A DTB file is a Linux Device Tree Blob. Device Tree Compiler (dtc) converts between the human editable device tree source "dts" format and the compact device tree blob "dtb" representation usable by the Linux kernel. A DTB file is required on ARM Linux devices to configure and enable certain types of hardware supported by the Linux kernel. | A DTB file is a Linux Device Tree Blob.
