**JTAG check**: Switch from Vivado to xsct
- xsct is already proven to work (JTAG reboot succeeds)
- Much lighter than Vivado (no GUI infrastructure / open_hw_manager)
- Uses -eval inline TCL: connect; targets; disconnect; quit
- Removes dead tempfile/Path/os imports
**Windows COM port**: Add normalize_port() to serial_monitor.py
- COM ports >= 10 require NT namespace prefix (\.\COM11)
- Without it: PermissionError(13, '拒绝访问。')
- Applied at all 7 call sites: serial_monitor (5), reboot_manager, widgets
Tool discovery:
- On Windows, scan .bat files in addition to .exe
(Xilinx Windows tools use .bat wrappers, not .exe)
- Prefer .exe over .bat when both exist (same version dir)
Environment setup:
- _find_settings_script(): walk up from bin/ to find settings64.sh/.bat
- build_tool_command(): wrap Linux tool invocation with 'source settings64.sh'
Windows .bat wrappers handle env internally, no extra wrapping needed
- reboot_manager.py now uses build_tool_command() for proper env
Example output (Linux):
build_tool_command('/data/xilinx/Vitis/2023.2/bin/xsct', 'script.tcl')
→ ['bash', '-c', 'source .../settings64.sh && .../xsct script.tcl']
rst -system inherently resumes ARM execution on Zynq.
The subsequent 'con' command fails with 'Already running'
because the core is already executing after system reset.
Fix: wrap 'con' in 'catch {}' — if core is already running
the error is silently caught; if stopped, con resumes it.
xsct exits 0 (success) in both cases.
Config:
- Add boot_wait_delay (default 10s) for post-reboot wait time
Layout:
- Restore row weights for proportional scaling when maximized
- CTkScrollableFrame handles overflow when window is small
Step 3:
- Log xsct/vivado tool output (last 20 lines per result)
for detailed diagnostics
Step 4:
- UART boot wait: monitor for IP/version via UART after reboot
- If UART unavailable, fall back to config.boot_wait_delay
- Reduces unnecessary wait time when boot is detected early
Serial:
- Real-time port validation on selection change (CTkComboBox command)
- Persistent UART unavailable warning until valid port selected
- Auto-restart UART monitor on port switch
- Graceful cross-platform handling
