Get Source Prepare and Build

mkdir /tmp/zero_builder
cd /tmp/zero_builder

git clone https://github.com/hyphop/miZy-linux-kernel.git
cd miZy-linux-kernel

./kernel_prepare
# ./kernel_config default 
./kernel_build_all

Custom config

./kernel_prepare light # arg is config file name => kernel-configs/light
./kernel_build_all

Easy make - by one-line command

wget http://raw.githubusercontent.com/hyphop/miZy-linux-kernel/master/make_it_easy -O- | sh -

output kernel

./bin
    Image           - unpacked kernel 
    uImage.gzip     - uboot gzip kernel image
    uImage.lzma     - uboot lzma kernel image, max compression, slow unpack time
    uImage.lzo      - uboot lzo  kernel image, fastest unpack time 
    uImage.none     - uboot none kernel image

output modules

./bin
    modules         - full 
    modules.all     - all in one dir
    modules.links   - all in one dir symlinks

Example u-boot mkimage packed kernel load script

...
# setenv kernel_file	"/boot/uImage.none"
# setenv kernel_file	"/boot/uImage.lzo"
# setenv kernel_file	"/boot/uImage.gzip"
setenv kernel_file	"/boot/uImage.lzma"
...
load mmc ${mmc_boot_part} ${kernel_addr_r} ${kernel_file}
...
bootm ${kernel_addr_r} ${ramdisk_addr_r}
...

Deps and cross compilation

• toolchain-arm_cortex-a9+neon_gcc-5.3.0_musl-1.1.15_eabi
• squashfs, overlayfs | aufs
• perl, mkimage ( u-boot-tools )
• lzop, gzip, lzma

its easy and automated by scripts!
