= Introduction =
The Android Demo filesystem image for CM-T3730 is based on Android 4.1.2 Jelly Bean with SGX (3D graphics acceleration) support. The CompuLab Android Demo package for CM-T3730 includes ready to run Demo Android filesystem image and Linux kernel based on 2.6.37 version.
{{Note|We do not recommend using Android Demo Image on CM-T3730 devices with less then 256MB of RAM.}}

= Preparation steps =
* Obtain a Linux PC workstation.
* Get a USB Card reader and a micro SD Card. Use either the micro SD card, supplied with the CM-T3730 Evaluation kit, or create a new one.
* Plug the USB SD Card reader to a host Linux PC. Insert the micro SD Card into the USB Card reader. From now we assume the device name of the MMC/SD card on your Linux PC is {{filename|/dev/sdc}}.
* Download the [http://compulab.co.il/products/computer-on-modules/cm-t3730/#devres Android Demo package for CM-T3730] from CompuLab website. Unzip the package to a directory on your host workstation.
* All image files mentioned below can be found in {{filename|images}} subdirectory of the Demo package.

= Intalling X-Loader and U-Boot =
* Create two partitions (FAT32 partition for X-Loader, U-Boot and Linux kernel and ext4 partition for root filesystem) as described in the [[CM-T3x: U-Boot: Firmware_Overview#Default MMC.2FSD card mapping | Default MMC/SD Card mapping]] article:
<pre>
Disk /dev/sdc: 8035 MB, 8035237888 bytes
32 heads, 32 sectors/track, 15326 cylinders, total 15693824 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x710ab397

Device Boot Start End Blocks Id System
/dev/sdc1 * 2048 242959 120456 c W95 FAT32 (LBA)
/dev/sdc2 243712 15693823 7725056 83 Linux
</pre>
* If you use the micro SD card, supplied with the CM-T3730 Evaluation kit, that has already been pre-partitioned as required, proceed to the [[#Installing Android | Installing Android]] section.
* Otherwise, download the [http://compulab.co.il/products/computer-on-modules/cm-t3730/#devres U-Boot package for CM-T3730] from CompuLab website. Unzip the package to a directory on your host workstation.
* Format for FAT32 partition:
<pre>
sudo mkfs.vfat -F 32 -n boot /dev/sdc1
</pre>
* Mount the partition under {{filename|/media/boot}} location:
<pre>
sudo mkdir -p /media/boot
sudo mount /dev/sdc1 /media/boot
</pre>
* Copy the X-Loader binary on to the boot partition and rename it as {{filename|MLO}}. It is essential that the {{filename|MLO}} will be the first file created on the MMC/SD card.
<pre>
cp /path/to/cm-t3730-u-boot/images/x-loader.bin /media/boot/MLO
</pre>
* Copy U-Boot and Linux kernel images on to the boot partition:
<pre>
cp /path/to/cm-t3730-u-boot/images/u-boot.bin /media/boot/
cp /path/to/cm-t3730-android-demo/images/uImage-cm-t3730.bin /media/boot/uImage
</pre>

= Installing Android =
* Format ext4 partition:
<pre>
sudo mkfs.ext4 -L rootfs /dev/sdc2
</pre>
* Mount the partition under {{filename|/media/boot}} location:
<pre>
sudo mkdir -p /media/rootfs
sudo mount /dev/sdc2 /media/rootfs
</pre>
* Extract the Android Demo root filesystem on to that partition:
<pre>
sudo tar -xpf /path/to/cm-t3730-android/images/Android-image-cm-t3730.tar.bz2 -C /media/rootfs && sync
</pre>
* Unmount all micro SD card partitions:
<pre>
sudo umount /dev/sdc1; sudo umount /dev/sdc2
</pre>
* Remove the micro SD card from the SD card reader and insert into the CM-T3730 micro SD card socket (P5).
* Continue to the [[#After Installation | After Installation]] section.

= After Installation =
* Connect the host PC to the SB-T35 base-board (connector P12) via the serial cable supplied with the evaluation kit.
* Start terminal emulation software on your PC. Set baud rate to 115200 bps, 8 bit per frame, 1 stop bit, no parity, no flow control.
* Connect the DataImage SCF0403 LCD display to the CM-T3730 evaluation system. The CM-T3730 Android Demo image is optimized to work with this display.
* Turn on the CM-T3730 evaluation system. The U-Boot boot-loader will start and you will get a command prompt.
* Set the {{parameter|bootargs}} environment variable:
<pre>
setenv bootargs "console=ttyO2,115200n8 androidboot.console=ttyO2 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait init=/init ip=off \
omap_vout.vid1_static_vrfb_alloc=y vram=8M omapfb.vram=0:8M omapdss.def_disp=lcd omapfb.mode=dvi:1024x768-16 cm_t3x_lcd=dataimage"
</pre>
* To boot Android Demo image type:
<pre>
CM-T3x # setenv bootdelay 3
CM-T3x # setenv bootcmd "mmc rescan; fatload mmc 0 82000000 uImage; bootm"
CM-T3x # saveenv
CM-T3x # boot
</pre>
