This paper describes the experience of customizing RTLinux for its use in embedded real-time control. The paper describes the system configuration, the issues involved in minimizing Linux for a small-embedded system. The paper introduces the concept of file system profiles to deal with minimization. Another interesting feature is how to achieve real-time features through the use of RT-Linux. Finally, it describes the design of a CAN network driver for providing real-time transmission on a RT-Linux system.
