mkfs.jffs2

[Narinder Kumar]

Hi all,

             This is my first mail to the group and is hoping for some 
fruitful results from your mails. I am having problems in mounting my 
MTD device using mkfs.jffs2 . Though i have read mails on the group 
regarding mkfs.jffs2 but still i am not able to decipher my problem, so 
hoping a helpful hand from your side. Here are the steps that i am 
following:

eraseall -j /dev/mtd/1           ( -j as i need jffs2 file system 
/dev/mtd/1 is 1 MB partition)
mkfs.jffs2 -e 0x420 -d /tmp/Application -o image  ( created image of my 
application which is to be put into MTD)
cp image /dev/mtd/1           ( copied the image into MTD)
mount -t jffs2 /dev/mtdblock/1 /mnt is giving errors

Node at 0x00000048 with length 0x000006d2 would run over the end of the 
erase block
Perhaps the file system was created with the wrong erase size?

 From the output atleast i am sure that i am providing the right 
eraseblock to mkfs.jffs2 as Erase block is checking at an interval of 
0x420 everytime. When all these messages stops , i entered into /mnt to 
check if there is something in the mounted device and it does shows 
everthing that i copied into it, so why is this error coming ?
"Node at 0x00000048 with length 0x000006d2 would run over the end of the 
erase block" can this helps me out somehow where something is going 
wrong ???
