docker-petalinux

DOI

A somehow generic Xilinx PetaLinux & Vivado docker file, using Ubuntu (though some tweaks might be possible for Windows).

It was successfully tested with version 2018.3 and 2019.1, which is the last version handled by this release. For more recent versions, please check docker-petalinux2.

Inspired by docker-petalinux, docker-xilinx-petalinux-desktop, and petalinux-docker.

Prepare installers

Petalinux installer

The PetaLinux installer needs to be downloaded from the Xilinx's Embedded Design Tools website. It needs to be prepared for unattended installation.

Run the installer and save the petalinux-vXXX.X-final-installer.run file in ./resources/

We need to patch the Petalinux installer so it does not ask to accept licenses.

N.B. I'm not sure it's completely legal; but I haven't been able to script an expect to automatically accept them (which might not be legal as well anyway). So we'll consider your download means you accept those licenses (which are available in the petalinux install directory)

Run:

cd resources
./patch_petalinux_installer.sh ./petalinux-vXXX.X-final-installer.run

(that will patch the installer in place).

Vivado installer

The Vivado installer needs to be downloaded from the Xilinx's Vivado Design Tools website. Go there and choose the All OS installer Single-File Download (TAR/GZIP).

The file is called something like Xilinx_Vivado_SDK_2018.3_XXXX_XXXX.tar.gz. The default value for XXXX_XXXX is 1207_2324, if the numbers differ you can change them in the Dockerfile or passing an argument in the docker_build.sh script.

Please place this file in the ./resources/ folder.

Build the image

Run:

./docker_build.sh <VERSION>

<VERSION> can be 2018.3 or 2019.1, ... Corresponding petalinux installer is expected to be found in a ./resources directory. The default for <VERSION>, if not specified, is 2018.3.

The docker_build.sh will automatically spawn a simple HTTP server to serve the installer instead of copying it to the docker images (especially pushing them to the Docker daemon. Big space/time saver).

The image takes a long time to build (on the order of hours, depending on disk space and system use) but should succeed.

It weighs around 45 GB.

Parameters

Several arguments can be provided to customize the build, with --build-arg:

  • XILVER for the Xilinx version to install. The Dockerfile expects to find ${HTTP_SERVER}/petalinux-v${XILVER}-final-installer.run for the PetaLinux installer (unless PETALINUX_INSTALLER is given).
    Defaults to 2018.3.

  • PETALINUX_BASE is the name of the PetaLinux base. Petalinux will be installed in /opt/${PETALINUX_BASE} and the installer is expected to be sourced from resources/${PETALINUX_BASE}-installer.run.
    Defaults to petalinux-v${XILVER}-final.

  • PETALINUX_INSTALLER is the PetaLinux installer file.
    Defaults to ${PETALINUX_BASE}-installer.run

  • HTTP_SERV is the HTTP server serving both SDK and PetaLinux installers.
    Defaults to http://172.17.0.1:8000/resources.

  • XXXX_XXXX is the identifier of the Vivado Installer (which name isXilinx_Vivado_SDK_${XILVER}_${XXXX_XXXX}.tar.gz).
    Defaults to 1207_2324.

You can fully customize the installation by manually running e.g.:

docker build . -t petalinux:2018.3 \
    --build-arg XILVER=2018.3 \
    --build-arg PETALINUX_INSTALLER=petalinux/petalinux-v2018.3-final-patched.run \
    --build-arg HTTP_SERV=https://local.company.com/installers

Petalinux will be retrieved at https://local.company.com/installers/petalinux/petalinux-v2018.3-final-patched.run

Work with a PetaLinux project

A helper script petalin.sh is provided that should be run inside a petalinux project directory. It basically is a shortcut to:

docker run -ti -v "$PWD":"$PWD" -w "$PWD" --rm -u petalinux petalinux:<latest version> $@

When run without arguments, a shell will spawn, with PetaLinux settings.sh and Vivado settings64.sh already sourced, so you can directly execute petalinux-* commands and Vivado.

user@host:/path/to/petalinux_project$ /path/to/petalin.sh
petalinux@host:/path/to/petalinux_project# petalinux-build
petalinux@host:/path/to/petalinux_project# vivado

Otherwise, the arguments will be executed as a command. Example:

user@host:/path/to/petalinux_project$ /path/to/petalin.sh \
"petalinux-create -t project --template zynq --name myproject"

For Vivado, you might need some tweaking to get the graphical interface working. See section down below.

If you want to use repo, you will need to switch to Python 3.6, and then switch back to Python2.7 after using it:

# sudo update-alternatives --config python

Select Python 3.6 (option number 2), and then use repo (repo init ..., repo sync). When finished, switch back to Python 2.7 in order to use the petalinux-* commands:

# sudo update-alternatives --auto python

Using Vivado graphical interface

There are some steps on your side if you want to make use of Vivado's graphical interface before running the Docker container.

  • If your local machine is running Linux, adjust the permission of the X server host:

    $ sudo apt-get install x11-xserver-utils
$ xhost +local:root

  • If your local machine is running macOS:

    • Do this once:

    • Then, in the host machine:

       $ xhost + 127.0.0.1

  • If you are accessing remotely to the machine running the Docker container via ssh, you need to enable trusted X11 forwarding with the -Y flag:

    $ ssh user@host -Y

Now you can try it:

user@host:/path/to/petalinux_project$ /path/to/petalin.sh
petalinux@host:/path/to/petalinux_project# vivado

Enjoy!
