emDebian and GPIO

JayKay
Hello guys!

I was wondering if the emDebian linux distro is supporting the GPIO on
mini2440 out of the box? I definitely need a OS in which I could control
the GPIO with a C developed app. Is emDebian and uBoot a good choice? Maybe
I should rather try Angstrom linux? Any suggestions?

Thank you in advance!

Hi,

GPIO is hardware so you must have a driver to use it. What do you want to
do with GIPO? Use 1 or 2 pins? Me I using emdebian, and GIPO connected to
user button, so I can use default mini2440 kernel driver.

Hi themadmax,

what I actually want to do is use few GPIO pins (can not tell how many yet)
from a program written in C. I want to install Emdebian, to get rid off
QTopia, default Linux and other soft preinstalled on the board. I want to
have a clean OS installation to add the needed components by myself later
and duplicate the installation on a SD Card.

In the prior stage of my project I used a miniATX board and LPT port to
communicate with my other board. Now I want to make the whole device
smaller and use GPIO, because of the lack of LPT.

Any help appreciated!

Thanks!
