sel4-tutorials

Various tutorials for using seL4, its libraries, and CAmkES.

Prerequisites

Download the prerequisites for building and running the tutorial code following the instructions.

Building using CMake:

Caveats:

No support for CAmkES currently:

Only the native seL4 tutorials can currently be built with the CMake build system. The CAmkES tutorials are currently unsupported. I.e, the following tutorials cannot be built with the CMake build system:

  • hello-camkes-0
  • hello-camkes-1
  • hello-camkes-2
  • hello-camkes-timer

Don't forget to pass -DAARCH32 or -DAARCH64:

If you're compiling for any ARM platform, please don't forget to pass in the extra -DAARCH32 or -DAARCH64 flag (depending on whether you're compiling for 32-bit or 64-bit ARM) when invoking CMake.

Choosing your target machine and compiling

Invoke the CMake build system to begin trying your changes to the exercises:

# Create a new folder in which to compile your files:
mkdir cbuild
cd cbuild

# Invoke CMake using the shell script wrapper in the root directory:
 ../init-build.sh \
    -DTUTORIAL=<PREFERENCE> \
    -DTUT_BOARD=<PREFERENCE> \
    -DTUT_ARCH=<PREFERENCE> \
    -DBUILD_SOLUTIONS=<BOOLEAN_PREFERENCE>

# Invoke ninja to compile the tutorials
ninja
  • TUTORIAL is used to select the tutorial you'd like to compile.
  • BUILD_SOLUTIONS can be set to true or false to determine whether the exercises or the solutions are selected for compilation.

Use combinations of TUT_BOARD and TUT_ARCH to select the target machine to compile for.

The officially supported combinations of TUT_BOARD and TUT_ARCH are:

  • TUT_BOARD=pc, TUT_ARCH=x86: This yields an x86-pc build.
  • TUT_BOARD=pc, TUT_ARCH=x86_64: This yields an x86_64-pc build.
  • TUT_BOARD=zynq7000: This yields an armv7-zynq7000 build.

Other boards may work, and the hello-1, hello-2, hello-3 and hello-4 tutorials should work on most boards. Hello-timer may not work on many boards.

After selecting your target machine and tutorial please type ninja to compile and then look for your compiled images inside of the subfolder images within your build directory.

Power up your favourite emulator or transfer the images to your target board, and enjoy!

Virtual Machine Image

You can also download a VirtualBox virtual machine appliance(md5) (3GB, based on Lubuntu 16.04.1 with all the seL4 tutorial prerequisites installed).

This appliance is based on VirtualBox 5.1.2.
You may also need to install the appropriate VirtualBox extensions.

Tutorial Code

The tutorial exercises are available in apps. This directory contains partially completed code and comments on how to complete it. Sample solutions are available in solutions.

To get a copy of the seL4 API and library exercise code and all libraries and tools needed to build and run it do the following:

    mkdir sel4-tutorials
    cd sel4-tutorials
    repo init -u http://github.com/SEL4PROJ/sel4-tutorials-manifest -m sel4-tutorials.xml
    repo sync

To get a copy of the CAmkES exercise code and all libraries and tools needed to build and run it do the following:

    mkdir camkes-tutorials
    cd camkes-tutorials
    repo init -u http://github.com/SEL4PROJ/sel4-tutorials-manifest -m camkes-tutorials.xml
    repo sync

Reporting issues or bugs in the tutorials:

Please report any issues you find in the tutorials (bugs, outdated API calls, etc) by filing an issue on the public github repository: https://github.com/SEL4PROJ/sel4-tutorials/issues

Documentation

Developer wiki

A walkthrough of each tutorial is available on the wiki

Tutorial Slides

The slides used for the tutorial are available in docs.

seL4 Manual

The seL4 manual lives in the kernel source in the manual directory. To generate a PDF go into that directory and type make. You will need to have LaTeX installed to build it.

We've also included a pre-generated PDF version in `docs/manual.pdf'

CAmkES Documentation

CAmkES documentation lives in the camkes-tool repository in docs/index.md.
