Request for rtl8723ds_fw.bin for RS308D4P1W10 (Rock Pi S)

Hello,

I am developing a WiFi application on my RS308D4P1W10 evaluation board (Radxa Rock Pi S, RK3308 with the RTL8723DS WiFi chip). I need the Linux firmware file rtl8723ds_fw.bin, but I cannot find it in any official images or repositories. Could someone please help me obtain this file, or let me know where I can legally download it?

I have already tried extracting it from the official images, but it is not provided there.

Thank you very much for your support!

Best regards,

Ham
