Build AOSP for ROCK960
Build environment setup
Recommend build host is Ubuntu 16.04 64bit, for other hosts, refer official Android documents Establishing a Build Environment.
$ mkdir -p ~/bin
$ wget 'https://storage.googleapis.com/git-repo-downloads/repo' -P ~/bin
$ chmod +x ~/bin/repo
Android’s source code primarily consists of Java, C++, and XML files. To compile the source code, you’ll need to install OpenJDK 8, GNU C and C++ compilers, XML parsing libraries, ImageMagick, and several other related packages.
$ sudo apt-get update
$ sudo apt-get install openjdk-8-jdk android-tools-adb bc bison build-essential curl flex g++-multilib gcc-multilib gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc yasm zip zlib1g-dev
Configure the JAVA environment
$ export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
$ export PATH=$JAVA_HOME/bin:$PATH
$ export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
Download source code
$ mkdir rock960-android
$ cd rock960-android
Then run:
$ ~/bin/repo init -u https://github.com/96rocks/manifests.git -b rock960-box-7.1 -m rock960_box_7.1_release.xml
$ repo sync -j$(nproc) -c
It might take quite a bit of time to fetch the entire AOSP source code(around 86G)!
Build u-boot
$ cd u-boot
$ make rk3399_box_defconfig
$ ./mkv8.sh
$ cd ..
The generated images are rk3399_loader_v_xxx.bin and uboot.img
Building kernel
$ cd kernel
$ make rockchip_defconfig
$ make rk3399-rock960-model-ab.img -j$(nproc)
$ cd ..
The generated images are kernel.img and resource.img:
- kernel.img, kernel with rkcrc checksum
- resource.img, contains dtb and boot logo, Rockchip format resource package
Building AOSP
$ source build/envsetup.sh
$ lunch rk3399_box-userdebug
$ make -j$(nproc)
源码编译报错
ubuntu 18.04 和 android 8.1
flex-2.5.39: loadlocale.c:130: _nl_intern_locale_data: Assertioncnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.
Aborted (core dumped)解决
export LC_ALL=CLC_ALL=C 去除所有本地化的设置，或者LC_ALL=en_US.utf-8
It takes a long time, take a break and wait…
Generate images
$ ln -s RKTools/linux/Linux_Pack_Firmware/rockdev/ rockdev
$ ./mkimage.sh
The generated images under rockdev/Image-rk3399_box are
boot.img MiniLoaderAll.bin parameter.txt pcba_whole_misc.img resource.img trust.img
kernel.img misc.img pcba_small_misc.img recovery.img system.img uboot.img
They can be flashed with fastboot or Rockchip upgrade_tool.
Pack all partitions into one image.
$ cd rockdev
$ ln -s Image-rk3399_box Image
$ ./mkupdate.sh
Start to make update.img...
