Grab the "dtb-rebuilder" and select a branch based on the kernel you are using.. https://github.com/RobertCNelson/dtb-rebuilder For example: v4.1.x-ti: https://github.com/RobertCNelson/dtb-rebuilder/blob/4.1-ti/src/arm/am335x-boneblack.dts change: #include "am335x-bone-common.dtsi" -> #include "am335x-bone-common-no-capemgr.dtsi" and overlays will be disabled..
