[edit] gpsd device-hook

With the device-hook script below gpsd will use gta02-gps to retrieve and store agps data. Do NOT start gpsd with the -n option, because then it will never deactivate the gps device.

An issue that needs to be resolved: gpsd doesn't deactivate the device until 60 seconds after the last client disconnects. If the device suspends during those 60 seconds the kernel will power down the gps and the agps data will be lost.

  • The 60 second timeout should be made configurable (and in our case be set to something low like 2 seconds).
  • Another solution would be to have the suspend script check if gps is powered on and ifso don't suspend. Or even better set "om gps keep-on-in-suspend 1" and schedule a (rtc) wakeup in 60 seconds.

/etc/gpsd/device-hook : 

DATA=/var/cache/gta02-gps/agpsdata # nobody:dialout a=r,u+w 
agps=/usr/local/bin/gta02-gps

case "$2" in
"ACTIVATE")
        mdbus2 -s org.freesmartphone.ousaged /org/freesmartphone/Usage \
                org.freesmartphone.Usage.SetResourcePolicy GPS enabled
        $agps --setup-serial $1 --load-agps $DATA
        ;;
"DEACTIVATE")
        for i in 1 2 3
        do
                $agps --setup-serial $1 --dump-agps $DATA.new || continue
                [ $(stat --printf="%s" $DATE.new) -lt 1024 ]  && continue
                mv $DATA.new $DATA
                break
        done
        mdbus2 -s org.freesmartphone.ousaged /org/freesmartphone/Usage \
                org.freesmartphone.Usage.SetResourcePolicy GPS auto
        ;;
esac

exit 0

If you don't use the fso resouce, just make a call to "om gps power" instead.

Bought a 2.5mm to 3.5mm converter cable (sku.7127 at dealextreme).
It has the following pin-layout: TRRS: left, right, mic (unconnected), ground

Unfortunately this is incompatible with the FR which uses TRRS: mic, right, left, ground

Currently running a 2.6.34-oe4+gitr3 kernel from shr-kms with debian (squeeze/sid) as OS.

The touchscreen was misconfigured (could not reach all the corners with the cursor, and also the axes were messed up) in X. Calibration failed as there's no longer a /sys/.../calibrate. Also the option in the InputDevice section where ignored as udev (157) was already providing the input device. So I fixed it by removing the unused inputdevice section and adding: 

Section "InputClass"
    Identifier              "S3C24XX TouchScreen"
    MatchDevicePath         "/dev/input/event1"

    Option "GrabDevice"     "1" 
    Option "InvertY"        "1" 
    Option "Calibration"    "110 920 110 920"
    Option "SwapAxes"       "1"
EndSection

note: /etc/pointercal doesn't seem to be used anymore
