A x86 based Linux system with installed cross-compile toolchain / SDK Android development is required for i.MX 8-based congatec designs. It is possible to use a virtual machine but a dedicated system is preferrable. Furthermore, the host should have a serial port to access the serial console and an SD card reader.

The i.MX 8-based congatec designs require a 64-bit Ubuntu 16.04 system as the host for Android development.

Setting up and building Android

1. Installation in Ubuntu 16.04 64 bit [Clean install]

2. Some packages are needed:

$ sudo apt-get update $ sudo apt-get install uuid uuid-dev zlib1g-dev liblz-dev liblzo2-2 liblzo2-dev lzop git-core curl u-boot-tools mtd-utils android-tools-fsutils openjdk-8-jdk device-tree-compiler gdisk m4 libz-dev $ sudo apt-get install openjdk-8-jdk

3. Config the local git:

$ git config --global user.email "youremail" $ git config --global user.name "Your name"

4. A SSH key must be generated

In order to fetch te software from the congatec git server, after login into git.congatec.com go to the link https://git.congatec.com/-/profile/keys and follow the instructions there to generate and link a key with the computer will fetch and build the Yocto BSP.

5. Download and unpack the Android NXP

Download the release package https://www.nxp.com/webapp/Download?colCode=P9.0.0_2.3.4_ANDROID_SOURCE&appType=license

$ cd ~ (or any other directory you like) $ tar xzvf imx-p9.0.0_2.3.4.tar.gz

6. Getting i.MX Android NXP

$ mkdir ~/bin $ curl <https://storage.googleapis.com/git-repo-downloads/repo> > ~/bin/repo $ chmod a+x ~/bin/repo $ export PATH=${PATH}:~/bin $ source ~/imx-p9.0.0_2.3.4/imx_android_setup.sh # By default, the imx_android_setup.sh script will create the source code build environment in the folder ~/android_build # ${MY_ANDROID} will be refered as the i.MX Android source code root directory in all i.MX Android release documentation. $ export MY_ANDROID=~/android_build

8. Build the images

One way to make up for the limited RAM is using a bigger swap. Google recommends at least 16GB of RAM/swap so it’s not uncommon to create a 16GB swap when working in VM, to do this please use the following commands.

$ sudo fallocate -l 16g /mnt/16GB.swap $ sudo chmod 600 /mnt/16GB.swap $ sudo mkswap /mnt/16GB.swap $ sudo swapon /mnt/16GB.swap

Set the environment and build the images

$ cd $MY_ANDROID $ source build/envsetup.sh $ lunch cgtsmx8-eng $ make

9. Transfer the images to the SD card (/dev/sdX check your device)

After building is complete, you can access the target files with the following command:

$ cd out/target/product/cgtsmx8/

9.1 Bootcontainer

In order to use the bootloader according the target variant follow the next steps to fetch boot containers, remove the boot headers generated by the build

$ sudo git clone git@git.congatec.com:imx8_android_early_access/imx8_boot_container_binary.git

Check the CPU silicon, and memory of the target module.

  • conga-SMX8-X 4GB B silicon

$ ln -s imx8_boot_container_binary/u-boot-imx8qxp-cgtsx8x-4GB.imx u-boot-imx8qxp-cgtsx8x.imx

  • conga-SMX8-X 2GB B silicon

$ ln -s imx8_boot_container_binary/u-boot-imx8qxp-cgtsx8x-2GB.imx u-boot-imx8qxp-cgtsx8x.imx

  • conga-QMX8-X 4GB B silicon

$ ln -s imx8_boot_container_binary/u-boot-imx8qxp-cgtqx8x-4GB.imx u-boot-imx8qxp-cgtqx8x.imx

  • conga-QMX8-X 2GB B silicon

$ ln -s imx8_boot_container_binary/u-boot-imx8qxp-cgtqx8x-2GB.imx u-boot-imx8qxp-cgtqx8x.imx

9.2 Tranfer the images to the SDcard

9.2.1. conga-SMX8-X Y
$ sudo ./fsl-sdcard-partition.sh -f imx8qxp-cgtsx8x -o 32 -c 7 /dev/sdX
9.2.2. conga-QMX8-X A
$ sudo ./fsl-sdcard-partition.sh -f imx8qxp-cgtqx8x -o 32 -c 7 /dev/sdX

10. Hardware configuration

Bootcontainer is programmed into the SDcard, therefore the module needs be configured as follows:

conga-SMX8-X Y

Select on conga-SEVA
M17 ON-ON
M18 OFF-OFF

conga-QMX8-X A

Select on-module switch
SW1 ON-ON-OFF-OFF
