physical_start_addr : The actual physical location on the storage chip.
Before diving into scatter files, it is worth understanding the hardware at the heart of this topic. The MediaTek MT6833, commonly marketed as the Dimensity 700 5G, is a mid-range octa-core application processor released in late 2020. Built on TSMC’s 7nm semiconductor process, the chipset integrates two ARM Cortex-A76 performance cores clocked up to 2.2 GHz alongside six ARM Cortex-A55 efficiency cores capped at 2.0 GHz. This heterogeneous architecture supports ARMv8.2-A instruction set and operates with LPDDR4X memory interfaced via a dual-channel 16-bit bus.

When an updated scatter file is loaded into the SP Flash Tool, the tool attempts to write the new partition layout starting at Logical Block Address (LBA) 0. However, the BROM on the MT6833 will compare the written partition metadata against its hardware-defined memory map. If the scatter file attempts to move a protected partition (e.g., seccfg , persist ) or resize boot without corresponding adjustments to the Preloader’s internal address references, the device will reject the update and enter BROM error mode (often indicated by a red bar in SP Flash Tool and a disconnected USB device).
Before performing any firmware flashing operation with a scatter file, ensure you have these items ready: physical_start_addr : The actual physical location on the
