== Introduction ==
The Android Demo filesystem image for CM-T335 is based on [http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_JB_4_1_2_DevKit_4_0_1/index_FDS.html Android Jelly Bean 4.1.2] distribution for TI's Sitara(TM) AM335x ARM Cortex(TM) A8 Processors.
The [http://compulab.co.il/products/computer-on-modules/cm-t335/#devres CompuLab Android Demo package for CM-T335] includes ready to run Demo Android filesystem image and [[CM-T335: Android: Kernel|Linux kernel]] based on 3.2.0 version.

The Android Demo image for CM-T335 includes following software components:
* Android Jelly Bean 4.1.2 release from Google
* Android Linux Kernel v3.2.0
* SGX OpenGL ES Driver & Libraries DDK v1.10
* Built-in Applications and Demos
** Browser, Calculator, Clock, Contacts, Music, Search, File Manager, etc.
* Peripherals drivers
** MMC/SD, UART, Ethernet, etc.
** USB OTG and USB Host

The [[CM-T335: Android: Getting started|Getting started with Android on CM-T335]] page provides a brief introduction on how to install and boot the Android Demo image.
This article describes package structure and peripheral device options specific to the CM-T335.

= Package contents =

== version.txt ==
The contents of the {{filename|version.txt}} identifies the package version.

== images ==
* {{filename|uImage-cm-t335}} - ready to run Linux kernel image binary for CM-T335
* {{filename|Android-image-cm-t335.tar.bz2}} - Android root file system image archive

== development ==
The {{filename|development}} directory contains a collection of patches with support for CM-T335.
The directory structure preserves the original TI Android JB 4.1.2 source tree structure.
It contains patches for several Android sub-projects including Linux kernel.
* {{filename|build}} - contains a collection of patches that determine build specification for CM-T335
* {{filename|device/compulab/cm_t335}} - contains a collection of patches that introduce CM-T335 support
* {{filename|hardware/ti/omap3}} - patches for CM-T335 audio
* {{filename|kernel}} - contains a collection of patches for Linux kernel with support for CM-T335 peripherals

== kernel ==
* {{filename|uImage-3.2.0-cm-t335-1.bin}} - ready to run Linux kernel 3.2.0-cm-t335-1 for CM-T335 can be used with either Android or Linux root filesystem
* {{filename|linux-3.2.0-cm-t335-1.config}} - Linux kernel 3.2.0-cm-t335-1 configuration file
* {{filename|linux-3.2.0-cm-t335-1.patch}} - patch vs. [http://gitorious.org/rowboat/kernel/commit/996686459db1181a5deaf5d493681ecb5bf43ad7 rowboat-jb-am335x-4.1.2] tag with support for CM-T335 peripherals
* {{filename|patches}} - ordered collection of patches, that form the single patch above ({{filename|linux-3.2.0-cm-t335-1.patch}})

== utilities ==
The {{filename|utilities}} directory contains miscellaneous utilities useful for development
* {{filename|adb}} - prebuilt {{filename|adb}} binary for Linux host
* {{filename|busybox}} - prebuilt {{filename|busybox}} binary v1.19.4
* {{filename|eeprom-util}} - CompuLab EEPROM utility for reading information found inside the EEPROM on CompuLab boards

= Using Android on CM-T335 =
== USB Gadget ==
=== Introduction ===
There are two options for USB configuration available for the CM-T335:
* with single USB OTG port (U1 option)
* with four USB host ports (U4 option)
The CM-T335 Android Demo image supports both USB host and USB device ports in single binary image. USB host can be used to connect Keyboard/Mouse, Mass storage device, etc.
The USB device port is used for connecting to a PC workstation.

=== Android USB Gadget Configuration ===
The Android USB gadget driver is configured via the {{filename|sysfs}} entries.
The sysfs settings depend on the features required to be enabled.
By default only the adb and mtp mode is configured.
The adb mode is configured by default.
Please refer to the {{filename|device/compulab/cm_t335/init.cm-t335.rc}} for more details.

==== Android Mass Storage USB Gadgets ====
To enable Android Mass Storage USB Gadgets follow the instruction below:

* Set the Android Gadget to the Mass Storage mode:
<pre>
root@android:/ # echo 0 > /sys/class/android_usb/android0/enable
root@android:/ # echo mass_storage > /sys/class/android_usb/android0/functions
root@android:/ # echo 1 > /sys/class/android_usb/android0/enable
</pre>

* Make sure the external storage device you want to use (SD/MMC card partition) is plugged/installed into the CM-T335 and has a proper partition:
<pre>
root@android:/ # ls -l /dev/block/
...
brw------- root root 179, 0 2010-11-01 22:08 mmcblk0
brw------- root root 179, 1 2010-11-01 22:08 mmcblk0p1
brw------- root root 179, 2 2010-11-01 22:08 mmcblk0p2
...
root@android:/ # cat /proc/partitions
major minor #blocks name

31 0 2048 mtdblock0
31 1 1024 mtdblock1
31 2 1024 mtdblock2
31 3 1024 mtdblock3
31 4 4096 mtdblock4
31 5 6144 mtdblock5
31 6 508928 mtdblock6
179 0 7830528 mmcblk0
179 1 120456 mmcblk0p1
179 2 7709048 mmcblk0p2
</pre>

* Make sure the partition you're going to share is not mounted. Otherwise unmount it.

* Share the partition:
<pre>
root@android:/ # echo /dev/block/mmcblk0p1 > /sys/class/android_usb/f_mass_storage/lun/file
</pre>

* Finally, connect the CM-T335 to your host via USB OTG port.

==== ADB over USB ====
Please refer to the [[Android: ADB setup]] article for more information about the ADB over USB.
