# Bare-metal C programming on ARM This repository contains a tutorial ebook concerning programming a bare-metal ARM system. More specifically it deals with a ARMv7A version of the ARM Versatile Express platform, emulated on a regular PC through QEMU. You can explore the repository, or read things in order. ## Table of Contents An up-to-date PDF version is [also available](http://umanovskis.se/files/arm-baremetal-ebook.pdf). The following chapters can be thought of as the first edition of the ebook, providing a complete path from getting started to a working program that uses hardware features. * [Chapter 0](doc/00_introduction.md): Introduction. A brief intro to the subject and the ebook. * [Chapter 1](doc/01_setup.md): Setup. A short chapter dealing with preparing a Linux environment for further development. * [Chapter 2](doc/02_first_boot.md): The first boot. Basic use of QEMU and the cross-compiler toolchain, getting the simplest possible code to run. * [Chapter 3](doc/03_bootloader.md): Adding a bootloader. Building the highly popular U-Boot bootloader, and getting it to boot our own code. * [Chapter 4](doc/04_cenv.md): Preparing a C environment. This chapter deals with the necessary work for getting from startup in assembly code to C code. * [Chapter 5](doc/05_cmake.md): Build & debug system. Here we show how the work can be streamlined by adding a CMake-based build system, and how the bare-metal program can be debugged. * [Chapter 6](doc/06_uart.md): UART driver development. In this chapter, a device driver for a UART gets written. * [Chapter 7](doc/07_interrupts.md): Interrupts. The chapter goes through setting up the ARM Generic Interrupt Controller, using it to receive and respond to interrupts. Also the UART driver gets adapted to use interrupts. * [Chapter 8 - WIP](doc/08_scheduling.md): Scheduling. Work in progress. ## Repository structure The repository consists of two top-level folders. The `doc` folder contains the actual tutorial chapters. The `src` folder contains the source code corresponding to each chapter. So, for instance, [src/04_cenv](src/04_cenv) contains the source code as it looks after completing Chapter 4. Additionally, the `src` folder has some shared things. `src/common_uboot` holds a stripped-down version of U-Boot used in the examples. Have fun, and feel free to tweak and experiment, that being a great way to learn!
