I have script that runs at startup which initializes the CAN communication on my BBB. Whenever I restart my BBB this script does work most of the times, I would say 7 out of 10. Once the CAN is up successfully it never stops in middle of working. Then I generally use Candump to fetch all the values from CAN bus. The only issue is, sometimes on reboot I get the error message saying "Read: Network is Down". So I am wondering what is the possible issue from BBB side.
