I followed the below instructions to build android kernel for hikey960
git clone kernel/hikey-linaro - Git at Google
cd hikey-linaro
git checkout -b android-hikey-linaro-4.9 origin/android-hikey-linaro-4.9
build.sh
ANDROID_HOME=/home/root/hikey-linaro/hikey_android_repo
KERNEL_HOME=/home/root/hikey-linaro/hikey_android_repo/hikey-linaro
PRODUCT_OUT=${ANDROID_HOME}/out/target/product/hikey960
RAMDISK_IMG=${PRODUCT_OUT}/ramdisk.img
cd ${KERNEL_HOME}
make ARCH=arm64 hikey960_defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- -j24
cd ${ANDROID_HOME}
cp -f hikey-linaro/arch/arm64/boot/Image.gz Image.gz-hikey960
cp -f hikey-linaro/arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dtb device/linaro/hikey-kernel/hi3660-hikey960.dtb
make bootimage -j64
./mkbootimg --kernel Image.gz-hikey960 --ramdisk ${RAMDISK_IMG} --cmdline “loglevel=15 androidboot.hardware=hikey960 androidboot.selinux=permissive firmware_class.path=/system/etc/firmware” --base 0x0 --tags-addr 0x07A00000 --kernel_offset 0x00080000 --ramdisk_offset 0x07c00000 --output ${PRODUCT_OUT}/boot.img
mkdtimg -d hi3660-hikey960.dtb -s 2048 -c -o ${PRODUCT_OUT}/dt.img
echo “dt.img boot.img build finished!”
Flash the boot & dt binaries
fastboot flash boot ${PRODUCT_OUT}/boot.img
fastboot flash dts ${PRODUCT_OUT}/dt.img
But with the above steps, it is crashing during init stage :

Any step have i missed to do ? Also generated system.img, vendor.img and updated those bins as well
Thanks in advance
