Mt6761 Scatter File May 2026

The MT6761 scatter file is well-structured for a modern ARM SoC. It correctly implements MTK_DYNAMIC_PARTITION_SUPPORT (Super partition) for system/vendor/product, while keeping low-level partitions (preloader, boot, sec1) physically mapped. Rating: 8/10 – Robust for its class, but requires caution with linear2addr and partition_id ordering. Key Sections Analyzed 1. General Configuration - general: MTK_DYNAMIC_PARTITION_SUPPORT = yes - general: HEAP_SIZE = 0x0 - general: PAGE_SIZE = 0x200 ✅ Good – Dynamic partition support reduces hard-coded system partition boundaries. ⚠️ HEAP_SIZE: 0x0 means default heap; fine for most use, but custom bootloaders may need explicit value. 2. Preloader & Bootloaders - name: preloader_a linear_start_addr: 0x0 physical_start_addr: 0x0 partition_size: 0x40000 region: EMMC_BOOT_1 ✅ Correct placement in EMMC_BOOT regions – critical for boot chain. ✅ preloader_a size 256KB is adequate for MT6761. 3. Security Partitions - name: sec1 linear_start_addr: 0x0 partition_size: 0x200000 region: EMMC_USER ⚠️ Potential issue – linear_start_addr: 0x0 in EMMC_USER overlaps with GPT? Typically sec1 lives at 0x0 only if no GPT. Usually sec1 starts after GPT (e.g., 0x800000). Check if your device uses GPT – if yes, this might brick the partition table on flash. 4. Dynamic Partitions (Super) The scatter defines only super as physical, then inside super:
