我以前安装过lirc。我的文件 boot/config.txt 包含：

dtoverlay=lirc-rpi

文件 /etc/lirc/hardware.conf 包含：

#
# Arguments which will be used when launching lircd
LIRCD_ARGS="--uinput"

#Don't start lircmd even if there seems to be a good config file
#START_LIRCMD=false

#Don't start irexec, even if a good config file seems to exist.
#START_IREXEC=false

#Try to load appropriate kernel modules
LOAD_MODULES=true

# Run "lircd --driver=help" for a list of supported drivers.
DRIVER="default"
# usually /dev/lirc0 is the correct setting for systems using udev
DEVICE="/dev/lirc0"
MODULES="lirc_rpi"

# Default configuration files for your hardware if any
LIRCD_CONF=""
LIRCMD_CONF=""

当我尝试启动 sudo /etc/init.d/lircd status

当我提示时： sudo mode2 -d /dev/lirc0 发生此错误：

Using driver default on device /dev/lirc0

Cannot initiate device /dev/lirc0

任何人有一些建议我可以如何解决这个问题？

最后一次 lirc 更新是重大的，破坏性的。在 usr/share/doc/lirc/README.Debian.gz 上有升级说明。此外，http: //lirc.org/html/configuration-guide.html上的官方文档有一个更新的、全面的操作指南。

请注意，在当前的 lirc 版本中未使用 hardware.conf。此外，lirc 大量使用 systemd —— sysV 脚本可用，但维护得不是很好。

简而言之：阅读文档并进行必要的升级步骤。
