Generic Petalinux Dockerfile

A somehow generic Xilinx PetaLinux 2020+ docker file, using Ubuntu (though some tweaks might be possible for Windows).

It was successfully tested with version 2022.2.

Inspired by docker-xilinx-petalinux-desktop (and some of petalinux-docker).

Petalinux installer

Download PetaLinux installer from Xilinx/AMD website.

N.B. Petalinux 2022.2 installer is named petalinux-v2022.2-10141622-installer.run so you want to either rename it to petalinux-v2022.2-final-installer.run or create a link.

Build the image

Building the image requires a local HTTP server to serve big resources instead of pushing them to the Docker daemon so make sure the firewall is configured appropriately to allow incoming connections on docker network link tcp:172.17.0.1:8000, e.g.:

sudo ufw allow from 172.17.0.0/16 to 172.17.0.1

Run:

./docker_build.sh <VERSION>

<VERSION> can be 2022.2, ... Corresponding petalinux and SDK files are expected to be found in resources directory.

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

The image takes a some time to build, but should succeed.

It weighs around 12 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 2022.2.

• 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 installer.
  Defaults to http://172.17.0.1:8000/resources.

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

docker build . -t petalinux:2022.2 \
    --build-arg XILVER=2022.2 \
    --build-arg PETALINUX_INSTALLER=petalinux/petalinux-v2022.2-10141622-installer.run \
    --build-arg HTTP_SERV=https://local.company.com/dockers/petalinux/2022.2/resources

Petalinux at https://local.company.com/dockers/petalinux/2022.2/resources/petalinux/petalinux-v2022.2-10141622-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 and SDK settings.sh already sourced, so you can directly execute petalinux-* commands.

user@host:/path/to/petalinux_project$ /path/to/petalin.sh
petalinux@a3ce6f8c:/path/to/petalinux_project$ petalinux-create -t project --template zynq -n <project name>
petalinux@a3ce6f8c:/path/to/petalinux_project$ petalinux-config --get-hw-description <...>
petalinux@a3ce6f8c:/path/to/petalinux_project$ petalinux-build

Otherwise, the arguments will be executed as a command.

N.B. the SDK and PetaLinux settings.sh will not be sourced when running commands:

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

will fail because petalinux-build is not part of the path. But you can create your own script and start it instead:

# mbuild.sh
. /opt/petalinux-v2018.2-final/settings.sh
petalinux-build

then:

user@host:/path/to/petalinux_project$ /path/to/petalin.sh ./mbuild.sh
