============
|

|
||||
This library should be merged into dtc proper.
|

This library should likely be worked into U-Boot and the kernel.

IV - Utility Tools
|
||||
==================
|
||||
|
||||
1) convert-dtsv0 -- Conversion to Version 1
|
||||
|
||||
convert-dtsv0 is a small utility program which converts (DTS)
|
||||
Device Tree Source from the obsolete version 0 to version 1.
|
||||
|
||||
Version 1 DTS files are marked by line "/dts-v1/;" at the top of the file.
|
||||
|
||||
The syntax of the convert-dtsv0 command line is:
|
||||
|
||||
convert-dtsv0 [<input_filename ... >]
|
||||
|
||||
Each file passed will be converted to the new /dts-v1/ version by creating
|
||||
a new file with a "v1" appended the filename.
|
||||
|
||||
Comments, empty lines, etc. are preserved.
|
||||
|
||||
|
||||
2) ftdump -- Flat Tree dumping utility
|
||||
|
||||
The ftdump program prints a readable version of a flat device tree file.
|
||||
|
||||
The syntax of the ftdump command line is:
|
||||
|
||||
ftdump <DTB-file-name>
