树莓派Zero W - LIRC无法工作 - 无法启用设备。

Question

我之前安装了lirc。 我的文件boot/config.txt包含：

dtoverlay=lirc-rpi

/etc/lirc/hardware.conf 文件包含：

#
# 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状态时

当我输入sudo mode2 -d /dev/lirc0时，出现了以下错误：

Using driver default on device /dev/lirc0

Cannot initiate device /dev/lirc0

有没有人能给我建议，如何解决这个问题？

最近的lirc更新是一个重大的、破坏性的更新。作为入门，usr/share/doc/lirc/README.Debian.gz上有升级说明。此外，http://lirc.org/html/configuration-guide.html的官方文档提供了更新的、全面的操作指南。

请注意，hardware.conf在当前的lirc版本中不再使用。此外，lirc大量使用systemd——sysV脚本可用，但维护不太好。

简而言之：阅读文档并进行必要的升级步骤。
