=== Android porting on Dacu /Lizard ===
Android relies on the Linux kernel version 2.6.x, so, like many other linux systems, booting it is straightforward once a working Linux kernel image and a pre-built root file system are available. A big help in getting these software components come from the Texas Instruments Android Development Kit for Sitara Devices (http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/index_FDS.html), which provides, among other things, the Linux kernel source code and a Android 2.3.4 "Gingerbread" pre-packaged root file system source code.
The porting on Dacu /Lizard consisted in:
* patching the TI Android kernel source tree with the Dacucarrier board/Lizard SOM modifications
* adding kernel support for the capacitive touchscreen controller and buttons
* rebuilding the root file system, adding some demo and benchmark applications

=== Running Android: videos === Please watch the following videos: [http://www.youtube.com/watch?v=VhvlZL46R5Q Android Multitouch demo on Dacu/Lizard] [http://www.youtube.com/watch?v=RKkFoX3nEZw Running "Hello, world!" app on DACU/Lizard] === Booting Android === ==== Default IP address ==== {{ImportantMessage|text='''The default IP address is 192.168.0.122'''}} ==== From internal flash : standard operation ====
The Dacu system is provided with a pre-programmed Android environment. When started (please refer to [[Dacu#Quick_start | Dacu Quick Start]]), the bootloader loads the Android kernel and mounts the default root file system retrieving these components from the flash. For further information on the boot process, please refer to [http://elinux.org/Android_Booting Android Booting].
==== From the network : full control on boot process ====
In some cases (in particular during the development phase) it's required to boot the system loading different kernel images or root file systems. You can do this by setting up Dacu to load the kernel and root file sustem from the network, using tftp and nfs protocols. Please refer to [[Setting_up_tftp_and_nfs]] for instruction on how to install a tftp and nfs servers on the host environment. When the TFTP and NFS services are properly configured, copy the kernel image to the tftp directory (es: /tftpboot/dacu/android/uImage) and export via NFS the directory where the root file system archive has been previously uncompressed.
Once [[:Category:U-Boot|U-Boot]] is configured, you can launch the following command:
<preclass="board-terminal">
run net_andr_nfs
</pre>
The console should report the following boot messages:
<pre class="board-terminal">=> run net_andr_nfs Using DaVinci EMAC device TFTP from server 192.168.0.23; our IP address is 192.168.0.122 Filename 'lizard/dacu/uImage-android-cap-gpio'.
