A valid MT6577 eMMC scatter must satisfy:
: It enables the flashing tool to identify which local files (e.g., system.img , recovery.img ) correspond to which hardware partitions. Key Components of the Scatter File
| Field | eMMC version | NAND version | |-------|--------------|--------------| | Addressing | Linear hex offsets (byte-accurate) | Page/block based | | partition_index | Usually omitted | Present | | linear_start_addr | Explicit start block | Not used | | physical_start_addr | Same as linear for eMMC | NAND chip layout | MT6577 Android scatter emmc.txt
: SP Flash Tool cannot initialize DRAM. Often due to mismatched Preloader or corrupted timing parameters. Fix : Flash only the Preloader first (uncheck all other partitions). If preloader fails, your only recourse is a hardware flasher.
