Using Safety-Critical Items in Qt Quick Ultralite Applications

With Qt Safe Renderer 2.2.0,  you can use safety-critical items in Qt Quick Ultralite applications. You should use Qt Safe Renderer 2.2 together with the Qt for MCUs 2.12 release. 

The following Qt Safe Renderer 2.2 documentation pages provide more information about new features in the release:

• Getting Started with Qt Safe Renderer and Qt Quick Ultralite
• Building for Qt Quick Ultralite
• Qt Safe Monitor: Qt Quick Ultralite Example on Bare-Metal Traveo II demonstrates how to integrate Qt Safe Renderer Monitor into a Qt Quick Ultralite application targeting a bare-metal Infineon Traveo II environment.
• Related API changes are listed in Changes to QSR Runtime API

See also the MCU 2.12 online documentation and its instructions on how to create a Qt Quick Ultralite application with safety-critical items. 

Alpha Pixel Bypass for Transparent Backgrounds

Alpha Pixel Bypass feature is available for Snapdragon Generation 4 hardware (Qualcomm Snapdragon 8295). This feature enables output verification for safe items with transparent backgrounds by excluding pixels with alpha values from the CRC calculations. For more information, see Alpha Pixel Bypass for Transparent Backgrounds.
