The only thing that I could attribute it to, is unexpected power-downs by: - Removing battery - Very low power and subsequent emergency power down Whenever I his this, I reflashed, but about a week or 2 ago, I just rebooted again. To my amazement, the file system somehow 'restored' itself and got mounted rw. After that incident, I've run into a few other 'mounted ro' situations (power consumtion seems to've gone _way_ up lately!!), and I've had this 'reboot and pray' situation pay off every time up to now. I haven't checked what happens when I start up w/ debug messages.

Ah well, it's in the bug tracker, I think...

SHR Qi booting: alignment trap, broken UBIFS
In earlier posts I mentioned that my ubifs filesystem was mounted readonly, which shouldn't be the case. I've trace this down now: Flashing kernel and rootfs freshly (July-21 version), having Qi installed, I longer press the Power button to see debug messages. There are millions of 'alignment trap' messages. Also, the ubifs driver complains about corrupted filesystem with a defered reparation. The reparation seems to work after two or three reboots, until then the filesystem remains readonly. I also have the effect that I cannot pass the 'set root password' dialog of the first time configuration wizzard. The 'alignment traps' disappear (of course) when I boot without debug output, but I'm wondering if this is normal and if this doesn't still cost some boot time?

I, as initiator of this discussion, first have to apologize for my assumption that latest SHR still cannot handle GPS. It can, I now made the same observations as Sylvian did: GPS receiver quality is poorer, TTFF is slower, but it works. I have two FreeRunners (one for testing new releases) and that one had the GPS cable broken. I think it was from the many times 'shaking out that battery'. I managed to re-solder it somehow but with only little success: I only get the GPS time, but no fix, and it seems to mee that this also only works on the January (or comparable) release of SHR, not for actual (July) ones. Finally I'm glad to have navit working again, since I'm about to go to a business trip from Germany to US, having a rental car there with probably no navigation on board ;) A.___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
