+
+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.

+
+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.

+Hex values are in bytes.

+Name            | Start    | Length             | End
+----------------|----------|--------------------|---------
+Bootloader      | 0x000000 | 68 KiB / 0x11000   | 0x011000
+App Image       | 0x011000 | 1.1 MiB / 0x121000 | 0x132000
+OTA Image       | 0x132000 | 664 KiB / 0xA6000  | 0x1D8000

+User Data       | 0x1E3000 | 116 KiB / 0x1D000  | 0x200000
+
+Bootloader and app partitions contain CRC16 sums every 32 bytes. That results in the actual flash offsets/sizes not aligned to sector boundaries. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were aligned to 4096 bytes.

+
+Hex values are in bytes.

+Name            | Start    | Length             | End
+----------------|----------|--------------------|---------
+Bootloader      | 0x000000 | 68 KiB / 0x11000   | 0x011000
+App Image       | 0x011000 | 1.1 MiB / 0x121000 | 0x132000
+OTA Image       | 0x132000 | 664 KiB / 0xA6000  | 0x1D8000

+User Data       | 0x1E3000 | 116 KiB / 0x1D000  | 0x200000
+
+Bootloader and app partitions contain CRC16 sums every 32 bytes. That results in the actual flash offsets/sizes not aligned to sector boundaries. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were aligned to 4096 bytes.

+RDP             | 0x1FF000 | 4 KiB / 0x1000    | 0x200000
+
+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.

+RDP             | 0x1FF000 | 4 KiB / 0x1000    | 0x200000
+
+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.
