We’ve received many requests for Yocto support on our Nitrogen8M Mini SBC. Although this Yocto release isn’t tied to a specific version (Thud 2.6 not released yet), we believe it is still beneficial to release details on building a Yocto image for NXP’s i.MX 8MM application processor.
Below you will find the download link for the image as well as detailed instructions for the build including a features set.
For the Impatient
You can download the Yocto image from here:
As usual, you’ll need to register on our site and agree to the EULA because it contains NXP content.
The image is a SD card image that can be restored using zcat and dd under Linux.
~$ zcat *boundary-image*.wic.gz | sudo dd of=/dev/sdX bs=1M
For Windows users, please use Alex Page’s USB Image Tool.
Build procedure
We are currently working on the git repo for this image. Find the procedure below for when the git repo will be available:
This image uses the master branch of our boundary-bsp-platform repository.
This is mostly a clone of fsl-community-bsp-platform with meta-boundary added in.
To build the image, you’ll need these packages installed as well as this repo tool that can be installed like this:
~$ sudo apt-get install repo
Then create your build directory and initialize everything.
~$ mkdir ~/yocto-imx8m && cd yocto-imx8m ~/yocto-imx8m$ repo init -u http://github.com/boundarydevices/boundary-bsp-platform -b master ~/yocto-imx8m$ repo sync
Setup the environment for building, in this example we will be building our boundary-wayland distro for nitrogen8m.
~/yocto-imx8m$ MACHINE=nitrogen8mm DISTRO=boundary-wayland . setup-environment build
Now bitbake boundary-image-multimedia-full which is equivalent to fsl-image-multimedia-full with Boundary-specific packages such as BD-SDMAC support
~/yocto-imx8m/build$ bitbake boundary-image-multimedia-full
After some time this should build the same image as above.
The image file will deploy to tmp/deploy/images/{MACHINE}/boundary-image-multimedia-full-{MACHINE}.wic.gz.
Features list
The image built above contains the following components:
- GPU Vivante libraries 6.2.4p1.8
- VPU Hantro libraries v1.8.0
- GStreamer1.0 1.14.0 for i.MX
- Weston 4.0.0 for i.MX
- qcacld-2.0 Wi-Fi driver for BD-SDMAC
- BlueZ 5.50 with support for BD-SDMAC
The next sub-sections will describe how to test most features.
