The following instructions show how to download and build the current release.
Follow the instructions here: https://gerrit.googlesource.com/git-repo/+/HEAD/README.md
Follow the instructions here: https://docs.yoctoproject.org/5.2.2/singleindex.html#build-host-packages
Use the i.MX Linux BSP manifest repository to create the Yocto Project layers.
$: repo init -u https://github.com/nxp-imx/imx-manifest.git -b imx-linux-walnascar -m imx-6.12.34-2.1.0.xml
$: repo sync
To setup a new build folder called build, run i.MX Linux Yocto Project Setup:
$: [MACHINE=<machine>] [DISTRO=<distro>] source ./imx-setup-release.sh -b build
where
<distro> defaults to fsl-imx-xwayland
<machine> defaults to imx6qsabresd
The NXP i.MX End User License Agreement (EULA) is displayed during the setup process. Please read it carefully. The license must be accepted to allow access to the NXP EULA-licensed recipes.
Depending on the i.MX Series, the BSP supports different graphics backends and different distros to highlight those.
| Series | Distro Name | Description |
|---|---|---|
| 6 and 7 | fsl-imx-fb | Framebuffer backend |
| 6-9 | fsl-imx-wayland | Weston desktop on Wayland backend, includes framebuffer support |
| 6-9 | fsl-imx-xwayland | Weston desktop on Wayland backend, includes framebuffer and XWayland support |
In order to configure a Linux shell for building in an existing build folder:
$: cd <build folder>/..
$: source ./setup-environment <build folder>
Three different images are provided in the distribution layer.
| Image Name | Description |
|---|---|
| imx-image-core | base image with Weston desktop |
| imx-image-multimedia | imx-image-core plus multimedia |
| imx-image-full | imx-image-multimedia plus Qt and machine learning |
Here's an example:
$: bitbake imx-image-full
