GPIO in ARCHLINUX on Cubieboard a10

Question

I have installed archlinux on cubieboard A10, but i didnt find any /sys/class/gpio file in cubieboard.

I want to know, how i will access cubieboard GPIO pin and make LED blink

Answer 1

As a noobi I found it difficult to begin with arch Linux. I found cubian+ xfce4 is easy for programming with python + wiring-cb. You can follow this page for more information

To blink leds in python : http://www.cubieforums.com/index.php?topic=766.0 I am writing a python script to check cubieboard1’s pinpoints/ headers. please feel free to ask if you need it.

Ok, l am sorry about that. I thought he is a beginner like me. I really searched for answers for long time and could not find a clear one. So I gave an easy way. So the difficult path to an answer start like this.
Check your script.bin has enabled gpio and your kernel has built in sunxi gpio?

[1] In kernel it should be enabled: Kernel with SUN4I_GPIO_UGLY = y 
[2] Use bin2fex tool from sunxi-tools to check your script.bin usually in /boot.

./bin2fex /path/to/script.bin > script.fex 
nano script.fex

eg: the last paragraph of script.fex should contain

[gpio_para]
gpio_used = 1
gpio_num = 67
gpio_pin_1 = port:PG03<1><default><default><1>
gpio_pin_2 = port:PB19<1><default><default><1>
gpio_pin_3 = port:PB18<1><default><default><1>
~to
gpio_pin_66 = port:PB10<1><default><default><1>
gpio_pin_67 = port:PH07<1><default><default><1>
