Example snippet:

Introduction In the world of embedded systems, the gap between compiled firmware and a bootable device is bridged by a crucial piece of utility software: the flash programming tool. Among these, Flash Image Tool V12 (often abbreviated as FIT V12) has emerged as a reference-grade solution for creating, validating, and deploying flash images across NAND, NOR, and eMMC memory technologies. Unlike generic hex dumpers or simple programmers, FIT V12 is a layout compiler —it understands partition tables, erase blocks, ECC (Error Correcting Code) schemes, and boot metadata.
