This is similar in effect to putting a capacitor on all the signal lines, not just the clock line that is affected by the hardware mod. I have no difference in GPS performance if rootfs is in NAND or on SD, and I have no hardware mod. The capacitor makes the SDcard less noisy - even when it is being used all the time.

Re: shr- GPS howto?
Thanks, arne, Helge, I just made my second try this morning and I got a lock in 35 secs (tried two times, consistent lock time). 8-) I don't know why the different behaviors, but I did the tests inside a party tent I've in the garden and after reading how GPS behaves in weather (rain, cloud, snow makes no perceptible difference), the only thing that comes to my mind is that last time the tent was probably wet or might even had a thin layer of ice (temp was 0ºC). I don't know if it was sufficient to compromise the reception (tent now is dry), but I'll test it again when I get similar conditions. Cheers, Fernando arne anka wrote: slot.

These days, no option for turning the gps hardware on or off. Gps is turned on automatically by fso-gpsd, when an app tries to use it. - it took at least 4 minutes to get a fix. Last time, I gave up after 10 min. All tests this evening, same place, tallest buildings almost 100mt away; my house is ~10mt high. Check if you have one of the older freerunners that have problems using gps and SDcard at the same time. Take the sdcard out, and rund from flash. If the gps is better, then that was the problem. You should also be able to see a tiny capacitor between two of the pins under the sdcard slot. If it isn't there, then your phone have this problem.

Open shr settings (one of the icons) and make sure gps is on there. I don't need any sys/class stuff to use the gps with SHR. SHR image of dec.16 should be ok, one of the earlier ones had gps not working. Also, not all alternative kernels have working gps. Go outside, get away from tall buildings. Start tangogps, stand still. It may take 2 minutes to get a fix with some bad luck. Moving around makes this worse. Tall buildings make this worse. Starting tangogps indoors and then going outside may take more time. So if you look at the map indoors, restart tangogps when you get outside. The gps may or may not work indoors - if you come in from outside. Don't expect the gps to start up indoors though. don't expect gps to work at all in a building with several floors above you. Gps units generally need a stronger signal to start up, then they can follow weaker signals in less than ideal areas. But it won't start up in bad places.

Re: shr- GPS howto?
You don't need to power on the GPS device yourself, FSO will handle this for you when a client requests the GPS resource (and then power it down again when there are no longer any clients using it). You'll get empty data until the device acquires a fix. From what I've read elsewhere it seems important to make sure that your time-zone settings and date/time are correct, as it seems FSO uses these when getting a fix. Cheers, Mike.
