I am a new user to beaglebone and I have a couple of basic questions. I want to know what is meant by DT or Device tree overlay and why it is required for BB/ ARM335X. Is it not required for other main processors like Intel because they are " defined" in the Linux kernel? and TI ARM3358 processor is not " defined" . What support is available for other "popular" processors and is not available for TI ARM 3358 in Linux Kernal? Or was there support BEFORE and was it taken BACK? I mean is this the reason that we make a device tree and pass it to the system ? I may have mentioned incorrect statements please feel free to correct me.
secondly, I know that with no Device tree stuff, it is possible to lighten up an LED connected to the BB and BBB using the terminal. So if the definitions are not there in the Linux kernel, how come this method works? I mean how can one export a GPIO and lighten the LED connected if that is not found in the kernel? If so, then is a DT necessary at all? A confused. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
