Reference/demo distribution for NVIDIA Jetson platforms using Yocto Project tools and the meta-tegra BSP layer.
Metadata layers are brought in as git submodules:
Layer Repo | Branch | Description |
---|---|---|
poky | master | OE-Core from poky repo at yoctoproject.org |
meta-tegra | master | L4T BSP layer - L4T R36.3.0/JetPack 6.0 |
meta-tegra-community | master | OE4T layer with additions from the community |
meta-openembedded | master | OpenEmbedded layers |
meta-virtualization | master | Virtualization layer for docker support |
See the Yocto Project Quick Build documentation for information on setting up your build host.
For burning SDcards (for Jetson Xavier NX developer kits), the bmap-tools
package is recommended.
Clone this repository:
$ git clone https://github.com/OE4T/tegra-demo-distro.git
Switch to the appropriate branch, using the wiki page for guidance.
Initialize the git submodules:
$ cd tegra-demo-distro
$ git submodule update --init
Source the setup-env
script to create a build directory,
specifying the MACHINE you want to configure as the default
for your builds. For example, to set up a build directory
called build
that is set up for the Jetson Xavier NX
developer kit and the default tegrademo
distro:
$ . ./setup-env --machine jetson-xavier-nx-devkit
You can get a complete list of available options, MACHINE names, and DISTRO names with
$ . ./setup-env --help
Optional: Install pre-commit hook for commit autosigning using $ ./scripts-setup/setup-git-hooks
Use the --distro
option with setup-env
to specify a distribution for your build,
or customize the DISTRO setting in your $BUILDDIR/conf/local.conf
to reference one
of the supported distributions.
Currently supported distributions are listed below:
Distribution name | Description |
---|---|
tegrademo | Default distro used to demonstrate/test meta-tegra features |
The tegrademo
distro includes the following image recipes, which
are dervied from the core-image-XXX
recipes in OE-Core but configured
for Jetson platforms. They include some additional test tools and
demo applications.
Recipe name | Description |
---|---|
demo-image-base | Basic image with no graphics |
demo-image-egl | Base with DRM/EGL graphics, no window manager |
demo-image-sato | X11 image with Sato UI |
demo-image-weston | Wayland with Weston compositor |
demo-image-full | Sato image plus nvidia-docker, openCV, multimedia API samples |
A swupdate demo image is also available which supports A/B rootfs updates to any of the supported images. For details refer to layers/meta-tegrademo/dynamic-layers/meta-swupdate/README.md.
