一、依赖资源包

1、下载arm-none-eabi安装包：

https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

此处以gcc-arm-none-eabi-7-2018-q2-update-linux.tar.bz2为例。

注意：需下载Linux版本

2、下载NXP官方源码及环境配置包资源

https://www.nxp.com.cn/design/software/embedded-software/i-mx-software/android-os-for-i-mx-applications-processors:IMXANDROID?tab=Design_Tools_Tab

此处以imx-p9.0.0_2.1.1-auto-ga.tar.gz为例。

3、下载NXP官方文档

https://www.nxp.com.cn/design/software/embedded-software/i-mx-software/android-os-for-i-mx-applications-processors:IMXANDROID?tab=Documentation_Tab

此处以android_p9.0.0_2.1.1-auto-ga_doc.zip为例。

二、安装环境配置

1、环境变量设置：

export MY_ANDROID=/home/danny/i8QM/imx-p9.0.0_2.1.1-auto-ga/android_build export ARMGCC_DIR=/opt/gcc-arm-none-eabi-7-2018-q2-update export ARCH=arm64 export CROSS_COMPILE=$MY_ANDROID/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-android-

注意：

ARMGCC_DIR为编译M4核时需要的编译器。cmake 需要升级到3.13.0版本以上。

三、编译

1、编译Android image:

$ cd $MY_ANDROID $ source build/envsetup.sh $ lunch mek_8q_car-eng $ make 2>&1 | tee build-log.txt

2、编译UBOOT

$ cd ${MY_ANDROID} $ source build/envsetup $ lunch mek_8q_car-user $ make bootloader -j4

3、编译BOOT image

$ cd ${MY_ANDROID} $ source build/envsetup.sh $ lunch mek_8q_car-userdebug $ make bootimage -j4

4、编译Kernel

$ cd ${MY_ANDROID}/vendor/nxp-opensource/kernel_imx $ make android_car_defconfig $ make KCFLAGS=-mno-android

5、编译OTA

$ make otapackage -j4

6、编译DTB image

$ cd ${MY_ANDROID} $ source build/envsetup.sh $ lunch mek_8q_car-userdebug $ make dtboimage -j4
