I'm trying to enable and use the canbus on the BeagleBone Black. At this moment I have the can0 interface up and can receive data, but only in listen-only mode. If i change the listen-only to off, and try to use the candump utility, the only output that I get is:
$ candump can0
interface = can0, family = 29, type = 3, proto = 1
and no data from the bus appears. If I enable the listen-only mode, i can se the data comming from the bus.
I'm also having problems when trying to send data over the bus. If the listen-only mode is off, i execute
$ cansend can0 --loop=1000000 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08
it give me no errors, but I can't see anything going out to the bus. I'm using an osciloscope to monitor the beaglebone black pins (pin 26, P9) and it doesn't show anything.
I tried to check if there is anything wrong with the dto I'm using to expose the canbus on the pins, but it seems to be ok.
Any ideias of what could be happening?
