In order to improve the speed of compilation, VMWare Player 14.0 is installed on local hard
disk, and Ubuntu 18.04 LTS is installed on a SSD with at least 500GB size and USB3.1 specification.
When installing ubuntu 18.04 LTS to SSD, it should be allocated at least 350GB of disk space,
because compiling this version of android requires a larger disk space.
The following are detailed compilation steps:
Part l Configuring Ubuntu 18.04 LTS
1. Installing Ubuntu 18.04 on VMplayer 14.0
After installation is done, root user should be set at first.
# sudo passwd root
Then follow these steps to configuration ubuntu 18.04 for environment of compiliation
--Changing sources of ubuntu 18.04 mirror
If you are Chinese users, you can do the step, which can improve your system performance.
# sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
# sudo geit /etc/apt/source.list

| I.MX customers outside China do not need to modify Ubuntu source list, or can modify it to local mirror site of Ubuntu 18.04, which can improve the speed of software upgrade. |
Delet all sources and copy following lines here, Then save it and exit
| Changing ubuntu source |
|---|
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse |
Then running these 2 commands to update sources and packages
# sudo apt-get update
# sudo apt-get upgrade
2. Installing packages for compiliation

Part 2 Compiling Android Q10.0.0_2.1.0 BSP
1. Downloading NXP source code for Android Q10.0.0_2.1.0
File name is imx-android-10.0.0_2.1.0.tar.gz.
Copy the file to ~/, and decompress it.
# cd ~/
# tar zxvf ./imx-android-10.0.0_2.1.0.tar.gz
Then “imx-android-10.0.0_2.1.0” directory is created at ~/, now run the command to
download android source code.
# source ./imx-android-10.0.0_2.1.0/imx_android_setup.sh
| Comment |
|---|
| imx_android_setup.sh is a script file, which includes all steps needed by the environment of android Q10.0.0_2.1.0 BSP. If network environment is enough good, several hours later, it will be done. |
2. Compiling Android Q10.0.0_2.1.0
Referring to steps in Android_User's_Guide.pdf, We summaries steps for compilation here:
(1) Preparing cross-compile tool chain
In Android_User's_Guide.pdf, 2 kinds of tool chain are recommended for users.
--- gcc-arm-8.3-2019.03-x86_64-aarch64-elf.tar.xz
--- gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz
Users can select one of them, and then decompress it to /opt/ directory.
On how to download them or more details, see Android_User's_Guide.pdf, page 3.
Here we will use gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz as tool chain.
(2) Beginning to Compile Android Q10.0.0_2.1.0 BSP
Since this version of Android BSP requires high memory capacity when compiling, if the
memory configuration of the virtual machine is incorrect, it is very likely to cause the compilation
to fail. The following is a list of variable tests for user reference:
# cd android_build
# export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-
# source build/envsetup.sh
# lunch evk_8mp-userdebug
# ./imx-make.sh -j2 2>&1 | tee build-log.txt
Part 3 Errors During Compilation
1. Allocating 8GB Memory For VMware Player
# ./imx-make.sh -j1 2>&1 | tee build-log.txt
2. Allocating 12GB Memory For VMware Player
# ./imx-make.sh -j4 2>&1 | tee build-log.txt
# ./imx-make.sh -j4 2>&1 | tee build-log.txt (Run it again)
# ./imx-make.sh -j4 2>&1 | tee build-log.txt (Run it again)
So if we use 4 thread to compile BSP, command for compilation will have to be run for 3 times.
