MTD driver

[Subrahmanyam]

 Hi,

 I need to provide an user interface/GUI wherein when a certain data 
(string/key) is entered, it should basically store the key in the flash 
(this basically happens during run time after the target has been identified 
by the host).

In the target we have a flash in which there is jffs2 file system and also 
mtd drivers, since i need to store block oriented data, i am looking at the 
possiblity of using mtd driver and storing data(key) in a particular 
location in flash. How should i proceed in acheiving the same.

I will be thankful if you can best suggest an approach for acheiving the
same.

Thanks,
Subrahmanyam.
