Hardware
Schematics and board designs can be found here
Designs were created with Eagle
A limited functionality freeware version of Eagle can be downloaded here
There is very limited information about the A13 processor. The only detailed data found is an A10 datasheet which has some errors in it apparently. As this is the best source of low level information it is linked here
Software
DEBIAN SD CARD IMAGES
The A13 board can boot from the SD card. There are some ready made SD card images that are suitable. Some of these images can be found in this wiki section.
Once a suitable SD card is imaged with these files, place it into the board then power the board on, it should boot.
All images will have been generated for a specific SD card size. To use these images you must use a SD card that is the specified size or larger.
When the image is downloaded the SD card will only have partitions set up for the originally specified size for the image. If a larger SD card was used you can access the extra memory by using resize2fs.
Download Method
These images can be downloaded using the methods below
Windows:
- Download Win32 Disk Imager
- Insert card
- Start program
- Select file
- Click "write"
Linux:
- dd to card
For example an image with the file name of "debian_2g.img" would be downloaded to the SD card connected to a linux machine using the following command
# dd if=debian_2g.img of=/dev/sdX
where X is the uSD card.
Debian image
Configuration
- 2g SD card image
- 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
Note: as this comes in a tar.bz2 file this is best imaged using linux
Debian with GUI (X)
Configuration
- 4g SD card image
- wpa-supplicant (change /etc/network/interfaces to enter your ssid/key)
- xfce4
- tightvncserver (starts on boot)
- various dev tools (python, gcc, etc)
- sudo
- 500mb swap file
- custom (non-debug) kernel
- default user name and password: olinuxino and olinuxino
once logged in to start the user interface type "startx"
Script files
Script file
The script.bin is a text file with very important configuration parameters like port GPIO assignments, DDR memory parameters, Video resolution etc, by changing these parameters in the script.bin you can configure your Linux without need to re-compile your kernel again and again this is smart way Allwinner provides for tweaking A13 Linux Kernel
fex
The fex tool will convert a script.bin file to a text file and back again.
This allows the easy modification of the settings that are in the script.bin file
Tools and script files
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 LCD800x480settings
Changing A13-OLinuxino settings 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 partition 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 LCD800x600 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

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
