Hi Guys, I'm a complete linux beginner and currently have the following board that I am playing around with...

http://www.glomationinc.com/product_9260.html

the main chip onboard is an atmel arm9 core with a debian style distribution pre-installed. I have just updated the factory kernel to 2.6.30 as I was told this had an inbuilt GPIO driver? I am trying to interface the output pins on the header of the GESBC-9260 to the linux distribution. i.e. I would initially like to write a c file that did something like toggle an output pin, which I can then connect upto an led and see this flash. However I don't really have a clue where to start. Hopefully someone could point me in the right direction?

Judging by the sample code on the manufacturer's website, they are just writing directly to the ports, and not using the kernel at all.

However, if you want to use the gpio_sysfs driver, the avrfreaks wiki has a good description.
