SYNOPSIS

/usr/bin/dtc [options] <input file>

DESCRIPTION

Device Tree Compiler, dtc, takes as input a device-tree in a given format and outputs a device-tree in another format for booting kernels on embedded systems. Typically, the input format is "dts", a human readable source format, and creates a "dtb", or binary format as output.

-b <number>
