Analyzing the Linker Map file with a little help from the ELF and the DWARF
Running out of Flash or RAM is a familiar pain for firmware engineers, and the linker map only tells part of the story. This post shows how to combine the linker MAP with ELF symbol tables and DWARF debug info to recover static symbols, sizes, and source files that the map omits. It also describes a C# WinForms viewer that automates the parsing with binutils and helps you spot module and symbol-level memory waste.
