Firmware analysis means navigating thousands of binaries, kernel modules, and shared libraries whose interactions are rarely documented. Without dedicated tooling, understanding the system before auditing it costs hours. Pyrrha is an open-source firmware cartography ecosystem that automates this orientation work at three levels of detail: a dependency graph of inter-binary relationships (who imports what from whom), a firmware-wide call graph connecting every function call across all binaries, and decompiled source code annotated with those cross-binary call edges. All results land in queryable graph databases that can be explored and searched visually.
