Android BSP Version[edit]

Android 10.0.0_r35


This document describes how to work with the RISC and ELAA Android 10.0.0 Board Support Package (BSP) release. The BSP includes bootloaders; the Android Linux kernel and root file system; and tools and documentation to ease the development, deployment, and execution of Android-based systems.

Setup Ubuntu Host Computer[edit]

Required equipment and software[edit]

  • Ubuntu 18.04 LTS 64bit for Android build host OS
  • 130G bytes free disk spaces for build image

Install Ubuntu[edit]

  • IMPORTANT! You must be able to log in as root or use sudo to have root permissions during the installation.

Go to [1] and download 64-bit PC (AMD64) desktop image: [2] for the installation.

Docker install and setting

If you don't have docker in your system, then you can follow the below  steps to install docker and run it first.

To install Docker Engine on your platform

Please refer to Docker Installation Guide for details

To pull ubuntu 18.04 image from Docker Hub 

$ docker pull advrisc/u18.04-rk3399abv10

Run Docker example[edit]

Step1 Run docker container (example)

 $ docker run -it --name android_q10 -v /home/bsp/myandroid:/home/adv/BSP:rw advrisc/u18.04-rk3399abv10 /bin/bash

Step2 In container, change the user. (example)

 adv@7cc0fa834366:~$ sudo chown adv:adv -R BSP

Install docker and Use docker[edit]

Please use docker environment to compiler Android 10.0.0

  • Android 10.0.0 Docker
  • Image Repository : advrisc/u18.04-rk3399abv10
  • Image Tag : lastest

Reference: [3]

To pull Docker image from Docker Hub[edit]

  • docker pull advrisc/u18.04-rk3399abv10
  • docker run --name imx8ABV10 -it advrisc/u18.04-rk3399abv10 /bin/bash

Getting Android Source Code[edit]

Related version information:[edit]

  • Android 10.0.0_r35
  • kernel Yocto-3.0
  • U-Boot Yocto-3.0

Step1 : To pull down the Android source tree to your working directory from the repositories as specified in the default manifest

$ git config --global "Your Name" 
$ git config --global
$ mkdir myandroid

$ mkdir bin

$ cd myandroid/

$ curl > ../bin/repo

$ chmod a+x ../bin/repo

$ ../bin/repo init -u  -b q10.0.0_2.3.0-ga -m release_version.xml

$ ../bin/repo sync

=== The release_version.xml  as follows:
RSB3720 for RSB3720_Q10_AIV0002.xml

if you got the error " '': server certificate verification failed." , please use " export GIT_SSL_NO_VERIFY=1"   # 讓 Git Client 忽略 SSL 憑證檢查

Step2: Patch to Android Q10.0.0.0

$ cd ~/myandroid/vendor/nxp-opensource/uboot-imx/
$ patch -p1 < ../../../patches_android-10.0.0_r35/10001-Uboot_Yocto_5.4.24_2.1.0-to-android-10.0.0_r35.patch
$ cd ~/myandroid/vendor/nxp-opensource/kernel_imx/
$ patch -p1 < ../../../patches_android-10.0.0_r35/10001-Linux_Yocto_5.4.24_2.1.0-to-android-10.0.0_r35.patch
$ cd myandroid

Building Android 10.0.0 image for SD card[edit]

If your product is RSB-3720, the product name is rsb3720_a1

$PRODUCT = rsb3720_a1

Build Instructions[edit]

Set the $JAVA_HOME environment variable

$ export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/
$ export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-

Set up the environment for building. This only configures the current terminal.

$ source build/

Execute the Android lunch command. In this example, the setup is for the production image of Advantech RISC platfrom device with user type. If you devices is RSB-3720, you will be send command rsb3720_a1-userdebug

$ lunch $PRODUCT-userdebug

To build boot loader

Perform the following command in terminal console

$ ./ bootloader -j8

The two files, u-boot_crc.bin & u-boot_crc.bin.crc, will be located in directory, ./out/target/product/product_name

To build kernel

Perform the following command in terminal console

$ ./ kernel -j8

To build boot image

Perform the following command in terminal console

$ ./ bootimage -j4

To build dtbo image (kernel device tree)

Perform the following command in terminal console

$ ./ dtboimage -j4

To build system image

Perform the following command in terminal console

$ ./ -j8

Burning image[edit]

SD card boot[edit]

Go to those built image file directory

For daily build

$ cd ~/image/

For local build

$ cd ~/out/target/product/PRODUCT_NAME/

Enter flash command

For RSB-3720

$ sudo ./ -super -f imx8mp /dev/sdX (X : SD card device drive)

Image from SDCard to EMMC boot[edit]

You can get Downloads package for images(eg:RSB3720-androidQ10-AIV00XX-YYYYMMDD.tar.gz)

SDCard image

$ tar zxvf RSB3720-androidQ10-AIV00<span style="color:#FF0000">XX</span><span style="color:#000000">-</span><span style="color:#FF0000">YYYYMMDD</span>.tar.gz  (image/ and scripts/)
$ cd scripts/
$ sudo ./ -super -f imx8mp /dev/sdX (X : SD card device drive)

Starting OS for SDCard,on debug console,flash image to emmc

$ su
# cd /data/mkimage/scripts
# ./ -super -f imx8mp /dev/block/mmcblk2
