I had issues with a workshop I run in Nantes, with Pi and Arduino with Pd. A simple tone patch like the one you describe would open fine from the /etc/rc.local script, but not the patches that use [comport]. The solution to that was to include this line in /etc/rc.local su -c '/usr/local/bin/pd -nogui -open /home/pi/path/to/patch.pd &' - pi &
This will launch Pd as the pi user and not as root. It seems that [comport] doesn't like root. All this, if your problem is launching your patch on boot.
