+
+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.

+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 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.
