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)
- Rename bit_path -> bootloader_bit_path for clarity
- Rename elf_path -> bootloader_elf_path for clarity
- Split single bin_path into bootloader_bin_path (flash) and
firmware_bin_path (TFTP upload)
- Reorder Configuration panel: BIT -> ELF -> Bootloader BIN ->
Firmware BIN
- Update display names with file extensions and context labels
- Update all step references (Step 2 flash, Step 3 bootloader,
Step 4 TFTP) to use new field names
