CAN Does not work

Jump to solution

Hello,

Im trying to make CAN work. But when i try anything it says:

no such device.

But when i do:

# ifconfig -a
can0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
NOARP MTU:16 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:10
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:22

can1 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
NOARP MTU:16 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:10
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:23

 

I have a test case where CAN0 send a little bit of data to CAN1 but they don't seem to exist as a device. I don't really know why they dont exist. I tried ip link set can0 up but then its says no such device again.

What should I do?

 

Greetings,

Senkoo

Are you using the ip from busybox? That one has (or had) some problems with CAN. Try using the regular ip program.
