Has anyone found a definite fix for this yet? I get the "Memory card write error" intermittently. Sometimes the error prevents addition of a favorite. Other times, I get the error when generating a route; however, when it does this, it still generates a route.

Annoying, no?

I took a look at the permissions in the map directory, and upon first glance everything seems fine. I have more than enough free space on /media/mmc2. Given that I have the problem only intermittently, I'd guess that it's neither a permissions nor partition space issue.

I may try moving the files to my external card. I suppose I could also try uninstalling the Map application, deleting all the map data and then reinstalling. My guess is that the error has something to do with moving the file system root to the external card. I wonder if all the posters here have their OS's installed on the external card.

burmashave, wayfinder recommends uninstalling and reinstalling the software. This did not work for me. After searching the forums the problem appeared to be similar to the "memory bug" issues others have experienced. Therefore, I reformated my internal memory card and reinstalled the software. Everything works now. Hope this helps.

Saludos

Oh what a goose I am. I should have checked the mount options. The partition for my internal card is mounted read only, hence the prob. I edited '/etc/fstab' so it looks like this:

Code:
  
# /etc/fstab
rootfs	        /  rootfs  defaults,errors=remount-ro,noatime  0 0
/dev/mmcblk1p1  /media/mmc1 vfat rw,nodev,noexec,uid=29999     0 0
/dev/mmcblk0p1  /media/mmc2 vfat rw,nodev,noexec,uid=29999     0 0
The edit and a reboot seems to have fixed the problem. Note again that I installed my root partition to my external card, and this may have led to the difficulties above.

To check whether a file system is mounted read-only, run:
Code:
  
mount | grep '(ro)'
If a mount point shows up under which the 'map' directory is located, for example '/media/mmc1' or '/media/mmc2' you may have the same problem I had. Given your setup, your 'fstab' file may need to be different than mine above.

Be careful when editing '/etc/fstab'. A mistake could make your system unusable.

Also, someone more knowledgeable about the N810 may wish to weigh in here. On boot from the external card, the N810 mounts many more devices than above, and I'm not sure how they get mounted, given that there are no entries for them in '/etc/fstab'. (Pivot root for booting from external card?)
