[Om2008.9] power on GPS

They are two routes to the same file IIRC. /etc/init.d/gpsd is a fair place to do it, but it may be overwritten if you update the gpsd package. I used to use a pair of scripts to start and stop bluetooth under 2007.2 but they should still work. You could always combine them with a check on the current power state to make it toggle, which would be better if you want to add a .desktop file. #!/bin/sh # Bring up gps - power up module and start gpsd echo 1 /sys/bus/platform/devices/neo1973-pm-gps.0/pwron /etc/init.d/gpsd start #!/bin/sh # Bring down gps - stop gpsd and turn off the module /etc/init.d/gpsd stop echo 0 /sys/bus/platform/devices/neo1973-pm-gps.0/pwron ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: [Om2008.9] power on GPS
/sys contains usually at least as many links as there are real files, i find it rather confusing but there's probably a reason. simply do ls -alF or file for both files ls -alF /sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron ls -alF /sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron most likely one of it is a link pointing to the other one. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
