无法在 Beaglebone black 上调出 CANbus 接口

为了在启动时自动调出界面，我对文件进行了/etc/network/interfaces如下编辑：

debian@beaglebone:~$ sudo nano /etc/network/interfaces

并在文件末尾添加以下内容：

auto can1
iface can1 inet manual
    pre-up /sbin/ip link set can1 type can bitrate 250000 #triple-sampling on restart-ms 100
    up /sbin/ifconfig can1 up
    down /sbin/ifconfig can1 down

但是当我重新启动时，我仍然需要做$ sudo /sbin/ip link set can1 up type can bitrate 250000才能使其$ candump can1正常工作。

我应该怎么办？

[更新]如果它有所不同，这是我的整个“/etc/network/interfaces/”

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#auto eth0
#iface eth0 inet dhcp
# Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE

##connman: ethX static config
#connmanctl services
#Using the appropriate ethernet service, tell connman to setup a static IP address for that service:
#sudo connmanctl config <service> --ipv4 manual <ip_addr> <netmask> <gateway> --nameservers <dns_server>

##connman: WiFi
#
#connmanctl
#connmanctl> tether wifi off
#connmanctl> enable wifi
#connmanctl> scan wifi
#connmanctl> services
#connmanctl> agent on
#connmanctl> connect wifi_*_managed_psk
#connmanctl> quit

console


auto can1

    pre-up /sbin/ip link set can1 type can bitrate 250000
    up /sbin/ifconfig can1 up
    down /sbin/ifconfig can1 down

答案1

真对不起。通过查看整个etc/network/interfaces，我注意到有一行奇怪的内容：

console

就在该auto can1线上方。我相信这是有人在文件中输入错误。

通过删除该行，界面按最初预期启动。

谢谢大家
