For the MediaTek MT6761 (Helio A22) – a 12nm quad-core processor found in devices like the Xiaomi Redmi 6A, Redmi 7A, and various Alcatel and Realme entry-level phones – the scatter file is non-negotiable. Without it, you cannot:

The MT6761 is a 12nm FinFET quad-core ARM Cortex-A53 processor designed for entry-level smartphones and IoT devices. It lacks the high-performance cores of its MT6762/MT6765 siblings but maintains identical memory mapping architecture for compatibility.

# General GENERAL: PLATFORM = MT6761 BOARD = sp9863a_1c10 (example) CPU = Cortex-A53 NAND_INFO = 0x0, 0x0 EMMC_INFO = 0x0, 0x0

The "top" of an MT6761 scatter file (usually version 1.1 or higher) generally follows the standard MediaTek partition definition format.

: It ensures that subsequent partitions (like PGPT , PROINFO , NVRAM ) start at a clean sector boundary. The 0x40000 start address (256 KB) leaves room for the Primary GPT (if used) and the Preloader’s backup.
