== Introduction ==
The preliminary Android Demo filesystem image for CM-T3730 is based on Android 4.1.1 Jelly Bean. The CompuLab preliminary Android Demo package for CM-T3730 includes ready to run Demo Android filesystem image and Linux kernel based on 2.6.37 version.

== Preparation steps ==
* Obtain a Linux PC workstation.
* Get a USB Card reader and a micro SD Card. You can either use the micro SD card, supplied with the CM-T3730 Evaluation kit, that has already been pre-partitioned as described in the [[CM-T3x: U-Boot: Firmware_Overview#Default MMC.2FSD card mapping | Default MMC/SD Card mapping]] article, or create a new one.
* Plug the USB SD Card reader to your 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 preliminary 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.

== Booting 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 [[#Booting Android | Booting Android]] section.
* 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-android-demo/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-android-demo/images/u-boot.bin /media/boot/
cp /path/to/cm-t3730-android-demo/images/uImage /media/boot/
</pre>

== Booting 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 preliminary Android Demo root filesystem on to that partition:
<pre>
sudo tar -xpf /path/to/cm-t3730-android-demo/images/Android-Demo-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 install it in 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.
* 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=dhcp \
omap_vout.vid1_static_vrfb_alloc=y vram=8M omapfb.vram=0:8M omapdss.def_disp=dvi omapfb.mode=dvi:1024x768-16"
</pre>
* To boot preliminary 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>
