Introduction
============
DistroKit is a Board Support Package (BSP) for the `PTXdist
<http://www.ptxdist.org>`_ build system. It assembles a small (but not
minimalistic) Embedded Linux system with modern components:
- barebox bootloader
- mainline kernel, as patch free as possible
- systemd based init
- NetworkManager for dbus based network configuration
It can be used as a base for further BSP development.
DistroKit supports multiple hardware platforms, see chapter
:ref:`hardware-platforms` for more information about them.
Quick Start
-----------
The next sections below describe briefly how to build the BSP from scratch,
but for more in-depth documentation, refer to the `PTXdist manual
<https://www.ptxdist.org/doc/>`_ (or the later chapters if you're reading this
documentation in the HTML or the PDF version).
If you already have a working environment, you can skip to the section about the
individual :ref:`hardware-platforms` for more information on how to build
images, how to flash an image to a board, or how to get a serial console.
Installing PTXdist
~~~~~~~~~~~~~~~~~~
DistroKit is built with PTXdist version |ptxdistVendorVersion|. In order to
install PTXdist,
`download the tarball <http://www.pengutronix.de/software/ptxdist/download/ptxdist-|ptxdistVendorVersion|.tar.bz2>`_
from the PTXdist Download Area.
Extract the tarball:
::
$ tar xf ptxdist-|ptxdistVendorVersion|.tar.bz2 && cd ptxdist-|ptxdistVendorVersion|
Go to the extracted directory and run
::
$ ./configure && make && sudo make install
Installing the Toolchain
~~~~~~~~~~~~~~~~~~~~~~~~
In order to build a BSP for a different architecture than your host system,
you need a toolchain.
DistroKit is configured for the OSELAS.Toolchain |oselasTCNVendorVersion|.
Depending on the platform you want to build, different toolchains are necessary –
see the sections about the :ref:`hardware-platforms`.
Pre-built Debian packages of the toolchains are available from Pengutronix,
but you can also build the toolchain from source.
See the `OSELAS.Toolchain homepage <https://www.pengutronix.de/de/software/toolchain.html>`_
for more information.
Contributing
------------
The canonical source repository for DistroKit is at
<https://git.pengutronix.de/cgit/DistroKit/>.
For any questions regarding DistroKit, send a mail to the mailing list at
<distrokit@pengutronix.de>.
Note that posts from non-subscribed addresses will be held for moderation.
We recommend that you subscribe to the list by sending a mail to
<distrokit-request@pengutronix.de> containing "subscribe" in the subject.
The same list should also be used to send patches.
The easiest way to format your patch into the canonical patch format is by
using `git format-patch <https://git-scm.com/docs/git-format-patch>`_ on the
DistroKit git repository
(also see its man page for info on using mailers other than *git send-email*).
