Сравнить два файла дерева устройств
root@orangepizero2:~# dtdiff --help
Usage: dtdiff <device tree> <device tree>
root@orangepizero2:~#
На самом деле, инструмент dtdiff - это bash-скрипт, который проверяет формат файлов,
при необходимости с помощью утилиты dtc преобразует файлы dtb в dts,
а затем выполняет команду diff -u
( -u, -U NUM, --unified[=NUM] output NUM (default 3) lines of unified context)
выводить заданное количество строк после отличий (по умолчанию 3)
Текст скрипта:
Источник: https://github.com/qemu/dtc/blob/master/dtdiff
--------------------
#! /bin/bash
# This script uses the bash <(...) extension.
# If you want to change this to work with a generic /bin/sh, make sure
# you fix that.
