2009-09-14 07:20:48     Query about non-uniform size erase blocks on Flash Chip

Hi All,

 

It is observed that,  For mounting a jffs2 file system on Flash, atleast 5 full erase blocks are needed on a MTD Partition,

 

But consider this case, where the Flash Chip is having two different sizes of erase blocks,(64 KB, 8 KB).

No.of 8KB erase blocks on the Flash chip is 4.

 

Has anyone tested like this --  Mounting the file system on a partition having 4 erase blocks region(8KB)?

 

Should another erase block be added to the partition?

 

Thanks,
