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):

# 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):

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:

    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: 
    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)

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)
