Hi, all!
I code the program for a board on the basis of the Freescale iMX287 processor. The Linux operating system is used with version 2.6.35 kernel.
I use SocketCAN library for work with the CAN module. I connect my board to another CAN device (USB PCAN) and successfully I can send and receive data. But I can't trace a state of the CAN bus.
When I break off the bus, or change baud rate of USB PCAN, I don't receive any error messages. I’ tried the following commands to evaluate the state of the CAN module:
~$ cat /proc/net/can/rcvlist_all
receive list 'rx_all':
(any: no entry)
device can_id can_mask function userdata matches ident
can0 000 00000000 c038cbf8 c7d59c00 10 raw
(can1: no entry)
~$ cat /proc/net/can/rcvlist_err
receive list 'rx_err':
(any: no entry)
device can_id can_mask function userdata matches ident
can0 000 00000041 c038cbf8 c7d59c00 0 raw
(can1: no entry)
The command ip shows the following:
~$ ip -stat link show can0
2: can0: <NOARP,UP,10000> mtu 16 qdisc pfifo_fast qlen 64
link/[280]
RX: bytes packets errors dropped overrun mcast
0 0 0 0 0 0
TX: bytes packets errors dropped carrier collsns
20 10 0 0 0 0
Can you please tell what the problem is in?
