Download and build the kernel source

Please note that native kernel compile on ODROID-XU4 will take about 25 minutes.

target

$ git clone --depth 1 https://github.com/hardkernel/linux -b odroidxu4-4.14.y
$ cd linux
$ make odroidxu4_defconfig
$ make -j8
$ sudo make modules_install
$ sudo cp -f arch/arm/boot/zImage /media/boot
$ sudo cp -f arch/arm/boot/dts/exynos5422-odroid*dtb /media/boot
$ sync

target

$ sudo cp .config /boot/config-`make kernelrelease`
$ sudo update-initramfs -c -k `make kernelrelease`
$ sudo mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n uInitrd -d /boot/initrd.img-`make kernelrelease` /boot/uInitrd-`make kernelrelease`
