Install Dependency Packages
Execute the following command to download the dependency
                packages:
    ./scripts/feeds update -a ./scripts/feeds install -a make download V=s
Note: The download process may
                take a long time, please be patient. If a 
download failed error
                occurs during the process, it indicates that the software package has not been fully
