Beaglebone black에서 CANbus 인터페이스를 불러올 수 없습니다.

시작 시 인터페이스를 자동으로 불러오기 위해 /etc/network/interfaces다음과 같이 파일을 편집했습니다.

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

그리고 파일 끝에 다음을 추가합니다.

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

$ sudo /sbin/ip link set can1 up type can bitrate 250000하지만 재부팅할 때 작동 하도록 하려면 여전히 작업을 수행해야 합니다 $ candump can1.

어떻게 해야 합니까?

[업데이트] 차이가 있을 경우를 대비해 이것은 내 전체 "/etc/network/interfaces/"입니다.

# 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>
