Usage: build_boot [OPTIONS]
|
|
Build openEuler SBCs boot image.
|
|
The target boot.img will be generated in the build folder of the directory where the build_boot.sh script is located.
|
|
|
|
Options:
|
|
--board BOARD_CONFIG Required! The config of target board in the boards folder, which defaults to firefly-rk3399.
|
|
-b, --branch KERNEL_BRANCH The branch name of kernel source's repository, which defaults to openEuler-20.03-LTS.
|
|
-k, --kernel KERNEL_URL Required! The URL of kernel source's repository.
|
|
-c, --config KERNEL_DEFCONFIG The name/path of defconfig file when compiling kernel, which defaults to openeuler_rockchip_defconfig.
|
|
--cores N The number of cpu cores to be used during making.
|
|
-h, --help Show command help.
