Embedded Linux Roadmap

Start here: what embedded Linux is and why, a quick start, the boot sequence on Raspberry Pi and BeagleBone, and toolchains.

From hello world to input and output, conditions, loops, arguments, strings and functions, with labs.

How a C++ compiler works inside: lexer, parser, semantic analysis, IR, optimizer and code generation.

Basics, functions, loops and conditions, built-in rules, building a library, embedded targets (STM32/ARM) and code coverage.

Basics, include directories, variables, libraries, configure_file, functions, find_package and install, plus an ATmega32 project.

Moving from C to C++: bool, ranged for loops, functions, initialization, references, auto, const, structs and enums.

Object-oriented C++: classes, constructors and destructors, friend, default/delete, const, static and operator overloading.

Singleton, Factory, Builder and Adapter, applied to embedded systems.

Breakpoints, watch and display, segmentation faults, stack smashing, reverse debugging, remote debugging on Raspberry Pi, Python and ARM.

Unit testing C++ with CMake and GoogleTest: TEST, EXPECT and ASSERT, fixtures, matchers, fakes, stubs and mocks.

Install GoogleTest, then write TEST() cases, assertions and TEST_F fixtures.

Emulate a Raspberry Pi with QEMU: U-Boot, SD card, kernel, initramfs, BusyBox, init process and login shell, with no hardware needed.

Kernel modules on Raspberry Pi: hello world, module parameters, major numbers, device files, read and write, error handling, and calling a driver from C, C++ and Python.

A project from the diploma: U-Boot over TFTP, NFS root filesystem, hardware bring-up and the application, on Raspberry Pi or QEMU.

Inter-process communication for automotive: what SOME/IP is, CommonAPI, tools, FIDL and code generation, client to service.

An embedded Linux project with an I2C device driver.

A smart home workshop: announcement and workspace setup.

A circular buffer developed live: unit tests, code coverage, initializer_list and custom iterators.
