A step-by-step guide to building QEMU from source inside a Docker container and debugging it with VS Code. The setup targets ARM and AVR emulation for embedded development, motivated by a university research project implementing a software simulator for the NXP EZH/SmartDMA co-processor. The guide covers a complete Dockerfile that installs prerequisites, clones and builds QEMU and GDB from source, compiles a semihosting test application, and configures VS Code launch settings for GDB-based debugging inside the container.
