Embedded Linux (C, Rust, Python, Bash, Docker, MQTT) overview

An embedded Linux development stack for building custom Linux-based firmware and applications on ARM or RISC-V hardware. C provides low-level driver and kernel module development while Rust handles safety-critical userspace services with memory safety guarantees. Python scripts automate build processes, test harnesses, and hardware provisioning. Bash scripts manage boot sequences and system configuration. Docker containers provide reproducible cross-compilation environments. MQTT enables lightweight device-to-cloud communication for IoT deployments. Targeted at embedded engineers building connected devices, gateways, and industrial controllers. The tradeoff is long build-test cycles and the difficulty of debugging hardware-specific issues in emulated environments.
