WP85 with CAN IIOT card


#1

Currently by following the link below, I can see the can0 interface in ifconfig.


root@swi-mdm9x15:~# ifconfig can0
can0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
UP RUNNING NOARP MTU:16 Metric:1

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)


I want to test the data communication with the CAN bus.
I have successfully compiled the killSwitch by DS from here:

After I download to the board, there is nothing coming out.
What do we expect for this application?

I have also tried to just compiled the can_open by WP85 toolchain in here:

However I got this message in the loopback test:


root@swi-mdm9x15:/tmp# ./can_open can0 --prompt
[1] [1] Error: 101
[2]

[2] Error: 101
[3] [3] Error: 101


Can anyone help on this?
