Embedded Linux Development

HRDC Reg. No: 10001706250
Duration: 21 hours (3 days)

Course Overview

Embedded Linux System – Build, Boot & Recover provides engineers with a complete understanding of the Embedded Linux boot process, from power-on through bootloader, kernel, and root filesystem. Participants will learn how to configure and build Linux systems, control boot behavior using U-Boot, debug boot failures, recover bricked devices, and develop a structured approach to troubleshooting Embedded Linux platforms.

The course emphasizes practical recovery, debugging, and system-level understanding required for real-world embedded product development.

You will learn how to:

• Trace the complete boot sequence and identify failure points
• Debug boot issues systematically instead of guessing
• Work confidently with U-Boot and control boot flow
• Build and configure the Linux kernel for your target
• Create and integrate a minimal root filesystem
• Recover a non-booting or bricked board using practical techniques

By the end of the program, participants will move from trial-and-error debugging to structured problem-solving, enabling them to bring up, debug, and recover Embedded Linux systems with confidence.

Learning Outcomes

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

System Understanding

• Explain the complete Embedded Linux boot flow from ROM to root filesystem
• Identify where and why a system fails during boot

Bootloader Control

• Navigate and configure U-Boot environment variables
• Modify boot arguments to control system behavior
• Build and extend bootloader functionality

Kernel Configuration & Building

• Configure and build the Linux kernel for a target platform
• Debug kernel boot issues and interpret boot logs

Root Filesystem Integration

• Create a minimal root filesystem using BusyBox
• Integrate init scripts and boot dependencies
• Boot using different root filesystem strategies such as initramfs and NFS

Board Recovery

• Apply a structured debugging approach to boot failures
• Identify failure stages including bootloader, kernel, and rootfs
• Recover a bricked board using existing images and fallback strategies
