DEBIAN SD CARD IMAGE

A13 Debian Linux Image Debian SD card image on A13-OLinuXino board without X, includes: Mplayer CLI, GCC

The default user/password are root/password

Extract it and write the image (A13_Micro_Debian_first_preliminary_release.img) on SD card

A13 script bin and fex tool

The directory A13_script_files contains:

script.bin - the default script with VGA800x600settings

fex2bin_bin_fex_tools.tar.gz - tools fex2bin and bin2fex for converting the *.bin script file to *.fex(text file)

script_GPIO_VGA - script with VGA800x600settings

script_GPIO_LCD_800x480 - script with VGA800x480settings

Changing A13-OLinuxino setings to VGA800x600 or LCD800x480

The default SD card setup is made with settings for VGA 800x600. If you want to switch between VGA 800x600 and LCD800x480 mode then you have to replace the existing script.bin file from the first SD card partitition (note that this partitition is FAT - so you can replace the file under Windows or Linux) with the script.bin file from script_GPIO_VGA directory (if you want to change to VGA800x600 mode) or from script_GPIO_LCD_800x480 directory (if you want to change to VGA800x600 mode).

Establish WIFI connection

plug in MOD-WIFI-RTL8188 if the board is not A13-OLinuXino-WIFI

type ifconfig -a

lo Link encap:Local Loopback 

         inet addr:127.0.0.1  Mask:255.0.0.0

         RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

wlan2 Link encap:Ethernet HWaddr 48:02:2a:eb:21:1c 

         inet addr:192.168.0.229  Bcast:192.168.0.255  Mask:255.255.255.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

         collisions:0 txqueuelen:1000
         RX bytes:31361 (30.6 KiB)  TX bytes:1248 (1.2 KiB)

and look at your wlan number. In this case we have wlan2

open the file /etc/network/interfaces- for example using vi tool

vi /etc/network/interfaces

and change

auto wlan2

iface wlan2 inet dhcp

wpa-ssid YourSSIDname

wpa-psk YourWPAkey

reboot A13-OLinuXino board

Chek your connection

ifconfig -a

if everything is ok you should see something as:

wlan1 Link encap:Ethernet HWaddr 48:02:2a:eb:21:1c 

         inet addr:192.168.0.229  Bcast:192.168.0.255  Mask:255.255.255.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

         TX packets:7 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:31361 (30.6 KiB)  TX bytes:1248 (1.2 KiB)


Establish ethernet connection using USB-ETHERNET adapter

recommended supported adapter USB-ETHERNET-AX88772B

plug in USB-ETHERNET-AX88772B adapter

type

ifconfig -a

you should see something like this

eth1 Link encap:Ethernet HWaddr 00:80:80:9a:4a:63 

         inet addr:192.168.0.113  Bcast:192.168.0.255  Mask:255.255.255.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:58 errors:0 dropped:0 overruns:0 frame:0
         TX packets:4 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:7852 (7.6 KiB)  TX bytes:510 (510.0 B)

lo Link encap:Local Loopback 

         inet addr:127.0.0.1  Mask:255.0.0.0
         UP LOOPBACK RUNNING  MTU:16436  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

tunl0 Link encap:IPIP Tunnel HWaddr 

         NOARP  MTU:1480  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

look at your eth number. In this case we have eth1

open the file /etc/network/interfaces- for example using vi tool

vi /etc/network/interfaces

and change the following rows

auto eth1

iface eth1 inet dhcp

where eth1 is the interface number

reboot A13-OLinuXino board

or type ifup eth1

Check your connection

ifconfig -a

if everything is ok you should see something as:

eth1 Link encap:Ethernet HWaddr 00:80:80:9a:4a:63 

         inet addr:192.168.0.113  Bcast:192.168.0.255  Mask:255.255.255.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:725 errors:0 dropped:0 overruns:0 frame:0
         TX packets:10 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:77056 (75.2 KiB)  TX bytes:1686 (1.6 KiB)


GPIO

GPIO changing

type lsmod

if sun4i-gpio is present - OK

unless type modprobe sun4i-gpio

go to /sys/devices/virtual/misc/sun4i-gpio/pins and type ls

list of supported pins will be shown

example for port reading: cat pe4 read PortE4 the result should be 0 or 1 example for port writing: echo 1 > pg9 - turn on LED

Changing A13 GPIO direction

extract fex2bin_bin2fex_tools on linux machine

sudo su

enter password

cd fex2bin_bin2fex_tools directory


mount /dev/sdx1 /mnt/sd - mount first partitition on SD card

./bin2fex /mnt/sd/script.bin > /mnt/sd/script_test.fex - convert bin file to fex

gedit /mnt/sd/script_test.fex

GPIOs are defined in the end.

where

Pxx<mode><pull><drive> mode 0-7, 0=input, 1=ouput, 2-7 I/O function pull 0=none, 1=up, 2=down drive 0-3, I/O drive level data - data output - logical 0 or 1

for example: if you want to change GPIO direction then change first parameter after port name: gpio_pin_8 = port:PE08<0><default><default><default> make PE8 input gpio_pin_8 = port:PE08<1><default><default><default> make PE8 output

save and exit

./fex2bin /mnt/sd/script_test.fex > /mnt/sd/script.bin - convert fex to bin
