Welcome to the docker shell of Armbian.

To build the whole thing using default profile, run:
    ./compile.sh

To build the U-Boot only, run:
    # Optional: prepare the environment first if you had not run `./compile.sh`
    ./compile.sh 'prepare_host && compile_sunxi_tools && install_rkbin_tools'

    # build the U-Boot only
    ./compile.sh compile_uboot

If you prefer to use profile, for example, `userpatches/config-my.conf`,  try:
    ./compile.sh my 'prepare_host && compile_sunxi_tools && install_rkbin_tools'
    ./compile.sh my compile_uboot
