We are pleased to announce a Yocto release for our Nitrogen8M Nano SBC based on the i.MX8M NANO 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
In addition, you can use the etcher utility to flash the SD Card or USB stick via Windows or Linux:
This image uses the zeus branch of our boundary-bsp-platform repository.
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-nano && cd yocto-imx8m-nano ~/yocto-imx8m-nano$ repo init -u http://github.com/boundarydevices/boundary-bsp-platform -b zeus ~/yocto-imx8m-nano$ repo sync
Setup the environment for building, in this example we will be building our boundary-wayland distro for Nitrogen8m Nano
~/yocto-imx8m-nano$ MACHINE=nitrogen8_2eth 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-nano/build$ bitbake boundary-image-multimedia-full
After some time this should build the same image as above.
The image file will deploy to
The image built above contains the following components:
- GPU Vivante libraries 6.2.4p4.0
- GStreamer1.0 1.14.0 for i.MX
- Weston 5.0.0 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.
Please make sure your platform includes the latest U-Boot for i.MX8M MINI:
This version of U-Boot supports the display configuration, allowing to use any of the following displays:
In order to test the GPU, you can either use the standard Weston EGL programs or the ones provided by Vivante.
Here are a few examples:
root@nitrogen8mm:~# weston-simple-egl & root@nitrogen8mm:~# cd /opt/viv_samples/vdk/ root@nitrogen8mm:/opt/viv_samples/vdk# ./tutorial7
Camera MIPI-CSI input can be checked using our OV5640 MIPI with GStreamer:
root@nitrogen8mm:~# gst-launch-1.0 v4l2src device=/dev/video0 ! \ video/x-raw,width=1280,height=720 ! glimagesink
eth0 interface is up, you can use ping to check internet connectivity:
root@nitrogen82eth:~# ping google.com -I eth0 PING google.com (22.214.171.124): 56 data bytes 64 bytes from 126.96.36.199: seq=0 ttl=56 time=12.117 ms 64 bytes from 188.8.131.52: seq=1 ttl=56 time=16.837 ms 64 bytes from 184.108.40.206: seq=2 ttl=56 time=21.280 ms ^C --- google.com ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 12.117/16.744/21.280 ms
eth1 interface is up, you can use ping to check internet connectivity:
root@nitrogen82eth:~# ping google.com -I eth1 PING google.com (220.127.116.11): 56 data bytes 64 bytes from 18.104.22.168: seq=0 ttl=56 time=14.271 ms 64 bytes from 22.214.171.124: seq=1 ttl=56 time=12.400 ms 64 bytes from 126.96.36.199: seq=2 ttl=56 time=18.015 ms ^C --- google.com ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 12.400/14.895/18.015 ms root@nitrogen82eth:~#
Same goes for the Wi-Fi that can be tested just as easily:
root@nitrogen8mm:~# nmcli d wifi connect <network_name> password <password> root@nitrogen8mm:~# iw wlan0 link Connected to a4:3e:51:08:54:f6 (on wlan0) SSID: Jabu_5GHz freq: 5240 RX: 3243 bytes (31 packets) TX: 9117 bytes (48 packets) signal: -79 dBm tx bitrate: 15.0 MBit/s MCS 0 40MHz short GI root@nitrogen8mm:~# ping google.com -Iwlan0 PING google.com (188.8.131.52): 56 data bytes 64 bytes from 184.108.40.206: seq=0 ttl=55 time=3.470 ms ...
You’ll be able to connect using these commands:

You’ll be able to bring up the interface using these commands:
root@nitrogen8mm:~# ip link set can0 up type can bitrate 500000 root@nitrogen8mm:~# ifconfig can0 up
From this point, you can use commands such as candsend and candump to send or display messages on the bus.
