Android BSP Version

Android 9.0.0_r35

Introduction

This document describes how to work with the RISC and ELAA Android 9.0.0 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

Required equipment and software

• Ubuntu 16.04 LTS 64bit for Android build host OS
• 130G bytes free disk spaces for build image

Install Ubuntu

• 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.

Run Docker example

Step1 Run docker container (example)

 $ docker run -it --name android_p9 -v /home/bsp/myandroid:/home/adv/BSP:rw advrisc/u16.04-imx6abv6 /bin/bash

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

Install docker and Use docker

Please use docker environment to compiler Android 9.0.0

• Android 9.0.0 Docker
• Image Repository : advrisc/u16.04-imx6abv6
• Image Tag : lastest

Reference: [3]

To pull Docker image from Docker Hub

• docker pull advrisc/u16.04-imx6abv64
• docker run --name imx6ABV64 -it advrisc/u16.04-imx6abv64 /bin/bash

Getting Android Source Code

Related version information:

• Android 9.0.0_r35
• kernel Yocto-2.5
• U-Boot Yocto-2.5

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

$ git config --global user.name "Your Name" 
$ git config --global user.email you@example.com

$ mkdir myandroid
$ mkdir bin
$ cd myandroid/
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ../bin/repo
$ chmod a+x ../bin/repo
$ ../bin/repo init -u https://github.com/ADVANTECH-Corp/android-manifest.git -b p9.0.0_2.2.0-ga
$ ../bin/repo sync

$ cd ~/myandroid/vendor/nxp-opensource/uboot-imx/
$ patch -p1 < ../../../patches_android_9.0.0_r35/9001-Uboot_Yocto_4.14.98_2.0.0-to-android-9.0.0_r35.patch 
$ cd ~/myandroid/vendor/nxp-opensource/kernel_imx/ 
$ patch -p1 < ../../../patches_android_9.0.0_r35/9001-Linux_Yocto_4.14.98_2.0.0-to-android-9.0.0_r35.patch 
$ cd myandroid

Building Android 9.0.0 image for SD card

If your product is RSB-4411A1, the product name is rsb_4411_a1

$PRODUCT = rsb_4411_a1

If your product is ROM-5720, the product name is rom5720_a1

$PRODUCT = rom5720_a1

If your product is RSB-4411A1, the product name is rom7720_a1

$PRODUCT = rom7720_a1

Build Instructions

Set the $JAVA_HOME environment variable

$ export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/

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

$ source build/envsetup.sh

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 RSB4411, you will be send command " lunch rsb_4411_a1-user

$ lunch $PRODUCT-user

To build boot loader

Perform the following command in terminal console

$ make 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 boot image

Perform the following command in terminal console

$ make bootimage -j8

To build dtbo image (kernel device tree)

Perform the following command in terminal console

$ make dtboimage -j8

To build system image

Perform the following command in terminal console

$ make -j8

Burning image

Go to those built image file directory

For daily build

$ cd ~/image/

For local build

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

Enter flash command

$ sudo ./fsl-sdcard-partition.sh -f imx6q /dev/sdX (X : SD card device drive)

Flash adv bootloader (This is only for i.MX6)

For daily build

$ sudo dd if=u-boot_crc.bin.crc of=/dev/sdX bs=512 seek=2 conv=fsync (X : SD card device drive)
$ sudo dd if=u-boot_crc.bin of=/dev/sdX bs=512 seek=3 conv=fsync (X : SD card device drive)

For local build

$ sudo dd if=obj/UBOOT_OBJ/u-boot_crc.bin.crc of=/dev/sdX bs=512 seek=2 conv=fsync (X : SD card device drive)
$ sudo dd if=obj/UBOOT_OBJ/u-boot_crc.bin of=/dev/sdX bs=512 seek=3 conv=fsync (X : SD card device drive)

Display Configuration

HDMI Display

setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 consoleblank=0 vmalloc=128M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off androidboot.hardware=freescale cma=448M

Dual Display (VGA+HDMI)

(If kernel parameter is too long, the DUT may stop at init step during boot up, please remove adv_boot parameter before configuring dual display).

setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 consoleblank=0 vmalloc=128M init=/init video=mxcfb0:dev=lcd,fbpix=RGB32,bpp=32 video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb2:off video=mxcfb3:off androidboot.hardware=freescale cma=320M galcore.contiguousSize=33554432 loop.max_part=7

Know Issue

• The bootargs in the kernel parameter is not defined. Please enter the following text in the bootloader. Otherwise, this device won't boot up success.

setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 consoleblank=0 vmalloc=128M init=/init androidboot.hardware=freescale cma=448M galcore.contiguousSize=33554432 loop.max_part=7

• Make sure there are one of the input devices be plugged in DUT. The input service will always watch /dev/input node.
