Created page with "==Script files== '''Script file''' The script.bin is a text file with very important configuration parameters like port GPIO assignments, DDR memory parameters, Video resolut..."

New page

==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'''

[https://docs.google.com/open?id=0B-bAEPML8fwlNElERXRUZURTTUU 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 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 [https://www.olimex.com/Products/Modules/RF/MOD-WIFI-RTL8188/ MOD-WIFI-RTL8188] if the board is not A13-OLinuXino-WIFI

type
ifconfig -a

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

== Establish ethernet connection using USB-ETHERNET adapter ==

[https://www.olimex.com/Products/OLinuXino/A13/USB-ETHERNET-AX88772B/ 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><data>
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
