RDP is most likely not used in Tuya firmwares, as the System Data partition contains
an incorrect offset 0xFF000 for RDP, which is in the middle of OTA2 image.
RDP is most likely not used in Tuya firmwares, as the System Data partition contains an incorrect offset 0xFF000 for RDP, which is in the middle of OTA2 image.
Additionally, Tuya firmware uses an encrypted KV or file storage, which resides at the end of flash memory. This seems to overlap system RDP area.
