Embedded Linux Development

HRDC Reg. No: 10001706775
Duration: 28 hours (4 days)

Course Overview

Linux Kernel Programming: Driver Development in Practice is a project-driven, hands-on course that teaches engineers how to design, develop, and debug Linux device drivers for real hardware.

Participants will progressively build a complete event-driven driver while learning kernel modules, character drivers, user-kernel communication, synchronization, wait queues, interrupt handling, deferred work mechanisms, and GPIO-based hardware interaction.

The course emphasizes practical implementation, debugging, and production-quality driver design, enabling engineers to confidently develop and maintain Linux kernel drivers in Embedded Linux environments.

Learning Outcomes

By the end of this course, participants will be able to:

Kernel & Driver Fundamentals

• Explain how device drivers operate within the Linux kernel
• Differentiate between user space and kernel space interactions
• Build and manage Linux kernel modules confidently

Character Driver Development

• Design and implement complete character drivers from scratch
• Create and manage device files for user-space interaction
• Implement file operations such as open, read, write, and ioctl

User–Kernel Communication

• Safely transfer data between user space and kernel space
• Design driver interfaces for both data exchange and control
• Build user-space applications to interact with drivers

Interrupt Handling & Deferred Work

• Implement interrupt-driven drivers for hardware events
