*Install on the target pre-built additional packages.
Different Depending on the specific task, a different types of cross-build processes can be process is used. In general, the following are of interest:*#Building software modules individually (i.e. without using the Yocto build system)*#Generating**The images the image including the U-Boot binary file, the Linux kernel image, and the root file system image (this process is based on the Yocto build system)**The #Generating the SDK associated with a specific root file system image*#Building a user applications application against a specific SDK. The overall development flow of a user application is depicted in the following image. For example, the last step shown in the diagram is performed by the second build process of the previous list.

===Building software modules individually===
This kind of build processes makes use of a pre-built cross-toolchain. To use it, the shell environment has to be set up properly first. To do this, just issue the following command:
