Hi,
I'm working with am335x (BeagleBone Black has it), which has Linux Kernel OS on it.
part of configuring its GPIOs involves writing a device tree which sets the Mode of the PINs to 'GPIO' mode.
I googled device tree in ARM processors for a decent tutorial, also watched this Tutorial (Beaglebone: Introduction to GPIOs - Using Device Tree Overlay), but what i found wasn't a basic tutorial for beginners.
Could you please recommend on such tutorial that will bring me to the phase where I write my own device tree?
Are device trees used in the ARM's "industry" (i.e. companies use them when programming their ARM Linux Products?)
Thank you.
