ARM Reverse Engineering Notes

This repository contains some personal notes on reverse engineering and binary analysis for ARM-based embedded systems (mainly Cortex M).

WARNING: This repository is a work in progress. Any information found here may or may not be reliably vetted. Any suggestions or improvements are welcome, but the official ARM documentation should be your go to source of information.
