Three steps: Enable CAN overlay by configuring cape manager Configure network interface Install startup program 1. Enable CAN overlay Add following line in /etc/default/capemgr CAPE=BB-DCAN1 2. Configure network interface Add following lines in /etc/network/interfaces auto can0 iface can0 inet manual pre-up /sbin/ip link set $IFACE type can bitrate 1000000 listen-only off up /sbin/ifconfig $IFACE up down /sbin/ifconfig $IFACE down 3. Install startup program Setting the CAN interface to /etc/network/interface does not enable the CAN interface on startup for some reason. In order to workaround this problem, I installed a startup program as follows. Following link was helpful: Running a script on Beaglebone Black boot/ startup The startup script to run…

I've tried to enable CAN on my BeagleBone Green board. I had to stop the work before verification, because my logic analyzer is unavailable now. I record what I did in this article to make things reproducible when the logic analyzer is back. There are several helpful links: http://www.embedded-things.com/bbb/enable-canbus-on-the-beaglebone-black/ http://electronics.stackexchange.com/questions/195416/beaglebone-black-can-bus-setup https://groups.google.com/forum/embed/?place=forum/beagleboard&showsearch=true&showpopout=true&showtabs=false&hideforumtitle=true&parenturl=http%3A%2F%2Fbeagleboard.org%2Fdiscuss%23bone_forum_embed#!category-topic/beagleboard/can/SjWwVngIPh8 Readings to understand device tree overlay: Device Tree for Dummies: http://events.linuxfoundation.jp/sites/events/files/slides/petazzoni-device-tree-dummies.pdf Device Tree Overlays (in adafruit) https://learn.adafruit.com/introduction-to-the-beaglebone-black-device-tree/device-tree-overlays Here are what I did: # make a workspace root@beaglebone:~# mkdir can root@beaglebone:~# cd can root@beaglebone:~/can# pwd /root/can # check if CAN is enabled ... no root@beaglebone:~/can# dmesg | grep can # take backup of the original device tree blob file for…
How to login from MacOS: Connect to the BeagleBone by a USB cable. MacOS restart is necessary for some reason.
