Embedded Linux Development

HRDC Reg. No: 10001657747
Duration: 21 hours (3 days)

Course Overview

This intensive 3-day course provides a comprehensive and hands-on exploration of Linux Block Device and Filesystem Driver Development. Participants will learn how storage systems operate at a low level, from disk structures and partitioning to block I/O handling within the Linux kernel.

The course progresses from implementing a RAM-based block driver to designing and developing a fully functional custom filesystem integrated with the Linux Virtual Filesystem (VFS). By combining theory with real-world implementation, participants gain deep insight into Linux storage architecture and driver development.

Who Should Attend

• Embedded Software Engineers
