The Boot to Qt Software Stack is designed for versatile customization possibilities:

You can use the Yocto tools to build custom Boot to Qt images for a target device that is already supported by Boot to Qt. By building a custom image, you can have control over which packages are included in the build and how the software stack is configured. For more information, see How to Create Boot to Qt Image and topics under How to Customize a Boot to Qt Image.

If you are developing software for a target device that is not yet supported in your Boot to Qt for embedded Linux environment, you can add the support by including the required Yocto BSP layer, that is, a new integration meta layer. For more information, see Creating New Integration Meta Layer.

Qt Board Support Package (QBSP) is an extension to the Qt online installer using Qt Installer Framework. It provides a way to deliver and install additional content that is not directly available from the online repositories. To provide access to your customized content, you can build your own QBSP files. For more information, see Building QBSP with Yocto.
