Embedded Linux Development (LFD450)

4.5/5

This instructor-led course will give you the step-by-step framework for developing an embedded Linux product. Starting with the cross-compiler, you’ll learn about setting up a development system, boot loaders, the kernel, drivers, device tree, and all the various software and decisions that need to be made when building a user space root filesystem, such as those in use in consumer electronics, military, medical, industrial, and auto industries. Hands-on labs with a RISC-V based emulated development target allow students to practice both coding and building the various parts of the system covered in class.
