Re: mkfs.jffs2 ?!

[Manuel Sahm <Manuel.Sahm@feig.de>]

Hello,

I have make a pertition of 5 MB through the Kernel Partitioning.
my jffs2 Image has a size of 128kB

If I mount the jffs df -h says:


Filesystem               size      used        available   Use%       
Mounted on
/dev/mtdblock5       5.0M   388.0k   4.6M        8%            
/media/DATAfs  

If I write to /media/Datafs, does the system automatically increase my 
mounted jffs image ?

I defenitly have the right erase size ----- maybe it is an endian problem ?
How could I see which endian I need (little or big) ?

Thank you
