== Introduction ==

The example run-time Linux filesystem image for CM-T3730 is based on Angstrom Linux 2009. The [http://www.compulab.co.il/t3730/download/t3730-linux.zip CompuLab Linux package for CM-T3730] includes ready to run Angstrom Linux filesystem image and Linux kernel configuration and source code patches.

The default Angstrom Linux image includes more than 1000 software packages. Among them:
* Core system
* X11 Windowing System
* Enlightment E17 desktop manager
* Firefox and Midory web browsers
* Office applications
* GIMP
* Totem, MPlayer and omapfbplay media players

The [[CM-T3730: Linux: Getting started|Getting started with Linux on CM-T3730]] page provides a brief introduction on how to install the run-time Linux image. This article describes package structure and peripheral device options specific to the CM-T3730.

== Using Angstrom Linux on CM-T3730 ==
=== Display options ===
CM-T3730 evaluation platform has four video output interfaces: LCD, DVI, LVDS and TV-out. Default configuration of Angstrom Linux for CM-T3730 uses DVI as primary video output. It is possible to switch between the DVI and LCD interfaces on the fly. TV-out can be used simultaneously with LCD or DVI interface.<br>
Linux implementation of the OMAP3 display subsystem is described in detail in {{filename|[http://gitorious.org/linux-omap-dss2/linux/blobs/master/Documentation/arm/OMAP/DSS Documentation/arm/OMAP/DSS]}} file in the Linux kernel source tree.

==== Display resolutions ====
* The Toppoly LCD supplied with CM-T3730 evaluation kit supports 480x640 resolution with 18 bits per color
* DVI output can be configured for standard resolutions using kernel command line parameter {{parameter|omapfb.mode}}:
*: 1024x768 - omapfb.mode=dvi:1024x768-24@60
*: 800x600 - omapfb.mode=dvi:800x600-24@60
*: 640x480 - omapfb.mode=dvi:640x480-24@60
* TV-out supports PAL and NTSC standards

==== Examples ====
===== Switch from LCD to DVI =====
<pre>
mgr0=/sys/devices/platform/omapdss/manager0
lcd=/sys/devices/platform/omapdss/display0
dvi=/sys/devices/platform/omapdss/display1
fb0=/sys/class/graphics/fb0

w=`cat $dvi/timings | cut -d "," -f 2 | cut -d "/" -f 1`
h=`cat $dvi/timings | cut -d "," -f 3 | cut -d "/" -f 1`

echo "0" > $lcd/enabled
echo "" > $mgr0/display
fbset -fb /dev/fb0 -xres $w -yres $h -vxres $w -vyres $h
# at this point you have to switch the dvi/lcd dip-switch from the omap board
echo "dvi" > $mgr0/display
echo "1" > $dvi/enabled
</pre>

===== Clone GFX overlay to LCD and TV =====
<pre>
ovl0=/sys/devices/platform/omapdss/overlay0
ovl1=/sys/devices/platform/omapdss/overlay1
tv=/sys/devices/platform/omapdss/display2
fb0=/sys/class/graphics/fb0
fb1=/sys/class/graphics/fb1

w=`cat $tv/timings | cut -d "," -f 2 | cut -d "/" -f 1`
h=`cat $tv/timings | cut -d "," -f 3 | cut -d "/" -f 1`

echo "0" > $ovl0/enabled
echo "0" > $ovl1/enabled

echo "" > $fb1/overlays
echo "0,1" > $fb0/overlays

echo "$w,$h" > $ovl1/output_size
echo "tv" > $ovl1/manager

echo "1" > $ovl0/enabled
echo "1" > $ovl1/enabled

echo "1" > $tv/enabled
</pre>

===== Switch TV-out from PAL to NTSC =====
<pre>
tv=/sys/devices/platform/omapdss/display2
echo "0" $tv/enabled
echo "ntsc" $tv/timings
echo "1" $tv/enabled
</pre>

=== GPIO access ===
Linux provides simple and convenient GPIO access via {{filename|sysfs}} interface. A GPIO should be exported using {{filename|/sys/class/gpio/export}}. After the GPIO is exported it is possible to change its direction and value using {{filename|/sys/class/gpio/gpioX/direction}} and {{filename|/sys/class/gpio/gpioX/value}} attributes.

==== Example ====
The following example demonstrates how to configure GPIO 140 as output and produce a 1usec pulse:

<pre>
echo 140 > /sys/class/gpio/export
echo 1 > /sys/class/gpio/gpio140/direction
echo 0 > /sys/class/gpio/gpio140/value
echo 1 > /sys/class/gpio/gpio140/value
usleep 1
echo 0 > /sys/class/gpio/gpio140/value
</pre>

=== Angstrom Linux package management ===
Angstrom Linux for CM-T3730 includes {{cmd|opkg}} package manager. It can be run either from command line, or using GUI. Go to "Settings" -> "Package Manager" to start the application, select packages you'd like to install and press "Apply" button.
