Supported Reference Devices
The Boot to Qt stack can be made to run on a variety of hardware. For Qt for Device Creation license holders, tooling is provided to customize the contents of the stack as well as to take it into desired production hardware. For more information on how to customize the stack for embedded Linux, see Building Your Own Embedded Linux Image.
Approximate minimal hardware requirements for running Boot to Qt are:
- 256 MB of RAM
- 500 MHz CPU, 1 GHz preferred for 60-FPS velvet-smooth UI
- OpenGL ES 2.0 support *
* On GPU-less hardware, Qt Quick 2D Renderer can replace the OpenGL ES 2.0 requirement (with some limitations on graphics capabilities).
Support Lifecycle Policy
The Qt Company will continue providing support for this release of Qt for Device Creation two years after the release date of a version that supercedes it.
Release dates and support end-of-life dates for each version are listed in the ChangeLog.
Emulator Support
Support for the emulator is limited to the Qt for Device Creation release and pre-compiled emulator images it shipped with. Using the emulator application to run images from previous releases is not supported.
Supported Device Groups
The reference devices are divided into three groups, based on level of support The Qt Company provides for the device:
Group 1
Qt is fully supported unless otherwise stated due to limitations on the platform level. Support can help with any issues relating to the Qt libraries and tools, but not the third party elements. Any problems found need to be reproducible with Qt libraries for further investigation by the support team.
Pre-compiled embedded Linux images for group 1 devices are available via the Qt online installer.

| Freescale® SABRE SD i.MX6Quad (Freescale® i.MX6) 4x ARM Cortex A9, Vivante GC2000 GPU, 1GB RAM |
| BeagleBone Black TIAM335x 1GHz ARM® Cortex-A8, 512 MB RAM |
| Boot to Qt Emulator Included in the development environment |
| Devices with GPU (Qt Automotive) |
| NVIDIA DRIVE™ CX Tegra X1 |
| Devices Without GPU |
| Toradex Colibri VF61 Dual-core (ARM Cortex-A5 + ARM Cortex-M4) solution with 1 MB on-chip SRAM |
| Toradex Colibri VF50 Single-core (ARM Cortex-A5) solution with 1.5 MB on-chip SRAM |
Group 2
Qt is fully supported unless otherwise stated due to limitations on the platform level. Support can help with any issues relating to the Qt libraries and tools, but not the third party elements. Any problems found need to be reproducible with Qt libraries.
If an issue is reproducible on either the desktop or a group 1 platform, then it will be investigated further by the support team. Otherwise, a bug report will be created, to be handled by the party responsible for the Qt port to the platform.
Pre-compiled images for group 2 devices are available via the Qt online installer.

| Intel® NUC Intel® Core i3, i5, or i7 Up to 32GB DDR4 Intel® Iris™ Graphics |
Group 3
No support provided. If a Qt related problem is found and reproducible with the Qt libraries on either desktop or a group 1 platform then it will be investigated further by the support team.
To use these devices, you need to build images by yourself or contact The Qt Company for consultancy services.
