How to mount jffs2 in write mode ....kernel-2.4.7



Hi,

I am trying to Port Embedded Konqueror browser on Assabet + neponset board.

When I was using kernel version 2.4.3, I was able to mount flash partion in
write mode. Also I was able to run browser application from flash but not
able to load any simple html page. Also there was error in detecting key
baord and mouse event.

But when I have changed kernel version 2.4.7,hten I have following problem
1. I have created 4Mb ramsdisk & mount flash partition ( read only). New
mounted read only partition contain QT & konqueror application. When I have
tried to run konqueror application it gives following error message.
"./konqueror: error in loading shared libraries: /qt-2.3.0/lib/libqte.so.2:
unsupported version 0 of verneed record"

How to solve error " ... verneed record"?

2. When I have tried to mount with command  "mount -t jffs2 -w /dev/mtd5
/mnt" if gives following message.
"mount: blockd device /dev/mtd5 is write-protected mounting read-only"
"mount: blockd device /dev/mtd5 is not permited on its filesystem"

How to mount jffs in write mode?

3. When I have booted assabet with kernel version 2.4.7, I was able to mount 
flash partion in read-only mode.
And it was giving some error message "Older version of JFFS2 can not be used 
with newer Kernel version"
I have booted assabet with zImage of kernel version 2.4.3 in order to remove 
the QT & Konqueror files from flash partition.
After mounting flash partition of QT & Konqueror I removed them using "rm 
-rf".

After that when I booted assabet with kernel version 2.4.7, I was able to 
mount flash partion in read-only mode.
Then it was giving following error message on minicom terminal.
