Linux handles networking, storage, and the user interface; the MCU handles precise sampling, motor control, or other time-sensitive work. RPMsg (Remote Processor Messaging) provides a message channel between the two processors on supported systems. This guide shows three useful communication patterns: Linux sends commands to the MCU without expecting a reply.
