Mt6577 Android Scatter Emmc.txt <Top · Hacks>
A scatter file describes how firmware is mapped to the eMMC storage — partition names, physical addresses, regions, and file assignments. Unlike older MTK devices using raw NAND, the MT6577 often uses eMMC, which behaves more like an SD card with built-in controller.
⚠️ Incorrect scatter loading can hard-brick the device. Always verify partition sizes/addresses match your exact device variant.
Here’s a breakdown of a single partition entry from an MT6577 scatter:
- partition_index: SYS0
partition_name: PRELOADER
file_name: preloader_mt6577.bin
is_download: true
type: SV5_BL_BIN
linear_start_addr: 0x0
physical_start_addr: 0x0
partition_size: 0x40000
region: EMMC_BOOT_1
[FLASH INFO]
; Please define the size and count of your eMMC
; Block size: 512 byte
; Total size: as your eMMC size (MB)
block_size = 512
total_blocks = 305833984
; Define the regions
[Regions]
region_count = 3
region_0_name = preloader
region_0_start = 0
region_0_size = 524288
region_1_name = loader
region_1_start = 524288
region_1_size = 2097152
; Add more regions as necessary
[PARTITION INFO]
; Define the partition table
partition_count = 12
; Example partition

The scatter file dictates the low-level boot order specific to the MT6577 architecture. You will typically see a hierarchy of partitions essential for the SoC to initialize:
DSP / NVRAM:
MBR (Master Boot Record) / EBR (Extended Boot Record):

| Attribute | Details |
|-----------|---------|
| File Name | MT6577_Android_scatter_emmc.txt |
| Target Chipset | MediaTek MT6577 (Cortex-A9 dual-core, 40nm) |
| Storage Type | eMMC (Embedded MultiMediaCard) |
| Primary Use | Firmware flashing (SP Flash Tool), partition mapping for Android 4.0–4.2 (Ice Cream Sandwich / Jelly Bean) |
| Key Feature | Uses logical block addressing (LBA) based on eMMC user area, not raw NAND addresses. |
The MT6577 was one of MediaTek’s first widely used dual-core smartphone SoCs. The transition from NAND to eMMC in this generation marked a major change in scatter file structure. MT6577 Android scatter emmc.txt
