bitstream:60s elf_download:60s tftp_reboot:120s
- GUI shows estimated timeout before each step
- Shows actual elapsed time after each step completes
- All subprocess calls now use config-driven timeouts
Non-blocking Output:
- New subprocess_utils.py: run_streaming() uses Popen + threaded
stdout/stderr readers, parses WARNING/ERROR/progress% in real time
- flash_programmer and bitstream_programmer use it
- Callbacks receive categorized events (out/err/warn/error/progress/done)
