NAME

       dtc - Device Tree Compiler

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  out-
       put.

OPTIONS

       -h     Display help text.

       -q     Quiet:

	      -q - Suppress warnings.
	      -qq - Suppress errors.
	      -qqq - Suppress all.

       -I <input format>

	      Input formats are:

	      dts - device tree source text
	      dtb - device tree blob
	      fs - /proc/device-tree style directory

       -o <output file>

	      Dump the result into a file, instead of stdout.

       -O <output format>

	      Output formats are:

	      dts - device tree source text
	      dtb - device tree blob
	      asm - assembler source

       -V <output version>

	      Blob version to produce. The default is 17 (only relevant for dtb and asm output).

       -d <output dependency file>

       -R <number>

	      Make space for <number> reserve map entries (only relevant for dtb and asm output).

       -S <bytes>

	      Make the blob at least <bytes> long (extra space).

       -p <bytes>

	      Add padding to the blob of <bytes> long (extra space)

       -b <number>

	      Set the physical boot CPU.

       -f

	      Force - try to produce output even if the input tree has errors.

       -s

	      Sort nodes and properties before outputting (only useful for comparing trees)

       -v     Print DTC version and exit.

       -H <phandle format>

	      phandle formats are:

	      legacy - "linux,phandle" properties only
	      epapr - "phandle" properties only
	      both - Both "linux,phandle" and "phandle" properties

NAME

       lsblk - list block devices

SYNOPSIS

       lsblk [options]

       lsblk [options] device...

DESCRIPTION

       lsblk lists information about all or the specified block devices. The lsblk command reads the sysfs filesystem to gather information.

       The  command prints all block devices (except RAM disks) in a tree-like format by default.  Use lsblk --help to get a list of all available
       columns.

OPTIONS

       -a, --all
	      List all block devices.

       -b, --bytes
	      Print the SIZE column in bytes rather than in human-readable format.

       -d, --nodeps
	      Don't print device holders or slaves.  For example "lsblk --nodeps /dev/sda" prints information about the sda device only.

       -e, --exclude list
	      Exclude the devices specified by a comma-delimited list of major device numbers.	Note that RAM  disks  (major=1)  are  excluded	by
	      default.

       -f, --fs
	      Output info about filesystems.  This option is equivalent to "-o NAME,FSTYPE,LABEL,MOUNTPOINT".  The authoritative information about
	      filesystems and raids is provided by the blkid(8) command.

       -h, --help
	      Print a help text and exit.

       -i, --ascii
	      Use ascii characters for tree formatting.

       -m, --perms
	      Output info about device owner, group and mode.  This option is equivalent to "-o NAME,SIZE,OWNER,GROUP,MODE".

       -l, --list
	      Use the list output format.

       -n, --noheadings
	      Do not print a header line.

       -o, --output list
	      Specify which output columns to print.  Use --help to get a list of all supported columns.

       -r, --raw
	      Use the raw output format.

       -t, --topology
	      Output info about block device topology.	This option is equivalent to "-o NAME,ALIGNMENT,MIN-IO,OPT-IO,PHY-SEC,LOG-SEC,ROTA,SCHED".
