Power on and System boot up
Once Matrix-518 is correctly power on, it will start boot Linux
kernel and mount file system. You can use Ethernet and telnet
and login Matrix-518. Once kernel loaded, it will find /sbin/
init and execute it. The initialization configuration is at /etc/
inittab. Once boot up, you can use telnet to login Matrix-518.
Default started service
1. amgrd (Artila broadcast search daemon)
2. ssh (secured shell) with sftp
3. syslog/klogd (system and kernel log)
4. telnet server (disable root with /etc/securetty)
5. ftp server (vsftp)
6. web server (apache2)
7. Ready LED (debug LED for internal use)
Network Settings
Use vi editing tool to edit the /etc/network/interfaces for network
setting. The default setting is static IP 192.168.2.127. Matrix-518
also supports Wireless LAN. Use
wireless_essid XXX
wireless_key YYY
To add SSID and WEP key if necessary. XXX is SSID and YYY
is WEP Key
Matrix-504 supports USB WLAN adaptor (Ralink RT2571).
You can enable the driver module (rt73usb) by adding rt73usb in
/etc/modules
File System
The 128MB NAND Flash memory of Matrix-518 contains Boot
loader (uBoot), Linux Kernel, Root File System and user disk
(\home). The file system and disk space are shown as follow
Inittab and Run levels:
Inittab contains information of system initialization. The
system initialization script /etc/rcS.d runs first then the run
level 5 /etc/rc5.d Matrix-518 uses run level for system setup
and the default run level is number 5. Please refer to
introduction to linux (http://tille.garrels.be/training/tldp/) for
information about run level. Following is the run levels
setting:
Run level 0: halt
Run level 1 is single user ( login and service are disabled )
Run level 2~5 are multiple users
Run level 6 is reboot.
Please refer to loader menu section for selection of run level
Insert kernel module
To insert kernel module while system boot up, please use vi to
edit /etc/modules to add module to load e.g.
rt73usb
To load the USB WLAN adaptor.

Getting started with the Hello program
There are many example programs in Artila CD. To compile the
sample you can use the Make file and type
make
To compile and link the library. Once done, use ftp command
ftp 192.168.2.127
Then login with password. Use bin command to set transfer
mode to binary
ftp>bin
to transfer the execution file to Matrix 504 user disk (/home/
guest) and use
chmod +x file.o
To change it to execution mode and
./file.o
to run the program
Auto start program on boot:
To start a program on boot, you can use /etc/rc.local
For example to use vi to edit rc.local
hello &
exit 0
Hello will be executed after system boot up. rc.local has the
similar function as /etc/rc in Matrix-504
Artila Utility Software:
The introduction of Artila utility software as follow:
1. update : update loader, environment file and kernel image.
Type update—help to find the command usage
Update can only operated under supervisor mode (password :
root). Please use command su and login as root
2. setuart: configure serial port setting. An example show as
followed to configure port 1 as RS-485 interface with baud rate
921600.
3. setconsole: Unlike Matrix-510 which shares the serial
console port with the serial port 3, Matrix-518 uses dedicated
pins for serial console (debug port). setconsole command
allows user to redirect the serial console port to any one of the
four serial port of M-518. Therefore user can avoid opening
the metal case to access the serial console.
3. version: find out the version of OS.
4. gpioctl: The gpio can be configured by gpioctl and the
usage is as shown followed.
5. audio command:
madplay - play mp3 file
aplay - play wav file
amixer - volume control
alsamixer - graph control
Loader Menu
Loader menu helps user to select the run level of system boot
up. User need to use serial console to enter loader menu.
Please configure the serial port of terminal as follow:
Baud Rate: 115200
Data bits: 8
Parity: N
Stop bit: 1
Flow Control: None
Terminal type: VT100
Once power up M-518, please repeatedly keying “@” and
you will see the loader menu appear as follow:
Frequently Asked Question
1. Forgot password:
If you forgot the password for login, please use serial console and
use run level 1 to boot system. Use passwd to change the password
setting.
2. Forgot the IP address
If you forgot the M-502 IP address, you can use the Java Manager
available in Artila CD to search the IP address of M-502
Or use serial console port to find out the IP address by
#ifconfig
If you miss the timing, please power on again the M-502 and
do it again. Select U will prompt the run level selection
message. Run level 0 is halt, run level 1 is single user
( disable login and service ). Run level 2~5 are multiple
users and run level 6 is reboot. To view the run level
configuration, please check
/etc/inittab
3. System fail to boot
If you mess up the root file system and make the system fail to boot,
M-502 will automatically switch to boot from Dataflash file system
and a console menu will show up at console port to help user
perform system recovery. System Recovery Section will tell you
how to recover the system.
System Recovery
If NAND Flash file system does fail, DataFlash file system
will automatically boot up and a Console Menu at console
port will appear as follow:
1. Update Image: this option can recover the loader, kernel
and file system by using an USB disk. The USB disk
contains the images files with the path as follow:
Loader: m518/m518.alf
Kernel: m518/m518K
File system: m518/m518R
The files are available in Artila CD. Please prepare an USB
disk and copy the image files to it before choosng this option.
Make user’s filesystem
2. Make Filesystem: this option is used to create customized
file system. Before using this function, you need to copy the
folder of mkimage504 in the Artila CD to an USB disk. This
function will create a new file system image for users and
they can use it to duplicate the customized file system to other
Matrix-518.
Recover Environment File
3. Recovery Env.: The option will recover the environment
files as default setting. Use this function only when the
NAND file system crash.
4. Show Info: Show the version information of Matix-518
5. Reboot: Reboot the NAND flash file system.
Update Image Starts
Update Image Completes
Make Files System Starts
Note:
1. Use Arrow keys up and down to selection the functions
2. Use Arrow keys left and right to go to higher or lower levels
of menu screen
Force DataFlash boot
1. To force system go into DataFlash booting, repeatedly
keying “!” (Shift +1 ) right after Matrix-518 power on.

ipkg software package management
Matrix-518 uses ipkg to manage the software installation, upgrade and
removal. Artila will continuously add the kernel module and utility at
our ftp server, user can install these software from Artila’s ftp server. In
addition user can also setup your ftp server to update the software you
want. To install the utility from Artila ftp, please use vi to edit the /etc/
ipkg.conf
src/gz arm ftp://ftp:ftp@ftp.artila.com/AT9G20/Artila-CD/Linux/Utility
src/gz kernel ftp://ftp:ftp@ftp.artila.com/AT9G20/Artila-CD/Linux/
modules
You can also copy the Utility and module folder from Artila CD to a
USB disk, then use USB disk to install the software by changing the
ipkg.conf
src/gz usb_arm ftp://root:root@127.0.0.1/media/sda1/Utility
src/gz usb_kernel ftp://root:root@127.0.0.1/media/sda1/modules
Make sure the USB disk is correctly mounted, now use command
ipkg update
to update the package list and use
ipkg install webmin
To install webmin. Webmin is a web-based interface to system
administration. To start webmin, go to /etc/webmin and type
start webmin
Then you can use browser to visit Matrix-518 port 10000
The webmin for Matrix-518 provides following modules:
1. Webmin: webmin configuration
2. System: system boot, process and log management
3. Server: Apache and SSH server configuration
4. Network: network configuration
5. Hardware: RTC setting
6. Others: File manager, upload and download
Remember to use command
