Linux, the free, Open Source operating system, is rapidly emerging as the leading platform for embedded devices using high-performance, 32-bit processors. And as the cost of computing continues to plummet, these processors are showing up just about everywhere. The ARM architecture, featuring a relatively high performance-to-power ratio, has become popular in a wide range of consumer and industrial electronic products including cell phones, set-top boxes and robots to name just a few.

This 3-day seminar focuses on how Linux has been adapted for use in embedded environments, with specific emphasis on the ARM architecture. Through extensive hands-on lab work, you learn how to install a cross-development environment, build a compact version of Linux for an embedded device, install the build on the target system, and test its operation. You’ll create and test programs that exercise I/O as well as networking applications.

Each participant receives a CD with a complete Linux kernel distribution, including source code, and ARM cross-development toolkit, which provides an ideal platform for embedding Linux into a wide range of consumer and industrial devices.

Participants will have available for use during the class an ARM-based target single-board computer (SBC) kit. This is the same SBC supplied with the Embedded Linux Learning Kit and is offered at a substantial discount to class participants.
