Mt6761 Scatter File Top -

Rating: 4.5/5 (Essential Utility)

The MT6761 scatter file is a robust, text-based definition that is indispensable for MediaTek device maintenance. While the file itself is static, its quality is determined by the accuracy of the hex addresses.

Conclusion: If you are looking at the "top" of an MT6761 scatter file, you are looking at the skeleton of the device's operating

MT6761 devices running Android 10+ use a super partition (logical volume for system, product, vendor). The "top" of the scatter file must reflect the correct size.

Incorrect top entry: partition_size: 0x2000000 (32MB) – Too small. mt6761 scatter file top

Correct top entry for a 4GB userdata device: partition_size: 0x80000000 (2GB for super)

How to edit: Locate the super entry in the top half of the file (just before metadata or userdata). Adjust partition_size in hex, ensuring it aligns with block_size: 0x20000.

Because scatter files are also used by low-level memory tools where boundaries must be explicit. The top value ensures no overlap and helps with integrity checks.

A complete scatter file is divided into two major logical sections: Rating: 4

This report focuses exclusively on the Top Section.

The MT6761 (Helio A22) uses a typical address layout:

| Partition | Start Addr | Size | Top | |-----------|------------|------|------| | preloader | 0x0 | 0x40000 | 0x40000 | | pgpt | 0x0 (EMMC_USER) | 0x2000 | 0x2000 | | proinfo | 0x80000 | 0x300000 | 0x380000 | | nvram | 0x380000 | 0x500000 | 0x880000 | | boot | 0x900000 | 0x2000000 | 0x2900000 | | system | 0x2900000 | 0x80000000 | 0x82900000 |

⚠️ These are examples — always check your own scatter file from the original firmware. Conclusion: If you are looking at the "top"

The line # - TOP ---------------------------------------------------------------------- is a visual marker, but the actual TOP region is defined a few lines later as a dedicated partition. Let’s examine that.
