Dear all,
i have a custom board with GPS antenna (on /dev/ttymxc3) and gpsd service installed. My problem appears at boot time because when the daemon is started, it cannot open the device correctly and give me these errors:

linaro-alip gpsd[1250]: gpsd:ERROR: device open of ttymxc3 failed: No such file or directory - retrying read-only linaro-alip gpsd[1250]: gpsd:ERROR: read-only device open of ttymxc3 failed: No such file or directory
linaro-alip gpsd[1250]: gpsd:ERROR: ttymxc3: device activation failed.
linaro-alip gpsd[1250]: gpsd:ERROR: ttymxc3: activation failed, freeing device

Instead, when I start the daemon manually typing "gpsd -N -D3 -F /var/run/gpsd.sock /dev/ttymxc3" or when i put this line into "/etc/rc.local" file, it works correctly and I can see the right coordinates with "gpsmon" program.

Is this a simple configuration problem?

P.S. I can see data from GPS also typing "gpsmon /dev/ttymxc3"
