Introduction to Embedded Linux

Course Aim
To learn how to develop Linux on embedded systems using low-cost, yet powerful Arm-based platforms, including custom peripheral development for various applications with standard industrial software tools.
Why should you take this course
The main advantage of using embedded linux systems is that it is open source and we customise the Linux to our needs and so we can reduce the size of the OS. It already has support for various communication protocols such as http/s, dhcp, ssh, telnet etc. It also supports various platforms like ARM, PowerPC, mips..etc.We can reduce the cost of hardware by taking advantage of multi-tasking operating systems brought to embedded devices. Linux also supports Python, so we can use it to build a more robust system.
