This archive includes all the files to fastboot image to emmc or write it to sdcard.Option 1 (Fastboot to eMMC):First you need to enter fastboot mode:From U-Boot prompt, enter the following command:

=> fastboot 0

Once the platform is in fastboot mode, you simply need to call the flashing script:

~/$ unzip p900-nitrogen8mm-*.zip -d p900-nitrogen8mm
~/$ cd p900-nitrogen8mm/device/boundary/scripts/
~/p900-nitrogen8mm/device/boundary/scripts$ sudo ./flash_fastboot.sh nitrogen8mm

Note that it is recommended to use a standard USB2.0 mini-USB cable for fastboot to work, it has been reported that U-Boot has some issues with USB3.0 OTG cable.Option 2 (Write to sdcard):Connect sdcard to the host pc and find out where it mounts at using "lsblk" command: (Assume it is mounted to /dev/sdX)Now use the mksdcard.sh script included in the zip file to write the Android to your sdcard using the following:

~/$ unzip p900-nitrogen8mm-*.zip -d p900-nitrogen8mm
~/$ cd p900-nitrogen8mm/device/boundary/scripts/
~/p900-nitrogen8mm/device/boundary/scripts$ sudo ./mksdcard.sh -b nitrogen8mm -d /dev/sdX

What's new?

This section will only describe the changes brought either by the OS update itself or modified/added features.

Android Pie OS updates

Google provides a list of notable changes for developers:

• https://www.android.com/versions/pie-9-0/

Linux Kernel 4.14.x

This Android Pie release is based on a 4.14.x kernel. It therefore benefits from all our latest drivers/fixes.Just like our other branches, we will include latest security updates to it.

• https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/

Source code access

For the newcomers, please make sure to read our "Android Getting Started Guide" since it contains all the information you need to download, build and flash an Android image.

• https://boundarydevices.com/android-getting-started-guide/

For those already familiar with our releases, here is a condensed version to get the Android Pie source code:

~/$ mkdir myandroid
~/$ cd myandroid
~/myandroid$ repo init -u git://github.com/boundarydevices/android-manifest.git \
       -b boundary-imx-p9.0.0_1.0.0-ga
~/myandroid$ repo sync

After that, you need to get NXP vendor package from here:

• https://www.nxp.com/webapp/sps/download/license.jsp?colCode=P9.0.0_1.0.0_GA_ANDROID_SOURCE&appType=file1&DOWNLOAD_ID=null&lang_cd=en

Then please extract it:

~/myandroid$ tar xvzf imx-p9.0.0_1.0.0-ga.tar.gz

and then do as the following:

~/myandroid$ cp -r imx-p9.0.0_1.0.0-ga/vendor/nxp/ vendor/
~/myandroid$ cp -r imx-p9.0.0_1.0.0-ga/EULA.txt .
~/myandroid$ cp -r imx-p9.0.0_1.0.0-ga/SCP* .

Then you can safely remove the nxp package sources using the following commands:

~/myandroid$ rm -rf imx-p9.0.0_1.0.0-ga/
~/myandroid$ rm imx-p9.0.0_1.0.0-ga.tar.gz

And finally you can build the android using the following commands:

~/myandroid$ source build/envsetup.sh
~/myandroid$ lunch nitrogen8mm-eng
~/myandroid$ make 2>&1 | tee build.out

As always, let us know your experiences (both good and bad) when you test out this image.
