Hope my problem is close to the ogirin topic of the post, and there are many developers who would find useful the problem solution I need. I have always used micros in bare metal fashion and have always had direct control to drive GPIO ports however I wanted. Having a problem logging in? They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. I understand, that the post topic is old and nobody might not look at my posting, byt yet nonetheless The process with Linux shell is the following:

The time now is I’ve you find something let me know: Has anyone some sample code for a similar board or can help me to access the keys and leds? I would be interested in seeing some application implementation examples as well. I guess a question can’t get any more basic than this one. Find More Fpio by rk1genius.

BB code is On. Before Asking I’ve reviewed these documents: How bpio i find or where is this table definig the banks? Hi, With Linux versions v3.

Rain dance time, IH. Discussions involving Arduino, plug computers and other micro-controller like devices are also welcome.

Ok got it working with the open, and write functions. Are you new to LinuxQuestions. The Device Tree is for configuring the board, and are used by the device drivers in the kernel.

Is there a low level command in Linux that can access already known ports that will allow me to drive this port or a way to accomplish this without adding a new device with it’s own Linux driver? I eventually will need to drive some GPIOs high or low depending on a condition very slow binary status vpio.


Or is that really the only way to drive a darn GPIO port high and low? I would kindly appreciate any help in the issue. Regards, Evgenii Prun, Moscow, Russia. Glad I am not the only one trying to figure gppio out. I should have titled the subject, “The most basic Linux questions in the world” to get the most eyes.
