Dears,
this might be quiet an beginners/obvious issue, but I am struggeling with this
for over a week now. I tried adding support for the sun4i-can on my 4.4.0-rc2
kernel on arch. It is an A20-Olinuxino-Lime2 board.
I build sun4i-can as a module, added the corresponding entries to the dts(i)
and am able to load the driver without any errors.
[ 12.156533] No MAC Management Counters available
[ 604.004471] CAN device driver interface
[ 609.864871] can: controller area network core (rev 20120528 abi 9)
[ 609.871327] NET: Registered protocol family 29
[ 616.216629] can: raw protocol (rev 20120528)
But when I try using the device I get:
[root@Idefix ~]# ls /sys/class/net/
eth0 lo usb0
[root@Idefix ~]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: usb0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP
mode DEFAULT group default qlen 1000
link/ether 66:41:e4:77:de:35 brd ff:ff:ff:ff:ff:ff
3: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN
mode DEFAULT group default qlen 1000
link/ether 02:58:07:40:ff:c5 brd ff:ff:ff:ff:ff:ff
[root@Idefix ~]# ip link set can0 type can bitrate 125000
Cannot find device "can0"
I guess I am missing something essential here. Maybe you can advice me on the
right direction. Is there a way to get a bit more information when loading the
sun4i-can module?

Thank you a lot for your help!
