WebSo, each time I modify the device tree I typically change the dts in a custom recipe and rebuild the image. The rebuild takes a long time since it rebuilds the entire kernel, and then the image needs to be built and finally deployed to the target device. Is there any trick that I'm missing that rebuilds only the device tree? UPDATE: http://www.ofitselfso.com/BeagleNotes/Beaglebone_Black_And_Device_Tree_Overlays.php
