Build Kernel

Build for RSB4710 platform

$ cd $TOP
$ cd kernel
$ make ARCH=arm64 rk3399_adv_defconfig -j8
$ make ARCH=arm64 rk3399-rsb4710-a2.img -j12

Build Recovery

$ cd $TOP
$ rm buildroot/output/rockchip_rk3399_recovery -rf
$ source envsetup.sh rockchip_rk3399_recovery
$ ./build.sh recovery

Build Debian 9.x

$ source build/envsetup.sh 
$ lunch rk3399_rsb4710-userdebug
$ make -j4 2>&1 | tee build-log.txt

Build ubuntu 16.04

$ source build/envsetup.sh 
$ lunch rk3399_rsb4710-userdebug
$ make -j4 2>&1 | tee build-log.txt

Push all image to rockdev folder

$ ./mkimage.sh

All image in rockdev/Image-rk3399_rsb4710 ./mkimage.sh at previous step will repack boot.img and system.img, and copy other related image files to the rockdev/Image-rk3399_rsb4710/ directory. The common image files are listed below:

# boot.img         : Android's initramfs, to initialize and mount system partition. 
# kernel.img       : Kernel image.
# misc.img         : Misc partition image, to switch boot mode and pass parameter in recovery mode.
# recovery.img     : Recovery mode image.
# resource.img     : Resource image, containing boot logo and kernel's device tree info.
# system.img       : System partition image with ext4 filesystem format.
# uboot.img        ：uboot
# trust.img        ：File about sleep
# MiniLoaderAll.bin ：Loader

Create OTA zip

Step1 After Build Android, you will be create image for OTA update.

$ ./mkimage.sh ota

Step2 Package the update.zip

$ make otapackage

Step3 Rename the out/target/product/rk3399_rsb4710/rk3399_rsb4710-ota-eng.adv.zip to update.zip

$mv out/target/product/rk3399_rsb4710/rk3399_rsb4710-ota-eng.adv.zip update.zip

Note :  "adv" in rk3399_rsb4710-ota-eng.adv.zip  is the name of your building PC.

Step4 Copy the update.zip to SD or USB disk.

Step5 Follow Android update.
