Robert,
I would like to do this offline. What would I run after I copy it to ./src/arm/? Also, which parts of the code do I need keep to avoid any errors? The way I see it, my code would look something like this:
/dts-v1/;
/plugin/;
#include <dt-bindings/gpio/gpio.h>
#include <dt-bindings/pinctrl/am33xx.h>
#include <dt-bindings/board/am335x-bbw-bbb-base.h>

fragment@0 {
target-path="/";
overlay {
chosen {
overlays {
BB-BONE-NH7C-01-A0 = TIMESTAMP;
};
};
};
};
