Key partitions explained:
The file also includes flags like is_ext: true, is_download: true, and partition types (RAWIMG, EXT4, etc.). Key partitions explained:
What if you have the device in hand but lost the scatter file? You can regenerate it using one of two methods:
| Field | Meaning |
|------------------------|-------------------------------------------------------------------------|
| partition_index | Sequential index (SYS0 … SYSn). |
| partition_name | Mount point or logical name (e.g., system, userdata). |
| file_name | Image file to flash (or NONE if not flashed). |
| is_download | If true, the tool flashes a file to this partition. |
| type | Content type – NORMAL (raw), EXT4_IMG, SV5_BL_BIN (bootloader). |
| linear_start_addr | Absolute byte offset in eMMC user area (for EMMC_USER regions). |
| partition_size | Size in bytes (hex). |
| region | EMMC_BOOT_1 (bootloader partition), EMMC_USER (main user area). |
