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 VGA (800x600 or 1024x768) or LCD (480x272 or 800x480 or 1024x600)
The default SD card setup is made with settings for VGA 800x600. If you want to switch between VGA 800x600 and other modes then you have to replace the existing script.bin file from the first SD card partition (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_xxx directory (with the desired VGA resolution mode) or from script_GPIO_LCD_xxx directory (with the desired LCD resolution mode).
The archive of scripts might be downloaded from here: all available screen resolution scripts A13
Note that these scripts are not contemptible with A13-OLinuXino-MICRO boards!
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
