This Partner Demo Image makes it easy for you to evaluate QNX on Toradex Computer on Modules since you can deploy a pre-compiled binary image to the hardware in a few steps. It is also a great starting point since it saves time and costs since you don't need to port a BSP from zero but instead use the BSP source-code to add your customizations on top.
there are QNX BSP ports available for other Toradex Computer on Modules in addition to the one supported by this Partner Demo Image. Learn more about all supported SoMs on the QNX software page.
The pre-built evaluation image is provided as-is by Toradex, meant for evaluation only, and it may be suitable for application development as long as you don't need extra dependencies. It is built from the QNX BSP provided by BlackBerry/QNX to Toradex. Read the Detailed Information and Additional Resources on the QNX software page for more details.
It is expected that you customize the BSP, build, and validate your own image before production.
How to Get Started
This section provides instructions for you to get started with QNX quickly.
- Toradex supported hardware as listed in the Supported Hardware and Features.
- It is mandatory to use a compatible Apalis Heatsink Fan, otherwise the graphics package may crash after running for a long period of time.
Get and Prepare the Image
Contact our sales team to get access to the image.
Unpack the image into the root directory of a FAT32 formatted micro SD Card or USB stick, then insert the media into the Ixora Carrier Board.
Flash the Image to the Computer on Module
Load the Toradex Easy Installer on the target module and select QNX from the list of available images.
Once the installation is done, power-off the board and make sure that you have access to the debug UART. Instructions and parameters are the same as from Configuring Serial Port Debug Console (Linux/U-Boot).
Power-on the board, and it will boot to a terminal on the debug UART interface:

Get the Board IP
Since QNX is a Unix-like OS, it has several utilities well-known for Linux users. For instance, given that you have an Ethernet cable plugged to the carrier board, to get your board IP you can run
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33136
inet 127.0.0.1 netmask 0xff000000
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
fec0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

inet6 fe80::38a9:5dff:fecc:2173%fec0 prefixlen 64 scopeid 0x11
In the example above, the IP is
Hello World Deploy and Debug
This section explores how to deploy and debug a Hello World application to the board. Please note that our summarized instructions don't replace the comprehensive QNX instructions and documentation. If you have questions, search on the QNX documentation.
Register for a QNX SDP License
To deploy and debug your own Hello World application, you need a QNX Software Development Platform (SDP) 7.0 license. You can get a trial from the 30 Day Evaluation on the QNX website. Instructions are provided on the page.
Install the QNX Software Center
Follow the instructions from QNX to download and install the QNX Software Center (QSC).
Install the QNX Software Development Platform (SDP) 7.0
you must install SDP 7.0. If you install 7.1 or newer, things may not work.
Open the QNX Software Center and install the SDP 7.0. Follow the QNX SDP Documentation for details. See a summary of the instructions below:
Make sure to select
aarch64le from the Target Architectures, as this is the Apalis iMX8 architecture.
Install the QNX Momentics IDE
Application development for QNX is done with the Momentics IDE. It is also installable from the QNX Software Center with few clicks:
Configure a Target Device
Open the Momentics IDE. It can be launched from the QNX Software Center:
On previous steps, you have discovered the board IP address from the QNX command line. You will use it to configure the target device on Momentics.
Once the target is configured, you can switch to the QNX System Information perspective of the IDE to check if the device connection was successful. See a summary of the steps below:
Create a Hello World from Template
On Momentics, create a new QNX Project > QNX Executable named
hello-world for the CPU Variant
aarch64le. On the configuration bar on the top on the IDE, select Debug, the hello-world project, and the board you've set up on the previous step, then click on the Debug button and the IDE will deploy the binary to the board and run it:
All support for the QNX software is done through our network of accredited partners, including BlackBerry/QNX. Toradex does not provide in-house technical support for your QNX. However, we are happy to help you get in touch with our partners if you need to. To know more, select the most suitable partner from the Toradex Partners (QNX) and fill the contact form provided on the respective partner page, or contact our sales team.
For more information about how to do QNX development head over to the extensive partner documentation.
You must do some customization on the BSP, even if only to prepare the system for production by e.g. removing debug features. You can do it by yourself or through one of our proven partners, including QNX themselves. To get the QNX BSP source-code for Apalis iMX8QM, you must contact our sales team.
Application Development, IDE Usage, Training, and More
The QNX documentation is a great starting point. QNX also provides training, if you are interested get in contact with our sales team and they will connect you to the closest QNX sales representative.
Graphical User Interface
Popular graphical frameworks are ported to run on QNX. Our partners provide some of them:
You must contact our partners to learn more about how to run their framework on QNX.
