      - ECU Reset (0x11 0x01)
      - Wait for ECU reboot
      - Verify software version updated
      - Generate flash report

  - name: flash_with_vflash
    steps:
      - Load vFlash project file (.vflash)
      - Configure CAN/DoIP interface
      - Set flash parameters (voltage monitoring, timing)
      - Register progress callback
      - Execute flash job
      - Monitor progress (percentage, transfer rate, ETA)
      - Handle errors with retry/rollback
      - Verify flash completion
      - Parse vFlash log file
      - Generate summary report

  - name: multi_ecu_flash
    steps:
      - Load flash manifest with ECU dependencies
      - Validate all ECUs are online
      - Determine flash order (bootloader dependencies)
      - For each ECU in order:
          - Execute standard flash procedure
          - Verify success before proceeding
      - Perform inter-ECU compatibility check
      - Test system functionality
      - Generate multi-ECU flash report

  - name: flash_recovery
    steps:
      - Detect flash failure (timeout, checksum error)
      - Attempt to re-establish communication
      - Check ECU bootloader status
      - If ECU responsive:
          - Retry flash from last successful block
      - If ECU unresponsive:
          - Attempt bootloader recovery mode
          - Flash bootloader if necessary
          - Flash application
      - If recovery fails:
          - Restore from backup if available
          - Report ECU requires service/replacement

communication:
  input_format: |
    Accept flash requests in structured format:
    - "Flash ECU with file /path/to/software.hex"
    - "Update Engine ECU to SW version 2.3.4"
    - JSON: {"action": "flash", "file": "app.vbf", "ecu": "engine", "verify": true}

  output_format: |
    Provide flash progress and results:
    - Real-time progress updates (percentage, rate, ETA)
    - Block-by-block transfer status
    - Error messages with recovery actions
    - Verification results
    - Comprehensive flash report (JSON/PDF)

error_handling:
  - Validate flash file before starting
  - Check ECU preconditions (voltage, ignition state)
  - Monitor voltage during flash (abort if out of range)
  - Handle TransferData errors with retry
  - Detect communication loss and attempt recovery
  - Implement timeout protection
  - Support flash abort and cleanup
  - Preserve flash backup for recovery
  - Log all errors with context for debugging

safety_measures:
  - Verify flash file checksum before programming
  - Check ECU compatibility (HW version, variant)
  - Monitor supply voltage (typically 11.5V - 14.5V)
  - Prevent interruption during critical phases
  - Implement rollback on verification failure
  - Validate bootloader compatibility before application flash
  - Enforce flash dependencies (bootloader version vs. application)
  - Protect against flash downgrade (anti-rollback counter)

best_practices:
  - Always backup existing flash before programming
  - Use Vector vFlash for production environments
  - Implement progress monitoring for user feedback
  - Verify flash integrity with multiple methods (checksum, fingerprint)
  - Test ECU functionality after flash
  - Generate detailed flash logs for traceability
  - Use compression to reduce flash time
  - Encrypt flash data for security
  - Maintain flash history database
  - Document all flash operations with justification
