In fact, I have 64k space left for saving configuration data. The size of a sector is 64k normally except the bottom sectors that are 8k, 4k, 4k, 16k, 32k. So you see, I have five sectors to run JFFS rather than one 64k sector. Then, is it possible to run JFFS on these sectors? -----Original Message----- From: Charles Manning [mailto:manningc2@actrix.gen.nz] Sent: Tuesday, December 10, 2002 3:07 PM To: fred@sc23.sc.mcel.mot.com Subject: Re: Which filesystem can live on one flash sector?

I don't see how any fs - alive or dead - could live in one sector. You need at least one free sector to do garbage collection. (more for any real file system). Sounds to me like you'll just have to use it as raw flash. -- Charles
