Description

This property is used to define the memory allocation type the platform should use while accessing the binary resources. It is useful if the board offers different volatile memory (for example RAM, VRAM or HyperRAM) alternatives, or supports different memory allocation strategies.

The property takes an integer value between 0 to 255 inclusive. The given value should match the memory allocator types known by the platform. On most platforms the range, [128,255], is dedicated to user-defined custom allocators.

If a target board supports custom runtime allocation types, they will be described in the board-specific documentation.

The default value varies depending on the resource cache policy configured. If the policy is OnStartup, the default value is 3 (DefaultPreload). The accepted values are defined in AllocationType.

Usage

This property is accepted in the main application .qmlproject file, or a module .qmlproject file. It takes an integer.

Code example:

BinaryFiles {
    MCU.resourceRuntimeAllocationType: 129
}

MCU.Config {
    resourceRuntimeAllocationType: 129
}

Since

This property was introduced in Qt Quick Ultralite 2.9.
