Title: Flashrom Write Cycles
Post by: amberthold on November 07, 2005, 07:44:37 am
Hello all !

I've noticed that OZ 3.5.3 uses the zaurus-internal flashrom as a writable,
hd-like disk. This is pretty cool, since you can modify *every* file now. But, AFAIK, flashrom chips have a limited number of write cycles after which they refuse any more write operations. And since OZ by default even places adressbook.xml and datebook.xml in the root-filesystem, everytime I enter an appointment, one
write cycle is consumed.

Any comments on this ?

The fs is jffs2 which performs wear leveling.

The number of write-cycles to failure is fairly large, something like 100,000 iirc, so this is a fair bit of useage.

If you want you can move /home/ to sd or cf card - maybe then it will disturb you less

Personally I prefer to have an option to write to flash (especially on c760 where it's much bigger) then to not have this possible.

I guess I will do this - A symlink to /media/sd should do the job. But how do applications react when I remove the card ? I will surely close all applications before ejecting the sd-card (what I won't do very often  ), but there might be some processes (e.g. an alarm-applet) that I can not terminate and restart comfortably.

OK ... good point

I think I will just move away those files that change everyday and then I hope the write-cycle-issue won't get that serious.
