Andrews Android with its rich ecological environment, and fast application development and distribution, access to a wide range of market attention. Mir latest processor-based NXP iMX8 MYD-JX8MX core board and the development board also provides Android 9.0 support. Here we will introduce as from source to start compiling Andrews Android 9.0.
i.MX8 development board IntroductionPlease add a link description http://www.myir-tech.com/product/myc-jx8mx.htm
Deploy development environment
Development needs to be installed before the PC is good Linux operating system, is recommended for shooting Ubuntu 16.04 64bit release, 8G memory, 500G or more of free hard disk. Connecting a network cable and configured, the subsequent mounting operation requires an Internet connection or download package. NXP can refer to the official documentation "Android_User's_Guide.pdf".
Alternatively Ubuntu source software procedure is as follows:
1. the backup source /etc/apt/sources.list /etc/apt/sources.list-bak CP
2. Copy the contents of this /etc/apt/sources.list 16.04 Tsinghua source file.
3. Update Source apt-get update
PS: In case of appstream3 error can delete the packages before update.
Install the prerequisite packages
Newly installed Ubuntu system also need to install some commonly used software, execute the following command to install.
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsd l1.2-dev u-boot-tools
sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff cu rl lzop asciidoc Set repo file
repo is used to download resource files, stored in a 03-Tools / Repo directory, add the following operations this file to the user environment.
mkdir ~/bin
cp ~/03-Tools/Repo/repo ~/bin
chmod a+x ~/bin/repo
export PATH=~/bin:$PATH Configure git
Need to use git, follows the basic configuration when the resources to download, the user name and mailbox name change for the user name.
git config --global user.name "abc123"
git config --global user.email "[email protected]"
git config --list3. Android system to compile and burn
Android image compilation requires much time, it can be compiled to burn development board view mirror effect, using UUU burn burn. Here in this section we will first describe how the image burned into EMMC and SD card, and then describes the compiler mirroring.
3.1 Android mirroring method of burning EMMC
Compiled mirror located 02-Image catalog, the android_p9.0.0_2.0.0-ga_image_8mq-myd-MT53D512M32D2DS-053.zip into the WINDOWS system decompression.
UUU burning will create a soft link, so please open cmd with administrator privileges, as shown below:
Jump to extract the directory, execute
uuu_imx_android_flash.bat -f imx8mq -a -e -c 7
Next, make sure the development board is not inserted, such as TF TF card slot, a port TypeC end computer, the other end of the bottom plate tyepC port (J8), the DIP switch is set to (sw1) LLHL (sw2) HL, and power.
Burning process is as follows:
After programming, the DIP switch is set to (sw1) LLHL (sw2) LH to start.
3.2 Android mirroring burning SD method
compiled mirror located 02-Image catalog, the android_p9.0.0_2.0.0-ga_image_8mq-myd-MT53D512M32D2DS-053.zip into the WINDOWS system decompression. UUU burning will create a soft link, so please open cmd with administrator privileges, as shown below:
Jump to extract the directory, execute
uuu_imx_android_flash.bat -f imx8mq -a -e -c 7 -t sd
Next, make sure the development board is not inserted, such as TF TF card slot, a TypeC end computer, the other end of the bottom plate tyepC port (J8), the DIP switch is set to (sw1) HHLL (sw2) HL, and power.
Burning process is as follows:
After reaching 3/3 insert TF card, please note this time.
After programming, the DIP switch is set to (sw1) HHLL (sw2) LH to start.
3.3 Android mirroring compilation method
, please extract the source myir_android9.0.0_2.0.0.tar.gz, then you can begin to compile the implementation of source myir_build.sh
mkdir android_dir
tar -zxf myir_android9.0.0_2.0.0.tar.gz -C android_dir
cd android_dir
source myir_build.sh myir_build.sh in
snip
#build_bootloader
#build_kernel
#build_dtbo
make -j4 2>&1 | tee build-log.txtbuild_bootloader compiler
uboot build_kernel compiled
kernel build_dtbo file compiled dtbo
make -j4 2> 1 & | full compilation tee build-log.txt
