mt6580-android-scatter.txt — Readable feature overview

Below is a clear, structured description of a typical MT6580 Android scatter file (mt6580-android-scatter.txt), showing its purpose, format, common partition entries, fields, and practical notes for developers and modders.

Purpose

• A scatter file maps the memory layout of MediaTek (MTK) devices to enable flashing tools (e.g., SP Flash Tool) to write specific images to specific partitions in eMMC/flash.
• It lists partition names, physical offsets, sizes, file paths for images, and memory regions for the bootloader and Android partitions.

2. File Structure & Syntax

The scatter file is key‑value based with block descriptors. Example snippet: mt6580-android-scatter.txt

PRELOADER 0x0
__attribute__((__page_size__(0x200)))  /* 512 bytes */
__attribute__((__page_size__(0x800)))  /* 2 KB */

  partition_name: PRELOADER
  file_name: preloader_mt6580.bin

  type: SV5_BL_BIN
  linear_start_addr: 0x0
  physical_start_addr: 0x0
  partition_size: 0x40000

What Exactly is a Scatter File?

A scatter file (extension .txt) is a plain-text configuration file that describes the partition layout of the eMMC (embedded MultiMediaCard) or NAND flash storage on an Android device. Think of it as a map or a blueprint. For the MT6580, this file tells the flashing tool exactly where to write each component of the firmware: which sector contains the bootloader, where the kernel lives, and how large the user data partition should be. mt6580-android-scatter

The naming convention—mt6580-android-scatter.txt—is not arbitrary. It explicitly ties the file to: A scatter file maps the memory layout of

• Processor: MediaTek MT6580 (ARMv7, 32-bit, no LTE modem).
• OS: Android (though technically it works for any OS using MTK tools).
• Type: Scatter format, typically version 1.0 or 1.1.
