Mapview

MapView is a powerful linker map file analyzer and visualizer designed for embedded systems developers, firmware engineers, and anyone working with compiled binaries who needs to understand memory usage and optimize their code size. Now with experimental support for parsing ELF files.

MapView also includes a command-line interface (CLI) tool for automated analysis and CSV export. To start the CLI version call mapview_cli from powershell or cmd.
