I don't know if the implementation of w1 works on your board, but we can
try to address any problems.
First, you have to run owfs as root to use w1. Communication is through
netlink and linux only allows that for the root user.
Second, if you run with the "--debug" flag and post the startup sequence we
can get a better idea of what is happening.
