== Overview ==
The example run-time Linux filesystem image for the CompuLab CL-SOM-AM57x System-on-Module / Computer-on-Module is based on Debian 8.2 GNU/Linux Jessie (armhf).

The default Debian Jessie Linux image includes more than 400 software packages. Among them:

* Core system
* Debian package management system
* X11 Windowing System
* Fluxbox desktop manager
* Netsurf browser
* Apache web server
* Samba connectivity suite
* SSH server and client
* ALSA configuration and usage utilities
* Bluetooth tools and daemons

The [[CL-SOM-AM57x: Linux: Getting started|Getting started]] page provides a brief introduction on how to install the run-time Linux image.

== Using Debian Linux on CL-SOM-AM57x ==

=== Connection and Logging In ===
Use the following username and password to login:

Account with administrative privileges:
<pre>
cl-debian-armhf login: root
Password: 111111
</pre>

Regular user account:
<pre>
cl-debian-armhf login: user
Password: 111111
</pre>

To login into the Linux system, you may use a serial console (ttyO2) at 115200 bps, or connect through the network, or use a keyboard and HDMI display.

=== X Windows system ===
CompuLab DEMO root filesystem image contains fully featured X server system with Fluxbox window manager.
Before starting X server, connect USB mouse and keyboard to the system.
You can run X server and Fluxbox window manager by typing {{cmd|startx}}.

=== Fluxbox window manager ===

CL-SOM-AM57x Debian Linux features installed Fluxbox package - a lightweight window manager for the X server system.

* Fluxbox provides configurable window decorations, a root menu to launch applications and a toolbar that shows the current workspace name, a set of application names and the current time. There is also a workspace menu which allows you to add or remove workspaces. The {{parameter|slit}} can be used to dock small applications, e.g. most of the bbtools can use slit.
* Fluxbox can iconify windows to the toolbar, in addition to adding the window to the Icons submenu of the workspace menu.

Visit [http://fluxbox-wiki.org Fluxbox Wiki] and [http://fluxbox.org/ Official home page] for more details.

=== Software Management ===

Debian Linux image for CL-SOM-AM57x includes all the information required to use Debian package management utilities.
You can use [http://linux.die.net/man/8/apt-get apt-get] and [http://www.wlug.org.nz/dpkg(8) dpkg] out of the box.

=== Display options ===
CL-SOM-AM57x evaluation platform has four video output interfaces: HDMI, LCD, DVI, and LVDS.
Default configuration of Debian Linux for CL-SOM-AM57x uses HDMI (SB-SOM-AM57x J4 connector) as primary video output.

=== MMC/SD ===
The support for MMC/SD card on CL-SOM-AM57x is built into the Linux kernel.
To mount the memory card, monitor {{filename|/proc/partitions}} to see what partitions were detected on the MMC/SD card.
For example, suppose MMC/SD partition you'd like to mount is {{filename|mmcblk0p1}} then:
<pre>
mkdir -p /mnt/mmcblk0p1 && mount /dev/mmcblk0p1 /mnt/mmcblk0p1
</pre>

=== USB 3.0 Dual-Role-Device ===

CL-SOM-AM57x has USB DWC3 (XHCI) based controller.
It features SuperSpeed (SS) USB 3.0 Dual-Role-Device (DRD) subsystem with integrated SS (USB3.0) PHY and HS/FS (USB2.0) PHY.
Current Linux kernel support of DWC3 features does not allow dynamic role (host/device) switching in runtime.
By default, {{parameter|host}} role is assigned to CL-SOM-AM57x USB 3.0 port.

=== RTC ===
To access the RTC time and date run:
<pre>
root@cm-debian:~# hwclock
Sat Jan 1 00:00:00 2000 -10.011159 seconds
</pre>

To set the date and write it into the RTC do the following:
<pre>
root@cm-debian:~# date -s "31 JUL 2015 10:00:00"
Fri Jul 31 10:00:00 UTC 2015
root@cm-debian:~# hwclock -w
root@cm-debian:~# hwclock
Fri Jul 31 10:00:13 2015 -1.066224 seconds
</pre>
