Embedded Linux & Edge

Embedded Linux & Edge

Some products sit on a Raspberry Pi or similar SBC: Linux, containers, and a service that talks to an MCU. This subject is putting a small edge stack on a board — a container or systemd service, not a full cloud platform — and being honest about real-time limits of Linux.

Starting Points

• Operating systems & RTOS
• Docker. Get Started.
• Raspberry Pi / Debian documentation for the image you use.

Key Points

• You run a service on Linux that starts on boot and logs enough to debug a failure.
• You package that service in a container or document why a container is the wrong tool for this device.
• You connect the SBC to a microcontroller or sensor and define which side owns which real-time job.
• You keep images and secrets out of git; you version the compose or install notes.
• You explain what Linux will not guarantee (hard real-time) compared with an MCU.
