Looking to get hands-on experience with Embedded Linux? In this virtual course, participants will learn about the different components that comprise an Embedded Linux system and how to customize each.
We will also learn about the Qucik Emulator (QEMU) and how it can be used to test customizations of the different Embedded Linux components. We will also learn how QEMU allows us to emulate hardware so that we can get our embedded software up and running without waiting for hardware.
Each session will consist of a lecture with slides and a lab portion. Participants will have their own Linux environment to conduct the labs.
The following outlines what will be covered in each session:
- Day 1
- Embedded Linux system architecture and components
- Introduction to QEMU
- The Embedded Linux boot process
- U-Boot software architecture
- Environment variables in U-Boot
- U-Boot commands
- Lab: Customizing U-Boot in QEMU
- Day 2
- The different types of kernels
- The Linux Kernel: Overview, architecture, and components
- Different Linux Kernel subsystems
- KConfig: Enabling Linux Kernel features
- How the Linux Kernel uses the Devicetree to learn about hardware
- Devicetree Overlays
- Linux Kernel modules
- Emulating hardware to QEMU
- Lab: Implementing an Out-Of-Tree Module to Interact with Hardware and Testing On QEMU
- Day 3
- Kernel-space vs user-space
- Cross-compiling applications to run on embedded systems
- Creating a root filesystem for use in QEMU
- Systemd: Launcing applications on startup
- GDB: How to debug Embedded Linux applications
- Lab: Creating an Application To Interact With Our Hardware
