步驟整理-華為海思Hikey970開發板的AOSP編譯燒寫

最近結合第三方廠家與官方提供的編譯文檔，實踐整理了Hikey970單板編譯與燒寫Google原生AOSP（Android Open Source Project）系統的步驟。

單板參數：6GB LPDDR4

64GB UFS

具體流程如下。

一、Bootloader

1、sudo apt-get install uuid-dev build-essential2、mkdir bootloader cd bootloader3、git clone https://github.com/96boards-hikey/tools-images-hikey970.git git clone https://github.com/96boards-hikey/OpenPlatformPkg.git -b hikey970_v1.0 git clone https://github.com/96boards-hikey/arm-trusted-firmware.git -b hikey970_v1.0 git clone https://github.com/96boards-hikey/l-loader.git -b hikey970_v1.0 git clone https://github.com/96boards-hikey/edk2.git -b hikey970_v1.0 git clone https://github.com/96boards-hikey/uefi-tools.git -b hikey970_v1.04、cd edk2 ln -sf ../OpenPlatformPkg5、vim ${BUILD_PATH}/l-loader/build_uefi.sh 具體改動見下圖6、 編譯 l-loader/build_uefi.sh hikey970

二、Kernel

1、mkdir kernel cd kernel2、git clone https://github.com/96boards-hikey/linux.git -b hikey970-v4.93、設置環境變數export ARCH=arm64export CROSS_COMPILE=/xxx/aarch64-linux-android-4.9/bin/aarch64-linux-android-（編譯鏈下載：git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9）4、make hikey970_defconfig make -j4 make hisilicon/kirin970-hikey970.dtb

三、AOSP

1、mkdir aosp cd aosp2、1）牆外用戶：repo init -u https://android.googlesource.com/platform/manifest -b master 2）牆內用戶：repo init -u git://mirrors.ustc.edu.cn/aosp/platform/manifest -b master （建議先離線下載壓縮包，而後到Linux環境下解壓）3、git clone https://github.com/96boards-hikey/android-manifest.git -b hikey970_v1.0 .repo/local_manifest4、sudo repo sync （最終大約100+G）5、編譯 Copy kirin970-hikey970.dtb (arch/arm64/boot/dts/hisilicon/ kirin970-hikey970.dtb) to the device/linaro/hikey-kernel directory as file: kirin970-hikey970.dtb-4.9 Copy the Image file (arch/arm64/boot/Image.gz-dtb) to the device/linaro/hikey-kernel directory as file: Image.gz-hikey970-4.9 source ./build/envsetup.sh lunch hikey970-userdebug make -j16

生成 boot.img：

1、Copy Image and kirin970-hikey970.dtb from kernel directory2、copy ramdisk.img from android out/3、cat Image kirin970-hikey970.dtb > Image-dtb mkbootimg --kernel Image-dtb --ramdisk ramdisk.img --cmdline "androidboot.hardware=hikey970 firmware_class.path=/system/etc/firmware loglevel=15 buildvariant=userdebug androidboot.selinux=permissive clk_ignore_unused=true initrd=0xBE19D000,0x16677F earlycon=pl011,0xfff32000,115200 console=ttyAMA6 androidboot.serialno=54DA9CD5022525E4 clk_ignore_unused=true" -o boot.img

四、燒寫

1、將單板上的撥碼開關撥到1、3 ON，2、4 OFF，即fastboot mode everytime模式

2、用Type-C線將單板上非串口調試的Type-C口與電腦USB口相連

3、在Windows CMD中使用fastboot工具燒寫各鏡像文件

fastboot flash ptable l-loader/ptable-aosp-64g.imgfastboot flash xloader tools-images-hikey970/sec_xloader.imgfastboot flash fastboot l-loader/l-loader.binfastboot flash fip l-loader/fip.binfastboot flash boot boot.imgfastboot flash cache cache.imgfastboot flash system system.imgfastboot flash userdata userdata.img

另，由於hikey970官方與第三方廠商均未提供官方QQ群以供開發者交流，在此特創建QQ群：609941175,希望Hikey970的開發者或者Android/Linux 各層開發者加入，大家一起交流學習，共同進步！
