[beagleboard] Pocket beaglebone CAN is not working
Hi, Last week I got my pocket beaglebone. I am trying CAN communication. So for that I have added CAN device tree overlay in uEnx.txt as I did with beaglebone enhanced. But after booting when I am setting up network interface it is not working. When I did same thing with beaglebone enhanced board it is working properly. What extra changes I need to do to make this work. I am using IoT image without GUI from official website. Please guide me on this. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
