7.2 MSC-LDK (Yocto)
7.2.1 MSC-LDK Terms
• The Yocto-based MSC-LDK uses a sophisticated approach to generate Linux images.
• A target is the hardware or CPU module on which the generated Linux software is to be run.
• An image contains all the files necessary for execution by the targeted hardware, e.g. the Linux kernel and the root filesystem.
• Software that is part of a Linux image is called a package.
• A package is generated from sources by a recipe, which is a description of where to download the sources and how to compile them within
Yocto.
• A layer is a collection of recipes. They are stackable and can extend or modify recipes defined in other layers. A BSP provides the necessary
layers to MSC-LDK to support the target’s hardware.
• MSC-LDK is mainly an installer of Yocto, MSC specific layers and BSP layers.
