| Partition | Typical Start | Purpose | |-----------|--------------|---------| | | 0x0 | First-stage bootloader; initializes DRAM, loads UBOOT . | | PMT | 0x400000 | Partition Management Table – internal map for MTK’s partitioning scheme. | | UBOOT | 0x600000 | Second-stage bootloader (LK – little kernel). Handles fastboot, boot selection. | | BOOTIMG | 0xa00000 | Kernel + ramdisk (boot partition). | | RECOVERY | 0x1200000 | Recovery image (TWRP/stock recovery). | | SEC_RO | 0x1a00000 | Secondary read‑only region (often signature or custom data). | | LOGO | 0x2200000 | Boot logo (usually a raw RGB565 or BMP). | | EBR1 | 0x2a00000 | Extended Boot Record #1 – logical partition table for ANDROID , CACHE , etc. | | ANDROID | 0x2a40000 | System partition ( /system ) – Android framework/apps. | | CACHE | 0xca40000 | Cache partition (OTA downloads, temporary data). | | USRDATA | 0x17240000 | User data ( /data ) – apps, settings, internal storage. | | EBR2 | 0xffffffffffffffff | Second EBR – often unused, marked with sentinel value. |
