New page

== Android BSP Version ==

Android 12.0

Kernel 4.19.206

== Build Environment on Host ==

Currently, we adopt [https://www.docker.com/ Docker] as build environment.

You can get the latest version of [https://hub.docker.com/r/advrisc/u18.04-rk3399abv10 advrisc/u18.04-rk3399abv10] Docker image for developing Rockchip RK3399 and rk3568 projects.

Docker command:
<pre>docker pull advrisc/u18.04-rk3399abv10:latest;</pre>

== Run Docker example ==

Step1 Run docker container (example)
<pre>docker run --privileged -it --name android_S12 -v /home/your-name/myandroid:/home/adv/BSP:rw advrisc/u18.04-rk3399abv10 /bin/bash
</pre>

Step2 In container, change the user. (example)

 
<pre>$ sudo chown adv:adv -R BSP
</pre>

== Getting Android Source Code ==
<pre>$ cd ~/BSP
$ sudo git clone https://github.com/ADVANTECH-Rockchip/repo.git
$ mkdir rk3568_android_S12
$ cd rk3568_android_S12
$ git config --global user.name &quot;Your Name&quot;
$ git config --global user.email you@example.com
$ git config --global http.postBuffer 52428800000
$ git config --global http.maxRequestBuffer 100M
$ git config --global core.compression 0
$ ../repo/repo init -u https://kag-sw.visualstudio.com/RK3568-Android/_git/android-manifest -b rk3568-androidS12 -m default.xml
------If you want to get the latest code, please use default.xml------
------If you want to get RSB4810 code, please use RK3568_S12_AIV12001.xml------
------If you want to get ROM5880 code, please use RK3568_S12_AIV12002.xml------
$ ../repo/repo sync -c -f --no-clone-bundle -j`nproc`
</pre>

== 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.|1._Using_AndroidToool.]]''' ===

There is no limitation by this way.

=== '''[[2._Using_storage（such_sd_or_USB_disk）with_update.zip_in_it.|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.|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.
