i have a brief question:
Using kernel 3.14 on a similar sabreauto board, with "ip addr show" after first boot i see
2: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN qlen 10 link/can
This is correct when there is not CAN communication.
bash-3.2# ip link set can0 type can bitrate 1000000 triple-sampling on bash-3.2# ip addr show 2: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN qlen 10 link/can bash-3.2# ip link set can0 up 2: can0: <NOARP,UP,LOWER_UP,ECHO> mtu 16 qdisc pfifo_fast state UNKNOWN qlen 10 link/can
As you can see, after set to "up", final state is UNKNOWN.
It stays UNKNOWN also while communicating. Communication with remote host BTW works.
Is this UNKNOWN state a signal i set up something wrong in the kernel ? Do i have to worry about ?
