Android 9, Myon II

Gitlab Access:

This is only a quick-reference on how to setup and build an Android image.
For details please view the Android and NXP i.MX8M documentation NXP_Android_Docs.
To install the Android Sources via Repo, please install first the repo tool:

$: mkdir ~/bin
$: curl https://storage.googleapis.com/git-repo-downloads/repo  > ~/bin/repo
$: chmod a+x ~/bin/repo
$: export PATH=${PATH}:~/bin

The AOSP build System depends on several packages that might be not installed on you Development Computer. Refer to NXPs Android_Users_Guide: Android_User's_Guide.pdf

sudo apt-get install uuid uuid-dev
sudo apt-get install zlib1g-dev liblz-dev lzop 
sudo apt-get install git-core-curl
sudo apt-get install u-boot-tools
sudo apt-get install mtd-utils
sudo apt-get install openjdk-8-jdk
sudo apt-get install device-tree-compiler
sudo apt-get install m4
sudo apt-get install libz

Clone the Repository Android-9 to a local Folder on your Ubuntu 18.04 Development Computer

git clone ssh://git@gitlab.keith-koep.com:30001/imx/android-9.git -b kuk_p9.0.0_2.2.0-ga 

or download und upack this Archive:
android9.0.0_2.2.0-kuk.tgz

Note: for the p9.0.0_2.3.0 preview take branch p9.0.0_2.3.0 or download und upack this Archive:
android-9.0.0_2.3.0-preview.tgz

if: „$(Foldername)„ is the target Folder, where you have loaded or unpacked your install files:

$ cd $(Foldername)
$ ./imx_android_setup.sh

This will create the source code build environment in „$(Foldername)/android-p9.0.0_2.2.0-ga-kuk“. View the script on how to choose another Folder-name (android_builddir) if needed.

Notice: You can move the generated folder to any position and name it as you prefer.

Notice2: You will need at least 75GB to unpack the sources.

Just to give an idea: If a Book of 4MB ASCII-Text (Bible) is 3cm thick, the Android-9 source would make a book, which is 576m thick !

Setup the build environment and choose configuration to use (i.e. $(AndroidFolder) is „$(Foldername)/android-p9.0.0_2.2.0-ga-kuk“):

$ cd ${AndroidFolder}
$ source build/envsetup.sh
# lunch <buildName-buildType>; i.e.:
$ lunch trizeps8mini-userdebug

Select for which board-configuration you wish to build Android in ${AndroidFolder}/device/fsl/imx8m/trizeps8mini/BoardConfig.mk:

# ###############################################################################################################################
# Select Target...
# TARGET_BOARD_NAME          := TR8MINI_IPANT7
# TARGET_BOARD_NAME          := TR8_PCONXS_EDT7
TARGET_BOARD_NAME          := MYON2_IPANM7
# TARGET_BOARD_NAME            := MYON2_CONXM
#
# ###############################################################################################################################

Execute the make command to generate the Image (i.e. for 16 build threads):

$ make -j16 2>&1 | tee build-log.txt

Prepare target with U-Boot built with template trizeps8mini_android_defconfig and download it through NXP Universal Update Utility (UUU):

~/uboot/uboot-imx$ make clean
~/uboot/uboot-imx$ make myon2_android_defconfig
~/uboot/uboot-imx$ make flash_mini

View U-Boot, Myon II for details.

Enter Bootloader Command Console and run fastboot command:

u-boot=> fastboot

Connect Target via USB to your development Computer and run:

$ ./KK-SCRIPTS/fastboot_imx_flashall.sh

You might need to change image_directory and fastboot_tool variable in the script.
