# ONT-S207CW-62TS-SE / Binardat 2G06-04210GSM / Binardat 2G06-04210GS

## Overview

ONT-S207CW-62TS-SE, Binardat 2G06-04210GSM (managed), and Binardat 2G06-04210GS (unmanaged) are **switches with identical hardware**:
- **CPU:** RTL8372N (confirmed via serial: "Detecting CPU: RTL8372N")
- **Flash:** GD25Q128E (16MB)
- **Ports:** 4x 2.5G RJ45 + 2x 10G SFP+
- **Console:** 115200 baud (RTLPlayground firmware) / 9600 baud (stock firmware)

**Note:** These devices use **PCB-SWTG024AS-A-2.0.1** hardware. The `MACHINE_ONT_S207CW_62TS_SE` definition uses a **custom configuration** with:
- Corrected port mapping (physical ports 1-4 = RJ45, 5-6 = SFP)
- Optimized LED sets for different port wiring (RJ45 Ports 1-2 have reversed LED wiring)
- Custom LED mux configuration from PCB-SWTG024AS-A-2.0.1

## Port to Logical Mapping

Custom mapping for ONT-S207CW-62TS-SE:

| Physical Port | Logical Port | Type | LED Set |
|---|---|---|---|
| 1 | 7 | RJ45 | 2 |
| 2 | 6 | RJ45 | 2 |
| 3 | 5 | RJ45 | 0 |
| 4 | 4 | RJ45 | 0 |
| 5 | 3 | SFP+ (SDS0) | 3 |
| 6 | 8 | SFP+ (SDS1) | 3 |

**Note:** Ports 1-2 (RJ45) have reversed LED wiring and use LED-Set 2. SFP Ports 5-6 use LED-Set 3 to account for wiring differences.

## Firmware Files

| File | Size | Purpose |
|---|---|---|
| `ONT_S207CW_62TS_SE-v22.bin` | 524288 bytes | Direct flash via CH341A/SPI programmer |
| `rtlplayground_oem_upgrade-ONT_S207CW_62TS_SE-v22.bin` | 540710 bytes | OEM upgrade via web UI (Loader Mode) |

### Firmware Size Check
- **Flash chip:** GD25Q128E = 16MB = 16777216 bytes
- **Firmware size:** 524288 bytes (512KB)
- **Status:** ✅ **Plenty of space available** - No size issues with old or new web UI

## Flashing Instructions

### Prerequisites
- **GD25Q128E** flash chip (16MB)
- **CH341A** SPI programmer (recommended)
- **flashrom** tool (Linux) or **Flashrom GUI** (Windows)

### Via CH341A (Direct Flash)

**Linux (flashrom):**
```bash
# Install flashrom first
sudo apt install flashrom

# Flash the firmware (may need sudo)
flashrom -p ch341a_spi -c "GD25Q128E/GD25B128E/GD25R128E/GD25Q127C" -w ONT_S207CW_62TS_SE-v22.bin --noverify-all
```

**Alternative command (if above fails):**
```bash
flashrom -p ch341a_spi -c "GD25Q128E" -w ONT_S207CW_62TS_SE-v22.bin
```

### Via Loader Mode (Web UI Upgrade)

The OEM upgrade file can be flashed via the device's loader mode:

1. **Enter Loader Mode:**
   - Power off the switch
   - Hold the reset button
   - Power on while holding reset
   - Release after ~5 seconds
   - Switch should be accessible at `192.168.10.247`

2. **Upload via HTTP:**
   ```bash
   curl -T rtlplayground_oem_upgrade-ONT_S207CW_62TS_SE-v22.bin http://192.168.10.247/firmware
   ```

3. **Or via Web Browser:**
   - Access `http://192.168.10.247`
   - Use the firmware update function
   - Upload `rtlplayground_oem_upgrade-ONT_S207CW_62TS_SE-v22.bin`
   - Wait for completion and reboot

### Via RTLPlayground Web UI (After First Flash)

Once RTLPlayground firmware is running:
1. Access web interface at `http://192.168.2.1`
2. Navigate to **System > Firmware Update**
3. Upload the `.bin` file
4. Wait for flash completion and reboot

## Recovery

If flashing fails and the switch does not boot:

### Method 1: Loader Mode Recovery
- The loader mode always remains accessible
- Switch boots to `192.168.10.247` when in loader mode
- Flash via: `curl -T firmware.bin http://192.168.10.247/firmware`

### Method 2: Serial Recovery (if loader mode fails)
- Connect UART: 115200 baud, 8N1
- Use CH341A to flash directly:
  ```bash
  flashrom -p ch341a_spi -c "GD25Q128E" -w firmware.bin
  ```

### Method 3: SOIC8 Clip
- Connect SOIC8 clip to CH341A
- Use flashrom as above
- Chip: GD25Q128E (16MB)

## Stock Firmware Information

| Property | Value |
|---|---|
| **Default IP** | 192.168.2.1 (ONT) / 192.168.10.247 (Loader Mode) |
| **Default Login** | admin/admin (may vary by OEM) |
| **Console Baud** | 9600 (stock) / 115200 (RTLPlayground) |
| **CPU String** | "RTL8372N" |
| **Loader Mode IP** | 192.168.10.247 |

## Configuration Details

- **CPU:** RTL8372N (`.isRTL8373 = 0`)
- **SFP:** SDS0 on logical port 3 (GPIO37), SDS1 on logical port 8 (GPIO38)
- **Port Mapping:** Physical 1-4 → Logical 7-4, Physical 5-6 → Logical 3,8
- **LED Wiring:** RJ45 Ports 1-2 and SFP Port 6 have reversed LED pins (orange/green swapped)
- **LED Sets:** 4 sets total - Set 0/1 unused, Set 2 for RJ45 1-2, Set 3 for SFP 5-6

## Notes

- ONT-S207CW-62TS-SE, Binardat 2G06-04210GSM (managed), and Binardat 2G06-04210GS (unmanaged) use **identical PCB-SWTG024AS-A-2.0.1 hardware**
- Web UI shows correct physical port order (1-2-3-4 for RJ45, 5-6 for SFP)
- Loader Mode always remains accessible at `192.168.10.247` for recovery
- Serial console: 9600 baud (stock) → 115200 baud (RTLPlayground)
