## Device Detection Problem - SOLVED ✅

### The Challenge
When multiple development boards are connected:
- Need to identify which `/dev/cu.usbmodem*` belongs to which board
- Can't hardcode ports (they change)
- Manual identification doesn't scale

### The Solution
**Two-tiered device detection:**

1. **Hardware Detection:**
   - Use `esptool` to identify ESP32 boards
   - Use `JLinkExe` to identify J-Link devices
   - Use `probe-rs` to identify probe-rs compatible boards
   - Use USB vendor/product IDs as fallback

2. **Automation Integration:**
   ```bash
   # Old way (manual)
   eabctl flash --port /dev/cu.usbmodem101 examples/esp32c6-debug-full

   # New way (automatic)
   PORT=$(python3 scripts/detect_devices.py --device esp32c6 --port-only)
   eabctl flash --port $PORT examples/esp32c6-debug-full

   # Or in scripts
   ESP32_PORT=$(python3 scripts/detect_devices.py --device esp32c6 --port-only)
   NRF_PORT=$(python3 scripts/detect_devices.py --device nrf5340 --port-only)
   ```

3. **Persistent Device Mapping:**
   ```bash
   # Generate device map
   python3 scripts/detect_devices.py --json > /tmp/device-map.json

   # Use in automation
   ESP32_PORT=$(jq -r '.[] | select(.device_type=="esp32c6") | .port' /tmp/device-map.json)
   ```

### Benefits
✅ **Scalability:** Works with any number of connected boards
✅ **Repeatability:** Same script works across different setups
✅ **Automation:** No manual intervention needed
✅ **Reliability:** Multiple detection methods ensure accuracy
✅ **Maintainability:** Easy to extend for new board types

## Integration with Existing EAB Infrastructure

### Recommended Changes to eabctl

#### 1. Add `eabctl detect` Command
```python
# In eab/cli/main.py or similar
@cli.command()
@click.option('--json', is_flag=True, help='Output JSON')
@click.option('--device', help='Find specific device type')
def detect(json, device):
    """Detect connected development boards"""
    from eab.cli.device_detect import DeviceDetector

    detector = DeviceDetector()
    devices = detector.scan_all()

    if device:
        found = detector.find_device(device)
        if found:
            if json:
                click.echo(json.dumps(found))
            else:
                click.echo(f"{found['port']}")
        else:
            click.echo(f"Device {device} not found", err=True)
            sys.exit(1)
    else:
        if json:
            click.echo(json.dumps(devices, indent=2))
        else:
            # Print table
            for device in devices:
                click.echo(f"{device['port']:<40} {device['device_type']:<20}")
```

#### 2. Auto-Detection in Flash Command
```python
# In eab/cli/flash.py
@cli.command()
@click.argument('firmware_path')
@click.option('--chip', help='Target chip (auto-detect if not specified)')
@click.option('--port', help='Serial port (auto-detect if not specified)')
def flash(firmware_path, chip, port):
    """Flash firmware to device"""

    # Auto-detect chip and port if not specified
    if not chip or not port:
        detector = DeviceDetector()
        devices = detector.scan_all()

        if not chip and len(devices) == 1:
            chip = devices[0]['chip']
            port = devices[0]['port']
            click.echo(f"Auto-detected: {chip} on {port}")
        elif not chip:
            click.echo("Multiple devices found. Specify --chip:")
            for d in devices:
                click.echo(f"  {d['chip']:<15} on {d['port']}")
            sys.exit(1)

    # Proceed with flash...
```

#### 3. Test Matrix with Auto-Device-Selection
```python
# In regression testing
@cli.command()
@click.option('--suite', help='Test suite directory')
@click.option('--matrix', is_flag=True, help='Run on all available devices')
def regression(suite, matrix):
    """Run regression tests"""

    if matrix:
        detector = DeviceDetector()
        devices = detector.scan_all()

        for device in devices:
            click.echo(f"Testing on {device['device_type']}...")
            run_tests(suite, device=device)
```
