Push all image to rockdev folder

$ ./mkimage.sh

All image in rockdev/Image-rk3399_rsb4710 or rockdev/Image-rk3399_rom5780 ./mkimage.sh at previous step will repack boot.img and system.img, and copy other related image files to the rockdev/Image-project/ 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.

How to update images?

There are three ways to update images：

1._Using_AndroidToool.

There is no limitation by this way.

（3）Using update.zip to upgrade. (see more detail in "Create OTA zip" on how to create update.zip)

3._Using_bootup_sd_disk made_by SDDiskTool.

（1）Only update images from the same os,  eg : 

         Android6.0 upgrade to Android6.0 or Android7.1 upgrade to Android7.1.
