Firmware History

Version	Date	Changes	Status
v3	2026-09-14	Original PCB_SWTG024AS_A_2_0_1 config	✅ All ports working, LEDs wrong
v10	2026-09-17	LED colors corrected for RJ45 and SFP+	✅ All ports + LEDs working

Firmware Files

File	Purpose
rtlplayground-ONT_S207CW-v10.bin	Direct flash via CH341A
rtlplayground_oem_upgrade-ONT_S207CW-v10.bin	OEM upgrade via web UI

Flashing Instructions

Via Loader Mode (CH341A)

flashrom -p ch341a_spi -c "GD25Q128E" -w rtlplayground-ONT_S207CW-v10.bin

Via Web UI

1. Access the web interface at http://192.168.2.1
2. Navigate to Firmware Update (under System tab)
3. Upload rtlplayground_oem_upgrade-ONT_S207CW-v10.bin
4. Wait for flash completion and automatic reboot

Recovery

If flashing fails and the switch does not boot:

1. Loader Mode Recovery:

   • Hold reset button while powering on
   • Switch should be accessible at 192.168.10.247
   • Flash via curl -T firmware.bin http://192.168.10.247/firmware

2. Serial Recovery:

   • Connect via UART (115200 baud for RTLPlayground, 9600 for stock)
   • Use CH341A: flashrom -p ch341a_spi -c "GD25Q128E" -w firmware.bin

Stock Firmware Information

• Default IP: 192.168.10.247
• Default Login: admin/admin (varies by OEM)
• Console Baud: 9600
• CPU: RTL8372N

Known Issues & Fixes

Issue: LEDs showing wrong colors

Symptom: RJ45 ports show green at all speeds, SFP LEDs don't light up Fix: Use v10 firmware with corrected LED sets and LED mux configuration

Issue: No network connectivity after flash

Symptom: Switch boots but no ping response Fix: Ensure .isRTL8373 = 0 (RTL8372N) is set - this device uses RTL8372N, not RTL8373

Notes

• This device shares the exact same PCB as PCB-SWTG024AS-A-2.0.1
• The hardware detection string is "PCB-SWTG024AS-A-2.0.1"
• Port numbering in the web UI may appear reversed (4321 instead of 1234) due to the port mapping, but physical ports 1-4 are RJ45 and 5-6 are SFP+
