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
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 mode or to LCD800x480 mode:
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

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

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

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

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
Software
Linux Sunxi to build latest Kernel yourself
U-boot to build community U-boot

Andoroid 4.0.3 NAND flash prebuild image for LCD 800x480 resolution
LiveSuit for loading images to the NAND flash; to activate A13 bootloader do as follows: run Livesuit, disconnect the power supply and USB cable, then press HOME button, apply power supply, attach USB cable and release the button, Livesuit will detect the bootloader and will ask which file to program to the NAND flash.
