Buildroot Output Directory
After the compilation is complete, a subdirectory will be generated in the compilation output directory output/rockchip_rk3568 as follows:
build/contains all source files, including the required host tools and selected packages for Buildroot. This directory contains all package source code.host/Tools required for host-side compilation include cross-compilation tools.images/contains a compressed root filesystem image file.staging/This directory is similar to the directory structure of the filesystem. It contains all the header files and libraries generated by the compiler, as well as other development files, but they are not tailored and are too large to be used for the target filesystem.target/contains the complete root filesystem. Compared tostaging/, it has no development files, no header files, and the binary files arestripprocessed.
