The dtbo file is pretty simple. It only powers on the PRUSS. Here's the dts
file to compile:
/* Minimal device tree overlay to activate PRUSS
Licence: GPLv3
(C) 2014 by Thomas{ DoT ]Freiherr[ aT ]gmx[ dOt }net
compile with
dtc -O dtb -o PRUSSDRV-00A0.dtbo -b 0 -@ PRUSSDRV.dts
*/
/dts-v1/;
/ {
compatible = "ti,beaglebone", "ti,beaglebone-black";
part-number = "PRUSSDRV";
version = "00A0";
fragment@0{
target = <&pruss>;
__overlay__ {
status = "okay";
};
};
};
All that 'magic' comes with the libpruio binary.

libpruio contains
- ARM software as user interface (can get compiled on every kernel
version)
- PRU software to control the hardware (for ARM33xx CPU family)
So can use any kernel version. (I build the binary on 3.8.13-bone37.)
