Linux Device Drivers - Short Term Course - FAQs

We are pretty sure you will have a lot of questions before joining our courses. Here are the frequently asked questions for your reference. In case you still have anything specific write to us at training@emertxe.com

What is the difference between this and Linux device drivers?

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.

Why debugging techniques are highlighted in this 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.

I already have idea about device drivers. How will this help me?

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?

What projects can I work on after course completion?

There are many projects that you can work on based on the course learning. A sample list of projects are provided below.

USB Mass Storage (MMC) driver
USB to Serial converter
Complex matrix keypad driver using interrupts and synchronization
Ethernet based network drivers
File system drivers
Platform drivers

Such comprehensive list of project based learning makes us the best Institute in India to learn advanced linux device drivers course.

Who are the trainers for Linux device drivers workshop?

Trainers (mentors in Emertxe) for this workshop are professionals having worked with organizations like Samsung, HP, Novell, Huawei etc., that makes Emertxe as one of the best Linux training institutes in Bangalore. They bring in 18+ years of experience on average. Our mentors understand industry requirements very well in order to maximize the value.
