The target is <0xffffffff> and fdtoverlay fails to apply the dtbo.

You do have /plugin/ and have compiled the base device tree with overlay
support, right?

After compiling base dtbs with overlay support (make DTC_FLAGS=-@ dtbs) it works.


With,
&{/soc@0/usb} {
dr_mode = "host";
};

The target-path is "/soc@0/usb" (usb: usb@78d9000)

Right, and that's not the path you want to modify. The path you want to
modify is /soc@0/usb@78d9000. usb is the label, it's absolute, and you
can't mix and match a path ("/soc@0/") and a label ("usb")

Thanks for the clarification.

Vignesh
