This course provides an overview of System Programming for the Linux operating system, or software which is interfacing directly with the Linux Kernel and C library. The basic components of a Linux Embedded System, including kernel and root filesystem details are discussed. The Buildroot build system is introduced, which students use to build their own custom Embedded Linux system through programming assignments. Linux System Programming and Introduction to Buildroot can also be taken for academic credit as ECEA 5305, part of CU Boulder’s Master of Science in Electrical Engineering.
