MTD driver

["Subrahmanyam" <subrahmanyam@navayuga.co.in>]

 Hi Stephen,

 Yes as you have said I shall setup a dedicated partition to give access a
 particular location in flash. We, have an Intel starta NOR flash which uses
 cfi command set driver, which basically i guess takes care of the erase
 operation too.  I have accessed the target through minicom tool, is this
 where i have to set up an additional partition?, can you suggest any site 
or
 procedure by which I can acheive setting up an additional partition.

 Yes, Thomas has suggested that i indeed use a filesystem, but how can I 
best
 achieve it! I mean the procedure to store data in a file.

 Thanks,
 Subrahmanyam.
