Embedded Linux and
Real-Time Linux Training
Embedded and
Real-Time
Linux Development
This four and a half day course (sometimes offered in four
days format) provides the knowledge and skills to develop an embedded
Linux product. The course shows attendees how to configure a small
Linux kernel, develop code within the kernel for support of their
target platform and application, and how to measure and obtain
real-time performance with Linux.
The course begins with a complete, simple, project that walks the
attendees through the entire process of creating a special version of
the Linux kernel, creating a root file system, including just the
libraries that are needed, and constructing a custom boot sequence.
The course covers the key issues in embedding Linux. Such questions as:
why Linux, how to embed Linux, and how to measure and obtain real-time
performance in Linux are examined. The attendees will gain experience
in developing applications and system programs. These examples include
hard and soft real-time applications. The issues with real-time in
Linux will be examined in detail.
Attendees will spend approximately 50 percent of the class time
actually gaining hands-on experience with these topics, with personal
attention and insider knowledge from an experienced embedded Linux
developer.
The following
modules
will be covered during the class:

Class
Duration: Four
and a half days
Prerequisites:
The
course is designed for real-time or embedded engineers who are new to
real-time or embedded Linux. Attendees should have experience with the
C programming language, processor architectures, memory management and
basic Unix knowledge.
If you have any
questions
about the difficulty level of the class, please contact us at classes@linuxcertified.com.
Course Materials: The workshop materials
include a comprehensive student workbook and CD. The workbook contains
all of the slides used in the course as well as hands-on lab exercises.
The CD contains the lab
exercise code as well as a large amount of embedded and real-time Linux
software.
Optional:
All
attendees will get a Linux laptop to be used during the class. You have
the option of purchasing this laptop with an additional course fee.
