Linux Device Drivers - Course Overview

The Device Drivers play an important role when a custom hardware is brought up with Linux as an Embedded OS. In this course you will be ramping up yourself in the Linux device drivers from the scratch. 

 

 

The Embedded Systems domain is growing with more diversified set of hardware. When a new board is brought up for a particular functionality, device drivers play an important role by enabling communication via a particular interface.

 

Our Linux Device Driver course starts with an introduction to the drivers ecosystem. It further deep dives into topics like creating character drivers, block drivers, USB drivers and PCI drivers. This workshop also covers various Kernel debugging techniques with KDB / KGDB based on real-practical use cases.

 

Hands-on approach, Expert mentors, Workshop based delivery followed by structured intervention for project work makes this as a unique course for UpSkilling.

best online course for front end development

The Linux device drivers (intermediate) course is to provide developers a kick-start with device drivers. It covers essential parts of driver development, but it doesn’t talk about advanced aspects like network drivers, platform drivers, file-systems drivers etc. In the advanced course it covers such topics to provide you with a complete device driver development exposure. By taking up advanced course you will get comprehensive knowledge about device drivers. Such approach makes us the best institute in India to learn advanced Linux device drivers course.

driver development happens inside the Kernel, doing effective debugging plays a crucial part. Sine we are introducing advanced topics of device drivers in the course, it will remain incomplete if developers are not aware how to troubleshoot / fix issues. Hence a variety of hands-on topics introduced under the debugging techniques (Querying, Printing, Watching, Tracing etc…) which in combination provides power tools & techniques that will help you in real time problem solving.

We understand target audience will have different level of understanding about Linux drivers. It is our best interest to deliver the workshop where the whole class can benefit. If you already have some idea, it will be an added advantage to grasp workshop contents better. During hands-on session we will specifically provide some advanced aspects of drivers (ex: USB) for you to practice and build deeper skills. I already have some idea about device drivers. How does this workshop help me?
