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)
