Step1 Run docker container (example)

docker run --privileged -it --name android_S12 -v /home/your-name/myandroid:/home/adv/BSP:rw advrisc/u18.04-rk3399abv10 /bin/bash

Step2 In container, change the user. (example)

 

$ sudo chown adv:adv -R BSP

How to update images?

There are three ways to update images：

(The corresponding tools are in the RKTools/ directory of the source code)

1._Using_AndroidToool.

There is no limitation by this way.

2._Using_storage（such sd_or_USB_disk）with_update.zip_in_it.

There are some limitations：

（1）The device must be able to boot up to Android system.

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

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

（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.

（2）Using update.img to upgrade.
