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

## Overview

ONT-S207CW-62TS-SE and Binardat 2G06-04210GSM are **managed 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** but with different port mapping and LED configuration than the stock PCB-SWTG024AS-A-2.0.1 firmware. Therefore, they require their own machine definition (`MACHINE_ONT_S207CW_62TS_SE`).

## Port to Logical Mapping

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

**Important:** The web UI will show ports in the correct physical order (1-4 RJ45, 5-6 SFP) because the logical-to-physical mapping preserves the order.

## Firmware Files

| File | Size | Purpose |
|---|---|---|
| `rtlplayground-ONT_S207CW_62TS_SE-v11.bin` | 524288 bytes | Direct flash via CH341A/SPI programmer |
| `rtlplayground_oem_upgrade-ONT_S207CW_62TS_SE-v11.bin` | 540710 bytes | OEM upgrade via web UI (Loader Mode) |

### Firmware Size Check
- **Flash chip:** GD25Q128E = 16MB = 16777216 bytes
- **Firmware size:** ~512KB-528KB
- **Status:** ✅ **Plenty of space available** - No size issues with either 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 rtlplayground-ONT_S207CW_62TS_SE-v11.bin --noverify-all
```

**Alternative command (if above fails):**
```bash
flashrom -p ch341a_spi -c "GD25Q128E" -w rtlplayground-ONT_S207CW_62TS_SE-v11.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-v11.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-v11.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 |

## Known Issues & Fixes

### ✅ Issue: LEDs showing wrong colors (FIXED in v11)
**Symptom:** All RJ45 ports show green at all speeds, SFP LEDs incorrect
**Root Cause:** Wrong LED mux configuration and LED set assignments
**Fix:** Use v11 firmware with:
- Original firmware LED mux values (extracted from stock firmware)
- Correct LED set to physical port mapping
- Proper LED color logic (Green=2.5G/10G, Orange=1G/2.5G/100M/10M)

### ✅ Issue: Port order reversed in web UI (FIXED in v11)
**Symptom:** Web UI shows ports as 4321 instead of 1234
**Root Cause:** Incorrect log_to_phys_port and phys_to_log_port mapping
**Fix:** Corrected mapping to preserve physical port order

### ✅ Issue: No network connectivity after flash (FIXED)
**Symptom:** Switch boots but no ping response
**Root Cause:** Wrong CPU type configuration
**Fix:** Ensure `.isRTL8373 = 0` (this is RTL8372N, not RTL8373)

### ✅ Issue: SFP modules not detected (FIXED)
**Symptom:** SFP ports not working
**Root Cause:** Wrong SFP port SDS assignments
**Fix:** Correct SDS0/SDS1 assignments and GPIO pins

## Version History

| Version | Date | Changes | Status |
|---|---|---|---|
| v3 | 2026-09-14 | Initial PCB_SWTG024AS_A_2_0_1 config | ❌ Port order wrong, LEDs wrong |
| v10 | 2026-09-17 | LED colors corrected | ⚠️ LEDs better, port order still wrong |
| v11 | 2026-09-18 | **Separate machine def, correct port mapping, original LED mux** | ✅ All working |

## Notes

- This device shares PCB-SWTG024AS-A-2.0.1 hardware but requires **different port mapping and LED configuration** than the stock PCB-SWTG024AS-A-2.0.1 definition
- **Binardat 2G06-04210GSM is 100% hardware compatible** with ONT-S207CW-62TS-SE
- Port numbering in web UI now matches physical port order (1-4 RJ45, 5-6 SFP)
- LED colors now match the labels on the device enclosure:
  - Green = 2.5G (RJ45) / 10G (SFP)
  - Orange = 1G/100M/10M (RJ45) / 1G/2.5G (SFP)
- The **Loader Mode** always remains accessible at 192.168.10.247 for recovery
- Serial console baud rate changes from 9600 (stock) to 115200 (RTLPlayground)
