  • Clone source code

    git clone https://github.com/meisreallyba/padavan-4.4.git

  • Prepare toolchain

    cd padavan-4.4/toolchain-mipsel
    
    # (Recommend) Download prebuilt toolchain for x86_64 or aarch64 host
    ./dl_toolchain.sh
    
    # or build toolchain with crosstool-ng
    # ./build_toolchain

  • Modify template file and start compiling

    cd padavan-4.4/trunk
    
    # (Optional) Modify template file
    # nano configs/templates/K2P.config
    
    # Start compiling
    fakeroot ./build_firmware_modify K2P
    
    # To build firmware for other devices, clean the tree after previous build
    ./clear_tree
