device-tree

In the beagleboard or beaglebone are different modes to work the pin. With the previous kernel they are located in /sys/kernel/debug/omap_mux. Do u know with the last Kernel where are those files? I found many of the examples provided at hipstercircuits to be a bit overwhelming; especially if you're just looking to adjust the pins to mode 7. If anyone reading this is having the same issue, the following link may help: http://bbbadventures.blogspot.ca/2013/06/pinmuxing.html It provides the most basic template. Should the link above break, here's the snippet provided (with a few tweaks for

But I only know very little about the syntax of this file which is not enough to run Linux properly on the board. What i know now are only how to describe a unit's interrupt number, frequency, address, parent-unit and its compatible driver type (as described below): ps7_scuwdt_0: ps7-scuwdt@f8f00620 { compatible = "xlnx,ps7-scuwdt-1.00.a"; device_type = "watchdog"; interrupt-parent = <&ps7_scugic_0>; interrupts = < 1 14 769 >; reg = < 0xf8f00620 0xe0 >; } ; Other
